The first page.. This is an era of "HD".


Objectively speaking, television has infiltrated into the hundreds of millions of Chinese families, as the basic element of social existence. And even basic necessities, like, become an indispensable element of life. Involved in high-definition television is the first range, is mainly in the areas of high-definition. .


But the high-definition of scope can be much more than an HDTV can explain it clearly, and it includes a high-definition DV, HD, PC, HD projectors, high definition video, high definition discs (Blu-ray and HD-DVD) as well as the PS3, Xbox 360 and other high-definition video game, perhaps in the future we will have more on high-definition of definition and terminology.


This year is the year of HD rapid development, we not only see the HD in the traditional areas made some progress, even antennae have been out into the PC industry. Because now the next generation of high-definition Blu-ray player because no integrated storage camp can not be developed, the market of the few high-definition player either because the price is too high, is small workshop or DIY products, plus into pieces on the very scarce resources, and now as a task of high-definition players can fall into the PC body. .


PC because of the cause of universal processor CPU, as long as they have a strong sex to the input terminals (network ones), output (HDTV, a large size monitor), you can implement a freelance HD player functionality. However, high-definition video is not a good role and, in particular, and now moving the 1080P 20mbps rate of ones, so that now even the most cattle b Core 2 Duo are overwhelming. Has been, mpeg decoding are done by video card to complete, when the HD to a graphics card makers also see business opportunities, respectively a new generation of graphics cards in integrated video decoder, CPU, much share the burden, The PC can be fully competent in the HDTV player work. .


Our presentation is also begins. Please select your favorite section, or follow the order step by step to understand HD..


The second page. . HD history and current situation. .


Objectively speaking, TV has hundreds of millions of Chinese families, to become one of the basic elements of social existence. Even the basic necessities, and became the indispensable elements of life.


I remember a few years ago, everywhere in the noise made on the digital / digital TV concept, which is the first DTV initial type. Use of digital (digital) as the transport / storage format, and give up the traditional analog way, is with the PC developed new technology has affected the traditional areas of home appliances. .


Digital transport/storage of maximum advantage is you can do better, bigger storage content, in fact, traditional analog current high-end technology remains now numbers cannot be overloaded; instead, transport, storage can be lossless--this is to copy the files on the PC that, if there are no exceptional circumstances whatsoever, whether or not copy the file many times, and most of the original file is exactly the same. While the analog signal, even more clear, low distortion of RIP 10 times, the result is a miserable. The digital signal of the biggest advantages is that it is possible to do without distortion.


It is whether the distortion of the basis for the emergence of HD was able to birth and renewal-HDTV (High Definition Television) is defined as output high-definition digital TV technology. .


Although the HD is now the most IN terms of, you can be sure to 1970. -Definition of development history is a history of the "three kingdoms", went to Japan, Europe and America's troubled controversy.


Japan and Europe, although the research was the first high-definition, but at the time of the computer development and the surrounding development is still at the initial stage, we can only use analog technology. This is also their Achilles heel high definition technology. .


This status until the United States means that the high-definition technology in future long-term strategic value, in 1996, the use of its own high-tech technical and digital infrastructure, FFC ATSC Digital television standard for adoption as an American national standard, in 1998 the first digital broadcast HDTV programs, the representative of the true meaning of HDTV, HDTV also laid the groundwork for America's leadership. In the United States established the digital road for Japan's high-definition is almost a devastating blow. Fortunately, however, Japan has the advantage of the digital sense, after the research is also transferred to the figures, and from this, the basis of the digital high-definition standards established under the. .


But in China, full-HD era is in the creation of high-definition channels to CCTV represents.


The third page. . The concept of primary HD Getting Started - Glossary. .


But there are quite a few friends for the concept of high-definition of the concept of ambiguity, the author here briefly. HDTV (High Definition Television) is a high-definition digital TV output technology, "high-definition, can provide compared to traditional analog TV technology more high definition image quality. HDTV-high definition of the main problems it supports 1280 x 720, 1920 × 1080, respectively, 1080I/1080P 720p..


720/1080 refers to the resolution of 1280 × 720 and 1920 × 1080, that I and P are the mean? I on behalf of interlace, interlaced scanning. .


Is a Progressive, progressive scan. 720P bandwidth with 1080I, 1080I in sharpness is naturally higher in dynamic screen showed a smoother is 720P. And 1080P is taken into account the clarity and dynamic performance requirements also said, FULL HD, but it is also on the bit rate, the maximum storage space requirements for the format.


Speaking of digital, then we are sure to calculation of capacity, the length of each piece varies, the same size, but if with a total capacity divided by the time I could arrive at a comparable variable - bit rate. Determine the rate and time of a film's total capacity, while rate of the encoding / decoding processor will provide the appropriate requirements. In general, the higher the bit rate, the more clear sharp images, the more fluent, but storage capacity, and encoding / decoding requirements more stringent. .


HDTV in addition to the rate on a different encoding format, there are also different, now there are mainstream video, MPEG4, MPEG2. H .264 (MPEG4 AVC),/WMV9HD VC-1 (AVC-1). Different formats of compression and performance are vary, we will have a dedicated, now online often has only three, MPEG2, H .264, VC-1. ". Audio encoding format is AC3, DTS, AAC has recently EAC3 has meaning.


Because now many new sources are downloaded from the internet, the source of these films are usually repackaged over the, the Mudi is Weiliaogenghao the Cunchuyiji Chuan Shu, and with the many Changshangjili Tuiguangziji the encapsulation formats Now the Internet has a lot of packaging formats such as AVI, TS, MKV, the package format is the container, and video encoding and audio encoding is quite is so vegetables and rice, how to install, these meals, with the bowl and the pot there are certain requirements . This we have a dedicated following. .


Finished high-definition software/specifications section, we describe the hardware part.


From the DVD + /-W format began, the two camps to battle it out, eventually no one can conquer who, so the war would continue into the Blu-ray format war. Why is called Blu-ray, Blu-ray next generation optical disc belongs to the scope of its core technology to replace the red laser DVD blue laser storage technology in order to achieve higher capacity. .


Blu-Ray Disk is blue CD, DVD, next-generation standards, leading to Sony and Toshiba, Sony, Panasonic, Philips, has been a pioneer, Hitachi, Samsung, LG and other giants of support. The storage principle for Groove records, using the traditional Groove records, but by more advanced shake fibrillation addressing the larger capacity of storage and data management, has now reached 100GB shocks. Unlike traditional CD or DVD storage form BD discs than obviously bring better reflectivity and storage density, which is the key to achieving breakthrough capacity. .


In contrast with the Blu-ray is HD-DVD camp, the original Toshiba has joined the Blu-ray camp, however, the distribution of benefits and technical features related to induce Toshiba categorically withdraw from the organization in favor of joint NEC developed Advanced Optical Disk, and get the DVD-Forum support and renamed HD DVD. As the Blu-ray DVD and current DVD format is not compatible with a direct increase of the transition to Blu-ray DVD manufacturers cost of production inputs, thus greatly delayed the next generation Blu-ray DVD standard process.But another key members of the DVD Forum is a Toshiba and Blu-ray is not compatible with the new technology of AOD (Advanced Optical Disk) discs. By Toshiba and NEC joint launch of AOD technology compared to blue laser's biggest advantage is compatible with the current DVD, and also in the production of more difficult than Blu-ray DVD industry is much lower.


HDMI: HDMI full name in English is "High Definition Multimedia", meaning the Chinese High-Definition Multimedia Interface. HDMI interface can provide up to 5Gbps data transmission bandwidth, can send uncompressed audio signal and high-resolution video signals. At the same time without the signal before transmission / A or A / D conversion, can guarantee the highest quality audio and video signal transmission. HDMI and DVI on the pin-compatible, but with a different package, but its structure still has many differences. .


HDCP stands High-bandwidth Digital Content Protection, which is a "high-bandwidth digital content protection". Simply put, HDCP is to pass through the DVI interface of digital signals are encrypted, multimedia content issued-(computer, DVD, set-top boxes, etc.) and accept-Terminal (monitors, televisions, projectors, etc.) plus line of protection. This layer of protection is not primarily used to prevent the digital signals through illegal copying, but the content of the digital signal is encrypted so that illegal copying can not be accurate content, satisfactory results. HDMI and DVI have HDCP function can, of course, depending on the transmitter and receiver equipment. .


4. never compromise of two great Blu-ray camp (on).


We are using mainstream optical storage DVD early in 1996 set the standard.DVD-VIDEO movie resolution 720x480 (NTSC) or 720x576 (PAL), belong to the standard definition video (Standard-Definition, SD, standard definition) a few years ago it seems maybe the picture quality is very good, but times have changed, and now is the high-definition video (HD, High-Definition, standard definition) and big screen TV era, once experienced the effects of high-definition television, who are satisfied with the standard definition video.


DVD of the awkward position of now is almost just as the CD, as shown in Figure 1, we can see the capacity of storage media, video streaming data and video storage time of their relationships.Single sided single layered DVD capacity ceiling near 5GB from VHS video, low-definition video to standard definition video, DVD-video disc can store hours, from 7 to 2 hour (General DVD movie in 4Mbps-6Mbps), and then drops to a 1-hour (standard-definition video to the highest specifications), but if you want to store 20Mbps-30Mbps high-definition video and DVDs can only be set aside for approximately 20-30 minutes, plus DVD slow transfer speeds, the DVD already outdated situation. The body of a new generation of magneto-optical storage increasing demand, bear the brunt of the film industry, film industry on the next generation of magneto-optical storage body made the following demands. .


1. civil specifications and PC specifications must be consolidated, 2, you must have the perfect copyright protection technology, 3, you must have sufficient capacity and manufacturing costs must be controlled in the same as with the existing DVD. You may not use a dedicated disk cartridge. 4, can achieve high definition resolution of 1920 × 1080 to be met with a variety of aspect ratios, and other functions. 5, can achieve a multichannel audio, and other functions. 6, can play DVD video discs and previous standard audio format. 7, and Internet collaboration features. Dialogue-oriented operations can be realized. 8, you can use the existing DVD authoring tools. 9, to ensure reliability, such as ensuring the same standard CD playback compatibility. .


The generation of a new generation of magneto-optical storage for two candidates, HD-DVD and BLU-RAY DISC. HD-DVD camp to Toshiba, including Microsoft, NEC, Sanyo, Intel and other vendors and universal pictures and film companies, BLU-RAY DISC camp to Sony and Panasonic as, including pioneer, Philips, Samsung, Apple, Mitsubishi, pioneer, sharp, LG, etc. manufacturers and Fox, Walt Disney and other film companies.


BLU-RAY DISC uses a shorter wavelength blue laser (Blue laser, or Blue Ray), which is the name of the "blue" the origin, BLU-RAY uses a blue laser wavelength of 405nm, greatly reducing the groove length and interval, which can record several times higher than the DVD for more information. .


HD-DVD similarly uses a 405nm-wavelength blue lasers, however, the track pitch HD-DVD 0.40 m, μ is greater than 0. BLU-RAY DISC-32 μ m, therefore the same circumstances HD-DVD logged data capacity would not and the same BLU-RAY DISC as a single-layer discs, a Blu-ray disc capacity, while 25GB HD-DVD 15GB CD capacity.


Page 5: never compromise on the two Blu-ray camp (the next). .


Blu-ray disc physical specifications and CD/DVD discs with a diameter of almost exactly the same, and still the same as a CD, DVD, thickness also 120mm is 1. .2mm, central hole and other data are identical. Currently published single sided single layered, single-sided double-layer two kinds of specifications. Single-sided single layer Blu-ray disc capacity 25GB (actually there are 23. .3GB, 25GB, 27GB three), single-sided double-layer Blu-ray disc capacity 50GB. Speed, BLU-RAY DISC 1-speed read and write speeds are defined as 36MB / s, there are now 4-speed of the Blu-ray drive can write, read and write speed that its up to 144 MB / s , such a high speed to meet the real-time playback of high definition video and high-definition game play requirements, compared to, CD-ROM of a speed to 150KB / s, 52X CD-ROM speed is only 7. .62 MB / s, DVD-ROM speed is 1 to 1. .32 MB / s, 16X DVD-ROM speed of just 21. .12MB/s, in the face of high-definition video can be said to be deficient.


BLU-RAY DISC has ambitious plans, single-sided 4 layer and single-sided 8 layer Blu-ray Disc and the corresponding drive has been under development, single-sided 4 layer Blu-ray disc capacity will reach 100GB, while the single-sided 8 layer Blu-ray disc capacity is up to 200GB. BLU-RAY DISC speed of the future will be raised to 6X, and more. .


Currently there are three HD-DVD discs are HD-DVD specifications, including: single-sided single layer and single sided dual layered of 3X DVD-ROM, this is actually an improvement of the DVD disc, as the name suggests, it is three times the DVD of "enhanced version," in the same capacity and DVD-ROM, there is a single-layer capacity is 4. .7GB there is the capacity of single-sided double-layer 8. 5GB, the other three can be seen as the new HD-DVD, including the single layer of the HD15, a capacity of 15GB, dual-layer HD30, a capacity of 30GB, single layer of the HD45, a capacity of 45GB, The HD-DVD the same naming rules and DVD. The other is HD-DVD and the SD-DVD hybrid specification, one is single-layer HD-DVD + single SD-DVD, CD-ROM for the double-sided, a capacity of 15GB +4. .7 GB = 19. .7GB, one is a single-layer SD-DVD HD-DVD + CD for double-sided, 15GB + 8. .5GB = 23. .5GB, one is a double-layer SD-DVD HD-DVD + CD for double-sided, with a capacity of 4. .7GB 30GB + = 34. .7GB, one is a double-layered HD-DVD + SD-DVD, disc has a capacity for 2-sided, 30GB + 8. .5GB = 38. .5GB. The last category is the HD-DVD and SD-DVD double standard, only a single sided single layer, single-sided single-layer disc at one level is the HD-DVD, a layer is the SD-DVD, the capacity is 15GB + 4. .7 GB = 19. .7 GB. Higher capacity, more layers of HD-DVD currently under development and expected to single-layer capacity of 20GB or higher can be achieved. .


Currently, BD occupy film support, films, and other strong circulation, as well as the PS3 advantages brought about by the software publisher, technology and technical reserves are more advanced than hddvd.


HDDVD will hold production line configuration, hardware costs, copying costs, integrated hardware and software costs, and other areas. .


So now it seems to prevail, but BD BD and HDDVD not yet entered a large number of popular stage, both hardware and software sales can be said is very low, to become the mainstream will also need a longer time, so now the short term have not yet been able to determine their success or failure. Who can first player price dropped to breakthrough consumer psychology and get more content provider's support, the most important will be the key to victory.


These two standards of who was superior and who is difficult to say with 23 clear, although there are two competing camps to bring technology updates and lower prices, but for end users, the complexity of the standard makes it more difficult to achieve compatibility to the present situation, it is possible end-user needs will be different according to their own camp to buy one or two single. .


Page 6: compression is key-HDTV encoding process.


Now that the progress from DVD to HDDVD / BD, we see that not only increases the capacity of storage media, and video compression technology in recent years has also been rapid growth. We can do some calculations, storage capacity increased by 5 to 10 times, while the video compression technology can improve if 2 to 3 times, then we will be in the clarity of a leap of 10 to 30 times!. .


While the video compression technology progress, to benefit from the DVD, HDTV, satellite TV, high definition (HD), set-top boxes, Internet video streaming, HD camcorders, digital cameras and video CD Library (video jukebox), high-end monitors (LCD, PDP, DLP) and individual camera, and other entertainment applications.


Video compression is all exciting, new video products, an important driving force. Compression - decompression (codec) algorithm for digital video storage and transmission. .


Let's take a look at the request of the original video, standard definition NTSC digital video is generally rate of 30 frames per second, with 4: 2: 2 YcrCb and 720, it requires more than 165Mbps data rate. Save 90 minutes of video need 110GB space, or more than the standard DVD-R storage capacity of 25 times. This requirement is evident as it is now a huge amount of hard drive capacity cannot meet, not to mention more bottlenecks from the network to download the poor speed.


Therefore, video compression is the inevitable trend of popular video, but the type of video compression technology is also very high. How to choose the video compression technology, content providers and end users become the biggest problem. Because it involves more problems inside, whether content providers or end users will care about the picture quality / bitrate compression ratio. In the content provider side, have to care about the cost of patent rights payments, although it did not support the concern of our customers, but often determine our end users can use to video compression technology, the most important point.In addition, end users are concerned about the cost of compiling/decoder, which includes uses system memory, CPU usage, system power consumption, and so, after all, when you are compiling/decoding spent cost have to pay directly by the end-user.


The technical definition video codec has two standards bodies. International Telecommunication Union (ITU) is committed to telecom applications, has been developed for low bit rate video telephony H. .26 X standards, including H. .261, H. .262, H. .263 And H. H.264; International Organization for Standardization (ISO) aimed at consumer applications, has been defined for the MPEG moving image compression standard. MPEG standards, including MPEG1, MPEG2 and MPEG4. .


ITU and MPEG standards development process.


In addition to the development of ITU and ISO industry standards, it also appeared in several dedicated Internet streaming media applications, the popular proprietary solutions, including Real Networks Real Video (RV10), Microsoft Windows Media Video 9 (WMV9) Series , ON2 VP6, and Nancy. Because the content in these formats are widely used, so proprietary codec technology can become the industry standard.In September 2003, the Microsoft Corporation to movie and Television Engineers (SMPTE) proposed that the Agency's support for WMV9 bit-stream and syntax of standardization. The proposal was accepted, and now the WMV9 has been standardized as VC-1 SMPTE.


Page 7: H. H.264 is MPEG4? The difference between them? . .


Here explain why H .264 somebody! is called MPEG4-AVC, MPEG series of standards ISO/IEC belonging to, but on the other hand, to the development of international communication standards-based agency: ITU-T, H. .263 (for video conferencing, streaming video standard) embarked on a more advanced H. .. 264 development, and new development with ISO / IEC body with hand in hand, set up jointly by the two organizations called JVT (Joint Video Team) of the joint working group to MPEG-4 technology as the basis for more appropriate for video conferencing (Video Conference) the use of derivative development, but also because it is jointly developed, so called ITU-T side H. .264, in ISO/IEC MPEG aspect called MPEG-4 Part 10 (part 10, also known as ISO/IEC 14496-10), Part 10 MPEG-4 another surrogate is MPEG-4 AVC (Advanced Video Coding, advanced video coding), more than one name is actually a means, i.e. H. .264 = MPEG-4 Part 10 = ISO/IEC 14496-10 = MPEG-4 AVC.


Then, H. H.264 and MPEG-4 in the end what is the difference? More precisely, MPEG-4 Part 10 and MPEG-4 Part 2 What is the difference? Why the need to customize the MPEG-4 Part 10 do? Directly follow the MPEG-4 Part 2 Do not? . .


Although the transfer has been made against Internet MPEG-4 provides higher than MPEG-2 video compression efficiency, more flexible and elastic change playback sampling rate, but video conferencing is always want greater compression, so we need a .264 H..


In the end H. H.264 Fortunately, what? Allow us to MPEG-2, MPEG-4 (MPEG-4 Part 2), H. .264 (MPEG-4 AVC, MPEG-4 Part 10) for resolution of the three performance compared with the use of bandwidth, both MPEG-2, MPEG-4, H. .264, three from da 1920 × 1080i (non-interlaced) HDTV (High Definition, HD), 24fps (update 24 picture), picture quality, but on transmission bandwidth need 12 ~ MPEG-2 20Mbps, H .264 as long as 7 ~! 8Mbps, and is somewhere between both MPEG-4, more directly to our bandwidth MPEG-2 is used as the benchmark of 100%, up to the same effect MPEG-4 to just 60% of the bandwidth, H. .. 264 is as low as 40%, about the original MPEG-2 1 / 2 to 1 / 3. .


It is worth mentioning H .264 standard adopted. entropy decoding has two kinds: one is based on content-Adaptive variable length coding (CAVLC) and unification of variable length coding (CAVLC) combined with a content-based Adaptive binary arithmetic coding (CABAC). CAVLC and CABAC according to Pro blocks the current block of code in order to achieve better coding efficiency. CABAC than CAVLC compression efficiency is high, in the case of a picture can save 20 percent of the bandwidth, but is more complex.


Page 8: VC-1-Microsoft's hegemony. .


Why is the MPEG-4 cannot provide such a high compression ratio? in this regard is the recent increase in compression technology, more important, in fact, in recent years, the video/system processor has been the rapid development of their processing capacity has been greatly enhanced, so that you can use a higher compression ratio without having to worry about overloading the system. While VC-1 (VC means Video Codec) is derived from the birth of Windows Media, which is the provision of online music and video subscription services and the main video stream format.


Microsoft launched the 2002 Windows Media Video 9 Series codecs, video compression efficiency achieved significantly improved. WMV9 is also in the SMPTE VC-1, as implemented in the standard. Of course, VC-1 is simply a video compression algorithm, and not WMV in digital rights management, metadata, playlists, and user interface to these elements. .


.264 with H., and it contains many similar advanced coding tools, but the types differ. In addition to supporting half pixel bilinear interpolation, WMV9 for ME also allows 1/4 pixel bicubic.


Ring solution block filter (deblockking fliter) open or display, the picture shows off the next picture shows open. Evident on the map blocks of color is very serious, but under the plan the transition very smooth. After filtering, reducing the block effect, while the image quality is nearly unchanged, so subjective quality greatly improved. If you do not filter, the same subjective quality, needs more 5% to 10% of the rate. Upper and lower filter block diagram shows the effect of, we can see H. .264/VC-1 A unique video compression technology (MPEG4 PART2 solution with late block filter)..


Page 9: detailed specifications for various encoding..


In the interest payment, MPEG2 as very mature, so the charges are collected in the least, tend to no cost. This is also why many have BD / HDDVD still use the old MPEG2, of course, this and MPEG2 hardware requirements on the system there is a certain relationship between lower. .


While the initial authorization plan for MPEG4, if TV content operators to MPEG-4 format broadcast, pay per minute to $ 0. .000333, or is an annual charge for each rating user. $ .25 0, this will no doubt promote the MPEG4 much resistance. This programme, Apple, On2, manufacturers in the industry, now even the original Apple QuickTime in built-in MPEG-4 support, but also because the authorization object and delay the release date.


H. H.264 licensing fees are relatively reasonable, because H. H.264 MPEG-4 came later, and both locate close to being the case, H. H.264 only in licensing fees on the lower position, looking forward to a more generous way to fight the mandate was adopted, which is on the operator's appetite, had a number of operators on the MPEG-4 license deeply offensive, and then also enthusiastic support of H. H.264. .


Whereas the authorization fee VC-1 so early, and .264 H.. However, due to Microsoft's implementation of the strategy, the authorized source VC-1 only one authorized price and method of adjustment, as well as subsequent versions of the improvement by Microsoft on the one hand, there's no one around, despite price comparison relaxed when one knows what Microsoft is willing to increase the price, it is also a large number of operators have the most to worry about a thing.


P. 10: the end-user interest which encoding? . .


Next is our end users care most decoding spent system has, of course, this will have in the US after more detailed testing.


Nature is the most stringent requirements MPEG2 video encoding, not only that, thanks to DVD, thanks to mature for many years, the mainstream of earlier and existing hardware can be more or less the ability to provide hardware acceleration of MPEG2. Although to date there is no comparison MPEG4 video acceleration hardware for the birth, but their loss is relatively low hardware one of the reasons. .


And H .264 main grades are. ' most demanding video technology, recently more and more high code rates and 1080P, the combination of its hardware loss has reached a new peak. While the basic grades provides a relative reduction in the loss of the hardware.


Microsoft VC-1 or due to stratification of skill over the years, in slightly stronger than H. .264 CALVC basic grades of quality, while the hardware resource requirements are still again lowered. On the whole, VC-1 is best for the end user's code, it has a very good quality at the same time, the hardware requirements relatively low. Bear online www. . Beareyes. . Com. . Cn. .


I go to the online forum, see hit such a vote on whether it is necessary to H. recoding .264/VC-1 posts for MPEG2, resulting in more than half of the people is supported. On picture quality and compression ratio, of course not and MPEG2/H .264 VC1., but its relatively low on hardware requirements, have resulted in the majority of users abandon the picture quality/compression ratio, select MPEG2. Of course, this is only a Nianchu in February when the vote, now since Xinyi Dai Du Jubei the video graphics acceleration, the situation has been an effective relief, I believe in the near future, no one worried about a further Jie Ma HDTV Er the. .


The following is a video compression technology to independent knitting/decoder frequency requirements, this forms a good quantitative representation of the video compression technology and hardware requirements.


In the video decoder context-specific acceleration, PC cards on the most recent, PUREVIDEO HD and AVIVO HD can support H. Full decoding H.264, and VC-1 aspect, PUREVIDEO HD only supports dynamic compensation and DEBLOCK decoding, VLC stream for processing and inversion, or only to the CPU to go for. .


In addition, the ones on the Internet, some HDRIP (HDTV encoding package again) majority of ones, using X264 X264 H .264 based. open source codec with high .264 H. compression ratio as well as on hardware has set higher demand, however due to its relatively low rate in General, so the burden on the system is very rare to direct embodiment. In addition there is a small part is used to compress the MPEG4-XVID, XVID is difficult to guarantee quality, FPS, and resolution of cases, the volume control in the capacity of 1 piece of D5 (4. .3G).

Finally, let's balance all factors, look at all the mainstream HDTV video acceleration technology concept analysis, there is no doubt that H .264 and very VC-1. has the potential to become the mainstream in the future, of course, our self-developed AVS also H .264, and. VC-1 tongtaijingji, who is the winner, it's not to say.


P. 11: Bowl a good or a large pot? Package format Xiang Jie-AVI. .


The so-called encapsulation format is already encoded compressed video and audio track in accordance with a certain format into a file, that is just a shell, or we think of it as a video track and the audio track of a folder can also.


Popular parlance, point, video track is equivalent to rice, while the audio track is equivalent to food, packaging format is a bowl or a pot, used food containers in full bloom. Some people may feel strange, containers, not food on the line can bloom Why, with a bowl on it, why work out so many formats and Practice? . .


Fact, imagine, there are dishes, such as ribs, relatively large, Bowl, pot was changed. A comparison of hot food, and also cannot be placed in a plastic container, of course, there are certain personal preferences. Therefore, the basic container selection lies in the fact that their video/audio compatibility, as well as the appropriate scope. We should understand that many people have always regarded encapsulation format as described in the previous video encoding, but the two are not necessarily directly.


AVI container - mature and old technology. .


AVI is Microsoft in 1992 for the fight against Apple Quicktime technology, despite the international academic community recognized AVI already belongs to be eliminated by technology, but because windows of versatility, and easy-to-developer API, is also widely used.


AVI file structure, divided into head, body, and an index of three parts. . The body of the image data and sound data is stored interactions. Index from the tail index can jump to put their own position. .


AVI itself only provides such a framework, internal image data and voice with according to the format can be any of the coding form. Because the index is placed in the tail of the file, so seeding internet streaming is impossible. A very simple example, download films, if not the download is complete, it is very difficult to play out.


Another problem is the high bit-rate VBR audio AVI file support not good. VBR stands for Variable BitRate, is the dynamic bit rate can be defined according to the current needs of different bit rates, avoiding waste and improve efficiency.With it came also, because the vessel's image and sound are separated, so playback requires an image and sound synchronization, if the words because the CBR audio bit rate is a fixed value, the synchronization does not become a problem, but it is constant VBR audio in AVI conversion, but does not have a timestamp to VBR audio and image, the image of sound out of sync problems.


VirtualDub then proposed a new approach extends to the VBR audio AVI compatible, but the high rate of data loss when problems arise, leading to harmful sounds, this problem up to now no more perfect solution. And even more regrettable is that for TrueHD, DTS-HD audio, etc. is not acceptable. .


Page 12: Bowl or pot? packaging format Pro-TS.


Introduced earlier struggle between HDDVD and BD, although the two are unified in the coding used MPEG2/VC-1/H. H.264 can be there by the bifurcation package format. DVD Forum officially recognized HDDVD using PS package, that is, Program Stream (program flow), and before this DVD MPEG2 Program Stream used in the same package, PS stream suffix name is VOB and EVO so.While BD in the absence of official DVD Forum certification, PS package instead of another package MPEG2 TS encapsulation, i.e. Transport Stream (transport stream), TS suffix to TS. They are part of the MPEG2 system two different grammatical structure, and now only as a package. TS for PS flow easier to transport, but also because of its nature, is more error-prone, so in the previous General storage areas is using PS streams, of course, now with the fault-tolerant/correction technology to increase the scope of application, TS has become an increasingly widespread.


Most popular now online package of HDTV remux to TS version, PS can only HDDVD original package only to see, so let's focus on analysis of the TS package format. .


TV programmes at any time you are able to open television decode (watch), so that the characteristics of MPEG2-TS format is required from any fragment of the video stream is available separately for decoding. From a structural point of view, the TS is composed of header and body formed by the expansion of TS also includes a timestamp. So no matter what the format of the VBR audio track, it is easy to pass the time stamp to synchronize images. Of course, the new sound formats, require a new separator, the decoder to decode. Currently in the development of continuous improvement.


Unlike TS AVI, from the birth of that day, on account of the network play, and I quickly became the world standard and widely used in digital broadcast television, mobile phones and other fields. .

Page 13: Bowl or pot? packaging Exposition-MKV format.


In addition to REMUX versions, (Remux mean is non-destructive extraction of the HD-DVD and BluRay-DVD inside the video data and audio data, packaged in the familiar TS or AVI file), many HDRIP (re-encoding, that is, After the film had lossy compression) is generally used in packaging formats AVI, MKV and MOV. Nature does not need AVI package introduced, MOV is the Quicktime package, the package, and AVI is almost the same time, quite a few flaws, is now rarely used. .


Matroska MKV is the use of the abbreviation, it is a new multimedia package format, the more common collocations is X264 + MKV.


MKV package is very new, but also very open, which compared the advantages of AVI in the following points:. .


1: variable frame rate: this needs to be encoded, imagine slow playback changes (such as still life) to compare low FPS in place, you can save a lot of resources.


2: Error Detection and Repair: This is undoubtedly provide error correction and fault tolerance, especially in the network transmission needs of today. .


3: soft subtitles: often look DVDrip HDrip friends and learned that subtitles are generally to other file formats, MKV, it can be embedded in the packaging, but will not be confused with video, or you can choose multiple subtitles. This makes it easier to transfer saved.


4: streaming: This is basically the same reasons TS stream, through the time stamp to manage video and audio synchronization problems, to do that is to see the next. .


5: menu: interactive action makes MKV more humane.


6: Powerful Compatibility: MKV greatest feature is the ability to accommodate many different types of encoded video, audio and subtitle streams, even if it is very closed it RealMedia and QuickTime are also included, and called universal media container. .


7: open and cross-platform: use of Matroska is an open architecture that has many advanced features, and cross-platform use.


However Matroska us relative to the shortcomings of the above is obvious, it can not rely on deep background, which determines it can not make a difference in the business field. However, we can see from the DVDrip is not in the standard is the only truly advanced technology in the standardization of commercial road met a lot of non-technical barriers, while the Internet is concerned, there is no such concerns as, so you can line MKV Quick popular. .


However the disadvantage of MKV is obvious, separator, better only HAALI splitter, coupled with the civil standard, it is very difficult for us to a place other than a PC can see it's there.


P. 14: What is HTPC. .


What is a HTPC.


HTPC Home Theater Personal Computer is the English abbreviation is "home theater PC" means. In short, it is a special focus on multimedia personal computers. .


HTPC and the main difference between an ordinary PC is that it is not in pursuit of high performance for the only goal, it should look and feel, performance, noise, power consumption 4 ' balanced products.


HTPC should be placed in the living room, as a family of digital audio-visual center. On the living room on things like TV, DVD, stereo, amplifier, as it must have a pleasant appearance, who wants to see in the elegant living room an ugly chassis. It is not too big, either aesthetically or from the space-saving point of view, it is very important to a case such as the tractor is a brake general landscape. .


Our performance and requirements, but to make use of the dual-core CPU, or a video card with hardware acceleration, so since it is faced with the high bit-rate of H as a leisurely .264., and encoding (recording TV) duo also effectively. Hard drive is a very critical factor, personally think that is the starting point, 320G better.


Function, the board as much choice with more interfaces, 1394, and SPDIF IN / OUT are needed, and graphics cards have DVI / HDMI, S-VIDEO / color. Optical storage to DVD burner is better. .


Noise is a very important factor, after all, who are not willing to enjoy audio and video while also enjoying some noise and low noise of the Board, as well as low noise level of your hard disk and optical drive is particularly important. Board ideal is a passive cooling without fan speed, even if it is low for a long time after the same will issue some color noise, clean or replace the problem not solved, but passive cooling is not such a problem.


Power consumption is also extremely concerned about HTPC a factor to consider first of all from the energy-saving home theater applications may be a long boot, power consumption on behalf of saving electricity. The HTPC also limit the size of a box, especially the alignment system in the use of Micro ATX's also only use half-height card, so imagine the volume, heat becomes a big problem, if the great power of accessories may not be able cooling Therefore, mainly as far as low power consumption. .


Page 15: the importance of a DVI HDMI: simply cannot replace.


First of all, most people should know the characteristics of DVI and HDMI are the largest numbers, and as such, many people simply think that, HDMI is only with the audio capabilities of DVI, both in the video is exactly the same. .


In fact, this is totally wrong. If only this is the case, we have the audio and DVI cables together without so many manufacturers spent so much effort, consuming so much time to make the standard:).


From the above we can see, HDMI and DVI are based on the number of T. . M. . D. . S signal connection. Have adopted the digital signal advantage is that Zai conversion and compared to facilitate non-destructive and do not represent Jianrong, Jiu Xiang RAR and ZIP compression formats that can be translated very easy, and Wu Sun, but they are using the format, data Cunchufangshi completely different, very simple example is the only software designed for the ZIP there is no way to read the RAR package, such as WINZIP. .


HDMI EDID data transmission in the CEA will contain a VSDB signal which blocks there to verify that the determination of whether the receiving end is also the HDMI device data values. When verifying each other is also the HDMI end will HDMI standard format to send the signal; and validate each other as DVI device will use the DVI specification in the form of numerical data, to send a video without audio data.


From this standpoint, HDMI is fully backward compatible with DVI, HDMI is the interface transmitter, and DVI transmitter interface for the receiver are DVI interface case, both using the DVI data transfer protocol , at this point is exactly the same. .


HDMI Vendor Specific Data Block validation so indicate.


It can convert HDMI and DVI? In fact the market has already emerged in many of DVI and HDMI switch Mutual Convert between adapter and cable. .


As we mentioned before, the beginning of the HDMI in transport will have a verification process to distinguish whether the devices determine signal HDMI the DVI specification, but there is no such a step, so no matter what interface DVI connection cable transmission of what remains of the DVI specification. These adapters work?.


DVI HDMI switch to natural Needless to say the, HDMI is fully backward compatible to DVI. The DVI switch to HDMI it. In fact as is by T. . M. . D. . S digital signal transmission, so follow the same electrical specifications, basically adapter / switch wiring just lead angle to change the physical signal transmission is still the DVI signal.So, for a computer monitor or digital television, flat section also does not matter, because these devices can directly access DVI signals, but if you come across some early HDMI TV and recording devices, this can have some compatibility issues, for example, does not properly display its contents-black screen, etc..


Now most of the TV DVI signal at the access problems still exist large and small, for example, does not correspond to the corners, can not maximize the screen, the screen flashes, can not be achieved point to point, does not recognize the signal and other compatibility issues, this Winnie the evaluation room even in the evaluation of recent FULL HD flat-panel TVs have encountered this kind of problem, but there are some issues can be minor adjustments in the PC side can be resolved, while others have no solution. HDMI in the graphics card replaced after they meet the HDMI 1. .2 Standard television and computer can be connected correctly. .


Summary we mentioned above, in the signal transfer format, compatible with DVI HDMI can be good, but HDMI DVI interface conversion requires access equipment on the support of DVI signal transmission, from this point on, HDMI is the perfect interface.


Page 16: HDMI importance of the two: to prevent the loss of gray-scale signal. .


We speak on the article merely electrical signal specifications, but here we have to talk about the specific content of the transmission-gray signal. Even if you can access the Platform TV DVI signal and recognition, but as long as it is not for the PC conversion of the gray-scale signal, since all the screen displays properly, but we can see the screen brightness and dark detail still severely distorted. What's happening? HDMI and DVI although it follows the same electrical specifications, using .M T.. .D. S digital signal transmission, but the biggest difference is that, DVI is the standard PC, while HDMI uses most of the appliances in the field. .


The different application fields can also cause specifications vary, the general use of the PC Full Range RGB gray, gray-scale value range is 0 to 255; for these appliances and consumer electronics uses the RGB levels are Limited Range, numeric range is 16-235, the 16-235 is a continuation of analogue television format.


HDMI DVI switch treatment in the absence of gray-scale flat-panel TVs will directly lead to 13% on the gray scale signal loss. The HDMI can be processed for the color difference signals can also be a RPG Limited Range of Full Range, the sender will generally adaptive. .


13% of the gray-scale loss of signal.


Normally, high shadow detail visible light. .


Page 17: the importance of three HDMI: relative to the improvement and upgrading of DVI.


Why should I improve and upgrade relatively DVI on the last side to say? Because the characteristics of these upgrades, Zai this is not a necessary, in other words, no more missing Ye event, at least not as the previous two years of Zhijie affect normal use. .


Subject to positive and continue to talk about the improvements of HDMI.


1: HDMI can transmit both digital audio and video lossless, while DVI only supports video output. .


PC on HDMI output audio and video at the same time, there are two ways.


1: internal connections, show the same chip and audio chip in a PCB, the sound card directly through the PCB traces on the signal transmission to the graphics card, and then integrated into HDMI signal output. Examples include the integrated graphics, such as MCP68, there are some cards with integrated audio processing chips, such as the R600. .


2: an external connection. Display chip and sound chip is not in the same piece of PCB, through the external wired connection. Generally it is the sound card directly using the video OUT to connect SPIDF, but also has a dedicated HDMI audio connector, a growing number of motherboard and a sound card in use (below).


1080P HDMI can transmit video signals at the same time, but also to 192kHz sampling frequency of 8-channel audio signal transmission, and all this in only one connection to complete! According to statistics, an HDMI connection can replace 10 ~ 20 analog transmission line, which greatly simplify the wire bureau. .


2: HDMI can use 3 TMDS channel to transmit video and audio, DVI only two. Normally, a TMDS channel can reach the operating frequency and 165MHz 10-bit interface, you can provide 1. .65Gbps bandwidth so that to have 3 .3Gbps DVI. bandwidth and bandwidth HDMI near 5Gbps. In HDMI 1. 3 TMDS was enacted after the 165MH frequency raised to 340MHz, improve by about 2 times, so that the horrors of HDMI can provide 10Gbps bandwidth, and also dual-link specifications can be used to further increase the bandwidth to 680MHz. This is very concerned for the future development potential. .


3: existing HDMI 1. .1 and .2 version 1. and DVI is only able to support the 24bit color depth 1. .5 version of HDMI is greatly expanded to 30-bit, 36-bit and 48-bit (RGB or YCbCr) with output capacity of more than 100 million colors, and a substantial increase in the levels of contrast. While HDMI 1. .3 standard can support a new generation of "xvYCC color space, known as" with the current color space specification of 1 .8 times color signals. output capability. HDMI LLC chairman, said Leslie Chard, ATi and nVIDIA GPU which can be easily integrated in the new norms, Sony PS3 already supports "Deep Color". In fact, the Blu-ray and HD-DVD standard support "Deep Color", but both sides have not announced support for HDMI 1. .3. .


4: transmission distance: without affecting picture quality, transmission distance of HDMI can reach 15 meters, and DVI is less than 8 metres. For the purposes of this PC is not very useful, but for home appliances, relaxed restrictions will line greatly reduce routing.


Optical fiber transmission, the wire ends joined the optical signal converter of the HDMI signal up to 100 meters. .


Page 18: AVIVO HD and PUREVIDEO HD technology comparison (part one).


A new generation of coding H. .264/VC-1 Codec program process includes the following five components: precision motion estimation and intra estimation (Estimation), transform (Transform) and inverse transform, quantization (Quantization) and inverse quantization, loop filter ( Loop Filter), entropy decoding (Entropy Coding). The figure is H. H.264 coded flow chart. .


AMD last generation Radeon ATI graphics hardware support X1000 AVIVO technology for H .264 with encoding VC-1. video Bitstream by CPU processor responsible for Processing (processing) and Entropy Decode (entropy decoding), a Shader rendering unit hardware acceleration Transform Frequency (frequency conversion), Pixel Prediction (pixel prediction) and Deblocking (rings for block filter) process. Therefore, decoding can not be said to be a pure hardware. .


Page 19: AVIVO HD and PUREVIDEO HD technology comparison (below).


You can see, AMD last generation high-definition video hardware decoding technology is not perfect, to the HD 2000 series, Radeon HD 2600 series (RV630), Radeon HD 2400 series (RV610) graphics chip which integrates the hardware unit dedicated UVD (Universal Video Decoder device), be fully responsible for hardware acceleration Bitstream Processing (code stream) and Entropy Decode (entropy decoding), the coloring unit for hardware acceleration Shader Frequency Transform (frequency conversion), Pixel Prediction (pixels forecast) and Deblocking (ring block solution filter) process, that is, Avivo HD。.


NVIDIA GeForce 6 times as early as the introduction of HD video on the starting solution-PureVideo, hardware acceleration, in fact, is by its theory-driven use of programmable GPU's idle computing power of the coding speed, in fact, this is not a complete hardware decoding, a considerable a majority of GPU software to complete, but no matter how large degree of sharing of the CPU pressure. And the quality is also a certain change. .


The former generation PureVideo is only one of the hardware components of the VP (video processor, the Video Processcor) and the VP of processing power, and performance is relatively low. The GPU NVIDIA G84, not only with a more powerful new video processor, and an additional entropy decoding processor engine, NVIDIA called BSP ENGINE (Bitstream Processcor ENGINE). New video processor (NEW VP or VP2) can be MPEG-2, VC-1, H. H.264 decode in real time, including the recently popular third-generation video coding. The Bitstream Processcor ENGINE H264 mainly for the CABAC / CAVLC entropy coding to decode both. .


Said before H .264 standard adopted. entropy decoding has two kinds: one is based on content-Adaptive variable length coding (CAVLC) and unification of variable length coding (CAVLC) combined with a content-based Adaptive binary arithmetic coding (CABAC), which is the primary grades. CAVLC and CABAC according to Pro blocks the current block of code in order to achieve better coding efficiency. CABAC CAVLC compression ratio, high efficiency, but is more complex, the hardware requirements will be higher. CABAC (CAVLC also) is a lossless encoding will not damage the screen, but will reduce the speed of encoding and decoding. .


Initial glance PUREVIDEO HD AVIVO HD to have full hardware decoding functions, in fact, two in support of the video encoding, there are some discrepancies.


The first is two pairs of MPEG2 video acceleration is not the full hardware decoding, to a considerable part of the CPU to the soft extract, this point not think many people will disagree, after all, MPEG2 hardware loss itself is very low, then by some hardware decoding, the CPU occupancy rate has been reduced quite a low point, which we later tests also confirmed. .


The considerable damage H .264 resources. encoding two also adopts unified attitude, full hardware decoding, complete liberation CPU bottlenecks, which makes H .264 in two. "new video decoding is no longer a problem.


In addition, the VC-1, ATI / AMD, and NVIDIA's attitude was the difference. ATI / AMD that, VC-1 a and H. A new generation of HDTV standard H.264 encoding, while there is relatively high CPU utilization, so still using and H. .264 full VC-1 decoding like (this is why so many transistors 2600xt integrated one of the reasons); and NVIDIA is considered, although the consuming VC-1 is relatively high, but after some decoding, low CPU is still capable of decoding, as well as the CPU frequency, this situation can be alleviated. In addition NVIDIA also believe that even if the software solution is also the mainstream CPU only 70% of the CPU occupancy, plus part of PUREVIDEO HD share is only about 40% after the occupation, not to other major task in the case, and 0% CPU occupancy no difference. .


This point is the benevolent see benevolence wise see Moses, according to the author's personal views, all hard decoding in the future will be replaced by the soft decoding, and now I even decode CABAC 40m code rates when using pieces of original soft decoder, in order to guarantee quality and you can always change the decoder; on the other hand, are better than nothing, which day I hadn't had the Conroe 3. .6G, use a Athlon64 3000 +, with a total of H264 decoding VC-1 and AVIVO HD is clearly better.


P. 20: decoder, splitter, and DXVA concept. .


We introduce DXVA decoder, separator and the concepts.


Decoder function is on video or audio decompression. We know that both the original raw video or audio, data are very impressive and huge, so we use the encoder be compressed, so that it can help transport and storage. In the playback screen we will need to restore or sound, which requires decompression, that is decoding. Which more complex video decoder:. .


Video compression technologies like we said before, there are several, each room also has a number of official and third-party codec, decoder features screen, there are differences in speed, but is generally divided into two types of codecs: hardware decoder and software decoder.


Hardware decoder is to use decoder interface and brought the drive to connect the hardware itself, using the function carried by the video hardware decoding, it reduces the load on the CPU in order to achieve smooth playback and multitasking ability to upgrade CPU. .


Software decoder is in addition to hardware decoder, the decoder, its greatest features is the use of CPU processing functions for General, software decoding. Software decoding although the consuming CPU, but you can modify, upgrade, CPU resource information is the best choice.


Separator function is to package together to restore the video and audio out. Before we talked about a number of packages, each package must correspond to a separator to the right to separate video and audio decoder for decoding. .


Separator for many, it is generally a non-standard packaging format with a regular player will not have the appropriate separator, such as MKV. And separator famouser Moonlight haali splitter, etc..


DXVA (also known as DirectX VA) is the full name of the DirectX Video Acceleration (hardware video acceleration interface). .


DXVA is a Microsoft and graphics chip manufacturers jointly define a hardware interface specification. If a graphics chip DXVA on hardware specification, does not mean that it enables DXVA it defines all of the features. But to be sure: for DXVA define each of the features that meet the specifications for display chip DXVA driver will tell the system, this feature in its hardware realized or unrealized — this is DXVA specification mandatory requirements. The advantage is that the application does not need to spend time and effort to test the video card is not a function . .


Similarly, if a decoder DXVA specification, nor is it able to take advantage of all the inside DXVA specification combination of features, it can choose to have the ability to support themselves, or want to support a combination of those features, and other functions may be waived.


In addition, if a show that support through the driver chip though some features, but decoding device Renwei the chips support this feature is unstable, make the system crash or wrong, then the decoder can also stop using the chip of this kinds of functions. .


In accordance with DXVA hardware decode acceleration, has three levels.


1, MC acceleration (motion compensation, also previously referred to Pixel Prediction). .


2, IDCT Acceleration (earlier Frequency Transform) + MC acceleration.


3, VLD acceleration (previously referred to the entropy decoding) + IDCT + MC accelerated speed + (deblocking fliter solution ring block filter). .


In addition to the older graphics card (such as Geforce3) MC acceleration is supported, now GF6/7, X1000 series II, GF 8600/H .264 8500 supported. accelerate the third grade, as well as the HD2000 series support/H .264 VC-1. at the third level of acceleration, of course, this also needs to be called the decoder supports.


When the player or the decoder display DXVA (also known as DirectX VA), also represents the hardware acceleration has been opened. .


All in all, set playback software is the most simple and direct open hardware decoding software can only be a PowerDVD. It can be said that PowerDVD is the best software to extract VCD/DVD/HDTV playback tools, but it comes with hardware-accelerated encoding HDTV, making the call is extremely simple.


If you are using a NVIDIA graphics card and with PUREVIDEO technology, it will have a PUREVIDEO HD logo is displayed. .


Can PowerDVD respectively. H .264, VC-1, MPEG2, DVIX, XVID X264, etc, formats. That is basically a mainstream DVD/HDTV/DVDrip, HDrip can decode and display functionality with hard solution without any settings to open the hard solution.


The following information on behalf of DXVA hardware acceleration enabled. .


PowerDVD is a powerful and easy to use, very suitable for the newbie read hard solutions, even the soft solution, it can most rapidly find positive solutions to a decoder that does not appear on the screen, the audio is not correct, all without setting. By the way, why should we speak Chinese films, because in addition to your foreign languages in particular, PowerDVD is no way for external subtitles, this is the software for a great pity, because so many people abandoned the PowerDVD, but simply use it as a decoder with other players.


PowerDVD shortcomings Moreover, because no configuration, the separator relatively small, even too old to die AVI package that separation may have some problems, of course, and now the AVI HDTV a dts package may be some relationship between multi-track . Elsewhere, despite the PowerDVD DVD playback is started by, but if you encounter a HDDVD's the same for MPEG-2 PS package EVO file, PowerDVD as it is impossible to separate. .


PowerDVD benefits: no need to set up, there are many at the same time there are different levels of acceleration of decoder that is open, it is very convenient, is buying HDDVD/BD disc the best player.


PowerDVD shortcomings: PowerDVD on the Internet to download the Remux source of non-TS-chip package can not be properly separated, if met HDrip the MKV format is no alternative. The most angry is not linked to any subtitles. .


Note: PowerDVD must take precedence over any other player installed. If PowerDVD not working properly, it may be decoders/separator confusion, reloading can generally be resolve the problem.


P. 22: the ultimate decoding, and decoding the perfect setup guide (above). .


Ultimate decoding as well as perfect decoding in fact that is a big collection of software, which nowadays is the most popular include player, decoders, as well as the separator. As the ultimate decoding or perfect decoding settings very bossy, and freedom is not high, so we can make the ultimate decoding or perfect decoding as a decoder and separator package to install. That is only used with decoder or separator, or even the player, but not use it's own settings, but instead uses the settings most meticulous KMPlayer.





P. 23: the ultimate decoding, and decoding the perfect setup guide (below). .


Here we explain, whether installed ultimate decoding or perfect decoding, the system of the decoder and the separator is determined by the current settings, for example, you now want to use the NVIDIA VIDEO Decoder, you will need to select the corresponding to the NVIDIA VIDEO Decoder options and application, it will bring up NVIDIA VIDEO Decoder installed.


Similarly, the need to tune out what kind of decoder, or separator, directly in the ultimate decoding, or decoding the perfect setting, it will be installed on the. .


As can be seen already can use search to NVIDIA KMPlayer VIDEO Decoder, the decoder is in.


Another point to draw attention, generally best not to use the ultimate decoding, or decoding on the KMPlayer perfect setting, our grounds are KMPlyaer more powerful set. But the ultimate decoding, or decoding a perfect set of high-priority, very high-handed, set the KMPlayer's options, then set the basic KMPlayer invalid, so we recommend this set:. .


In addition, installation or already have KMPlayer KMPlayer green miananzhuangban, we in the ultimate decoding or perfect decoding options: call this.


Doing so we can perfect the ultimate decoding, or decoding the default player is set to Media Player Classic, KMPlayer will not only have a direct impact, but also provides a decoder / splitter at the same time, but also more of a Media Player Classic plays election player, achieving three. .


Page 24: KMPlayer Player Setup Guide (part I).


First of all, I want to recommend something KMPlayer player, as I know there are still a lot of friends use MYMPC, storm and wind and thunder audio video, most people always think that the software easier. In fact is not true, KMPlayer default settings as can play audio and video files in various formats, and it has many shortcut keys, can display size, length and width ratio of free to control the color, the most important of its separator is relatively excellent 既然is RMVB / RM fast-forward or backward, almost no hysteresis and delay, which is the normal player can not do. .


Korean audio player KMPlayer, Almighty and Mplayer from linux ported to the Kmplayer (KMP) nearly all on your system to play audio files. Through a variety of plug-ins extend the KMP can support the emerging new format.


The player device is boundless and high maximum benefits, how settings are as, or even to the streaming media depending on the Fen Li formatting different devices, according to different encoding format set different 解码 device that is what we most need a high definition broadcast li function. .


However the disadvantage is obvious, that is why before we are going to keep duplicate declaration PowerDVD straightforward, it is because of the relative terms too easily KMPlayer, KMPlayer is set-too complicated.


We are all in this step by step how to set up the church KMPlayer, and tell it the meaning of each step. .


First enter the KMPlayer parameter options, we need to do first is to make the decoder and separator settings used unconditionally.


Then we have to cancel all of the default built-in decoder, use our custom decoder. Can not select all options. .


In the select an external video codec, the original is in addition to the default .dll by libcodec. no other process can call, so we want to use a custom decoder to search the current system of all decoder.


As installed before the final decoding or decoding such a perfect package, containing a variety within the system decoder / splitter, just click search and you can add all of the registered decoder / splitter all find out. .


Page 25: KMPlayer Player Setup Guide (below).


Then we have to define what separator to use, and only have to decode the correct separation, this step is more important, its search and management of external separator method and decoder, as will not repeat it here. .


In addition, the present tense of more popular Haali splitter, you can very well on MPEG2-TS MPEG-PS and MKV and other packaging, strongly recommended. But Haali splitter is in the separator box, but KMPlayer specifically one can manage what package uses Haali splitter.


But I studied for a long time found in here to manage Haali splitter might not be effective, and direct the installation of Haali splitter is perfectly safe when directly selected. .


How do I know if Haali splitter function? in addition to viewing the KMPlayer-RI, the simplest method is called regardless of any player Haali splitter, it will appear in the lower-right corner of an icon, this indicates that the call has been properly.


How to determine where you are now in the KMPlayer with the kind of separator, which decode it? Following operation, we see the use of the video decoder is the PowerDVD 7. . X of H. H.264 decoder and audio decoder is adopted InterVideo Audio Decoder, because Haali splitter is not in the list of KMPlayer support within, so it is not shown, such as the above method, we can see the desktop lower right corner of the bar it. .


Below we will start to describes how to set the KMPlayer for hard-coded to open solutions.


P. 26: KMPlayer player set H. H.264 hardware solution guide. .


H .264 decoding set relative. easy, its requirements before you install PowerDVD 7. .X on h .264 decoder, concrete steps outlined above please come in. Also try not to use the built-in separator separator, sometimes called nero separator or built-in separator, even if the decoder cannot normally use, but cannot hardware acceleration.


Then select the external video decoder, if not previously transferred to an external decoder or a search through an external decoder, then all the system default, so we need to search for external decoder. .


Search external decoder this step applies all external decoder search out.


Then select the appropriate encoding format in the corresponding decoder, H. H.264 direct use PowerDVD the H. H.264 decoder can directly open the hardware acceleration. .


And then point to the right of C, you can go in and adjust to the decoder. USE the options check DxVA opens hardware acceleration.


Perfectly decoded set is relatively simple, as long as H. H.264 This is a select Cyberlink (DxVA) can. Of course, the best separator, or choose Haali. .


In addition, it is necessary to introduce this soft solutions CoreAVC. H .264 software, it is recognized and H .264 screen settings. comparisons are excellent codecs, even though it is only software operation, but lower than FFSHADOW CPU utilization, has become the preferred soft solutions decoder.


Page 27: KMPlayer player set VC-1 hardware solution guide. .


VC-1/WMV HD mixed, first of all to compare the new version of KMPlayer selection, since 2. .9. start after .3. .1288 increase VC-1/WMV HD option, KMP VC-1 hard solution is no longer a dream.


But first we have to determine is to install WMP11, or WMP11 in own decoder wmfdist-11. . Exe this file. .


This codec is installed, you can call the KMP.


But where KMP is not set on the WMVideo decoder, we have to use a setup program WMV PowerToy. . Exe set on the WMVideo decoder. .


Detailed settings are as follows, you can open the VC-1 acceleration. In the last one on the picture to open a strong deblocking and soft shades would increase the burden on some systems, but on the screen, recommended machine good friends.


The perfect set decoding is relatively simple, direct select Microsoft that WMVideo decoder. .


Then click on the right side of the configuration, the perfect decoding WMVideo decoder also integrates a Chinese language Setup:.


It is noteworthy that the ultimate decoding and VC-1 failed to provide any of the settings, so it can not be set. .


Page 28: KMPlayer player settings MPEG2 hardware solutions guide.


MPEG2 hard solution is benevolent see benevolence and the wise see wisdom, can be said that even the very old graphics card will support MPEG2 acceleration (provided that they meet DXVA standard), but most people's CPU's software solution can flow MPEG2, it would need hardware solution We see the preferences. .


MPEG2 hardware solutions for a more interesting, whether it is NVIDIA graphics or ATI or INTEL video card, you will need to call the NVIDIA Video Decoder.


KMP settings as usual. .


Press the right after the pop-up setting C, determine hardware acceleration.


In the decoder, after a successful call to its solution in the lower right of this column will appear as an icon. .


Right-click to open its properties to display its contents.


Perfect as usual decode settings or convenience, but pay attention to is to choose NVIDIA, but do not select NVIDIA (VPP), as selected NVIDIA (VPP) DVD film will be the source after the real-time IVTC rendering, image quality will improve a grade, but will also lose the hardware acceleration, this will be to note. .


Page 29: how to make sure that you have open hard Acceleration (on).


Different software have different detection methods, but no matter how open the greatest advantage of hardware acceleration is to reduce the CPU share, so we can see where the CPU utilization, for an obvious effect, one can see out, as shown below. We use Perfmon View quantitative investigation CPU utilization rate than the Windows Task Manager to view more intuitive. .


On success, the CPU utilization rate of 25%.


Not open, CPU occupancy rate of 56%. .


PowerDVD is the most simple view: view only their own video corresponding acceleration checked, and it is correct by using acceleration technology.


P. 30: How to confirm that they have open hardware acceleration (bottom). .


In a slightly more complicated in the KMP, first follow the steps below.


To ensure that hardware acceleration is turned on, we first want to check whether the decoder is being called correctly. .


We have seen almost there will show all of the information we want. First, call the filter, and then there is also information on video/audio decoder information. Here we CoreAVC video calling is the decoder instead of with a hardware solution speed. Cyblink H .264 decoder.


Decoder, after being called correctly, and the settings of the decoder correctly, the words will appear DXVA on behalf of graphics hardware acceleration is already open. No matter what new sources, as long as the DXVA hardware decoding appears to be open to representatives. .

Bond succession to the sixth generation of the starting point for the new "007" series, rumored merger of Sony MGM is one of the important reasons (of course, the old MGM film library so many classics are waiting to release DVD, is the Fatal temptation ... ...). 11 years ago, "Martin Campbell Pierce Brosnan +" and "Golden Eye", created a twilight of the transformation of action star James Bond, the British spy from a large open career, mixing in a hail of bullets, a hotbed of soft collapse. .


The Royal Casino "for" the freshman "Daniel · Craig appearance was hard, style characteristics, are not able to let him just tackling difficult, but rather to its" why not know of the merry Knight 007 "pre-primary through to depict key, pious tenderness tiehan world love tragedy. The change in result is no longer the "gentleman" intuitive feel temporary upheavals, but come to think of it not unreasonable under. Emotional, impulsive, violence — compared to England's aesthetics, but closer to the American audience preferences. Originally, the sides of the Atlantic both ways will not be easy, Campbell, director obviously intended to "encourage some Bond fans the first look," say, understand the times. .


In recent years, the secret service. Regardless of the ultimate secret of warm, Bonn, cold tones, or the diezhongdie 3 "not tune in to the direction of" realism ". Like "Robles · Bruce South and Harriet · Belle" did know, jump jump to play in modern civilization under the more pragmatic people's eyes is becoming ridiculous. On this point adjustments, through the "Casino Royale" trailer can lift the veil on clues: First, Qinghui colors, cold style, the atmosphere of suspense, The grassroots of the "Cold War" flavor, always realistic; 2, sharp Henla, simple and unpredictable, publicity wild, one by one and have shown a strong desire for violence. .


From "Zorro" series of thoroughly chic, to the vertical limit on steep rugged, high performance Director Campbell, master scheduling and big thanks to see, as a result, the Royal Casino on the transformation of nature without any problem. The smartest move more than just said goodbye to the "cold war mentality"-style return to cold war bond sense, but adjusted to counter terrorism, namely support for traditional iron, is directly contributing to some of the perennial rejected the 007 of countries and regions on the "Royal Casino arms wide open (for example, China, Khan ... ...).

Adapted from the classic Broadway musical of the same name. Chicago born black girl, travel to come to New York in search of Star dream, experienced all kinds of adventures. Be many people in the revolutionary, but I am very fond of the Oscar for best picture of the Chicago screenwriter Bill · Kang, Assembly work, positions, flagship black singer Knowles and American Idol Hudson's ACE in the hole in the big screen again weave colorful brilliant dance world.


In recent years, the black fellow in the Academy's podium increasingly proud. See "Dreamgirls" dazzling actor groups: Grammy winner Beyonce Exhibition singing, last year's Oscar winner Jamie Foxx starred in the sophistication of agents, Aidimofei decoration popular singer ... ... as if "black star party," the surprise team, is expected to perform mass Award nomination. Successful adaptation of a masterpiece, "Chicago" classic examples, it is difficult to question the "Condon made" quality; Knowles, Murphy and others, stage performances, but also called Aspect great.In the Phantom of the Opera "," rent "," producer "and after successive defeat, this luxurious contemporary masterpiece has become the only numbers from Hollywood incense.


As usual, speak out of turn two "disturbing factor." First, the director almost zero Condon resume to musicals to use, whether too high a threshold? Second, black genius of rhythm, how the visual language of performance? By Paramount acquired DreamWorks, will do little gold man's dream final gamble. I believe soon out of print, "DreamWorks" words (the issue of animation as usual), let the judges on the general care of this as a plus. .

As dual-core, like no weak U, 1080P no weak films, after all, on the resolution to how this was 10 times stronger than the DVD. But if you look at used H. .264/VC-1 Increase the rate of the 1080P HDTV outside, the look of this MPEG2 old movies, always felt had diarrhea uncomfortable, as if suddenly changed to the long term DVDrip RMVB Biequ feeling like that. Somehow, in addition to subtle, there is not much difference between the static picture, but there will be a dynamic encounter significant blocks of color, and the glitch phenomenon, even opened the IVCT can not save.This schema is no DEBLOCKING and MPEG2, coupled with low bit rate, the film contrast described above which are killed for instant seconds. This film uses MKV package.


P. 38: We mishap 720P/1080I!. .


From the above ones see, we have adopted different encodings, different packages of ones though, but no part of the 720P/1080I, which may be confused with some other friends: in fact, HDTV is downloaded and played the most are 720 p HDrip, and why they do the test. Teddy bear online www. .com .cn .beareyes... ".


Because both 720P Ye Hao, is 1080I Ye Hao, from the formula, we have been very easy to figure out they are only half the bandwidth for the 1080P, which is only half the hardware requirements. Furthermore, 720P/1080P positioning caused by the general rate is very low, the same format, the lower the bit rate the lower the hardware requirements. .


Weigh the above two factors, typically 720P/1080I hardware requirements for 1080P only 1/4 to 1/2, or even lower. This is really no need to test, if even the 720P/1080I can provide smooth playing, this PC is too old.


In addition, we in the "integration is hope! MCP68 full detailed Hengce "test in the soft solution has been tested even the most complex x264 / H.

There may be a friend asked why the beta platform is not in VISTA but still old XP system. After the author's survey, the majority of HDTV enthusiasts to come into contact with Vista now is much, much less use of VISTA system. In XP the old platform test is undoubtedly the most representative. Of course, if the subsequent increase in VISTA user, we will consider adding VISTA test platform.


To test to avoid errors, we use the system comes with perfmon, all new sources began in the first 5 seconds (babel Because of titles so that 40 seconds) when the empty records, re-start record CPU utilization, in 1 minutes and 40 seconds after data collection. After our tests have, in addition to the minimum CPU share some slight error, the largest share of CPU share and the average error of less than 1%. But when the CPU reaches 100% after, PERFMON record error sometimes quite outrageous, so in order to avoid all misunderstanding, we will record the results as 0. .


This time the tests we turned off all sound cards and peripherals, video playback CPU does not relate to this piece of audio decoding.


For the test, the more useful the data is true that the maximum CPU utilization, and average CPU utilization, rather than the minimum CPU utilization. The average occupancy rate in most cases the representative is to be fluent, but the maximum occupancy rate often determines whether or cards will be thrown about, the two values are very important. Separator regard, we all use Haali splitter to separate, and in the decoder hardware decoding on those three, plus CoreAVC, FFshadow to complement the soft decoding test. .


In addition, we only can use PowerDVD test directly instead of using PowerDVD KMP, PowerDVD cannot be detached, or when the package is the inability to use the hardware decoding KMP plus perfect decoding.


Every time we finish the test, will cut a graph, as three individual shots traditions, there is also a JPG BMP, all together, so big. . Some of these tests has not yet been shot, showing that workload. .

This test is to discuss the different ones (different coding) on the same platform, the difference what system load, and let everyone know the encoding of the difference between soft solutions.


Babel is very, very loss of resources, we can see in the Core 2 duo E6850 Fengyun the most powerful CPU, the peak in the soft solution reached 82%, while the average occupancy is also 72%. While watching films generally, few will conduct multi-task, but hung up subtitles, then open BT and other background process, making life difficult to ensure E6850 completely smooth playback, the fact that it is far the most powerful Core 2 Duo, so we arrive at a conclusion, Babel source of this film is not suitable for soft real solution. .


Although the average of the 007 Royal Casino is slightly better than predecessor's banner to lower, but the highest occupancy rate is the most deciding factor whether card, minimal consumption continues to be the Royal Casino high out of the section, so we found the Royal Casino in hardware requirements better than father's banner. The Pirates of the Caribbean and the fathers of the banner also Hollingsworth, if integrated is still Pirates of the Caribbean in H .264 is. lowest occupancy rate.


In fact, both the Royal 007, or Flags of Our Fathers, or the Pirates of the Caribbean, all represent the latest 1080p H. H.264 high rate of CPU utilization, overall the side while not Babel metamorphosis, but higher than the VC-1 come together. And we saw from the table, H. H.264 inter BABEL other three sources outside the average CPU utilization is not high on the VC-1 too, only at the highest CPU utilization will suddenly soaring, see H. H.264 the CPU utilization curve can also see this to often turn the corner. .


VC-1 changes the CPU usage is very small, only a maximum of 20% more, relative to H .264 to smooth it. ', so as long as you make basic fluency VC-1 become, also will not appear on the status of the card.


MPEG-2 is really not to mention the CPU occupancy, and now the CPU occupancy QQ almost higher than his, no wonder there is an old friend of machine will VC-1 / H. H.264 convert MPEG2 to make a. .


Summary: the CPU usage rate, Babel > 007 Royal Casino > parents > banners > diamond > Pirates of the Caribbean dream girl band of brothers, H >. > > MPEG4 .264 VC-1.

The test purpose is to allow us to know the different coding Yaoqiu minimum CPU frequency / type, or is the CPU Zhao Ge Zi Ji performance close to the pigeon-holing, 看 can not but has a great flow of the extract. .


First, let's define the concept of a smooth, and smooth, not only most of the time, but not the card. Teddy bear online www. .com .cn .beareyes... ".


This will make on the CPU occupancy rate of two requirements:. .


1: CPU occupancy rate cannot exceed 80%, over 80% after a daemon running may lose smooth feeling.


2: CPU can not exceed the maximum occupancy rate of 90%, even if you average occupancy rate of less than 50%, but 90% of cards at once may make the screen appear the status card or Dayton. So our testing is carried out based on the above conditions. MPEG2 first start since all of the above CPU through the MPEG2 test, even the weakest ATHLON 64 3000 + have entirely no problem. .


VC-1 aspects, we have the highest level of diamond to represent, we use the FX62 single core overclocked to testing of 3 g, because we cannot FX57 before through this test, the maximum CPU usage rate of 94%, sent off.


In it we see a single core to levy the highest test frequency is only through it, to less than 1% CPU utilization punched edge ball, which means that all single-core CPU overclocking will not be able too do not measure. Follow-up test PD915 can also pass the test, but also just pass. .


.264, H. We use the highest level of Babel to test. I tried Super 3. Celeron M430 .4G's are unable to resolve their problems, it seems soft non-dual core. The duo also must be today, we see in the block to E6750 E6550 but still not running smoothly, and the highest is more than 75%, 93. can only be said not to qualify.


Babel needs more CPU e6750 truly smooth operator. .


Now we all can pass the test of the CPU for you to understand all the ones you need and what kind of CPU.

Page 42: graphics core frequency on video acceleration whether watching video need to buy a high-frequency card?.


3D graphics acceleration core and the core of what the video directly related to the frequency of the video acceleration core is not moving to follow the core frequency. Is this because the core frequency of different makes video acceleration is different. Center frequency of floating video acceleration for GF8600 affected very little value very close to, can be seen as no effect. While the HD2600XT is some impact, but can be seen and not directly proportional to frequency, so it can be seen and the core independent of frequency. Bear online www. . Beareyes. . Com. . Cn. .


In other words, you can either buy a high-frequency version 8600GTS or low frequency version 8600GT, is for watching video. HD2600XT is also the same reason, from here, only the core frequency and 3D performance, and video acceleration performance is irrelevant.


Page 43: a new generation of graphics card video acceleration in the help of different sources on-chip CPU requirements. .


GF8600 for H .264 acceleration capacity. ' is quite good, but in some sense when dealing with VC-1. But on the contrary, HD2600 this is very good, the highest of all applications are not more than 50% CPU usage, but this is just a 1. .6G single core CPU.

This test is found in the testing process, when we check in the back head and discovered the problem, and I see what the problem is a piece of it. .


This is in line with the 3800 + 8500 when soft extract VC-1 diamond cut figure, because at that time didn't notice did not stop the whole map.


And we also do not change with the 2600XT hardware decoding of the case open, CPU occupancy rate was down. From an average of 53% to 39%. .


We see the disable ATI AVIVO tool is a PowerDVD, shouldn't the same CPU soft extract should be the same, this is it.


PowerDVD in the original VC-1 which can only control the Pixel Prediction (pixels forecast) and Deblocking (ring block filter solution) of the switch, and can not directly control the Frequency Transform (frequency conversion) of the switch, so the default in the driver support is open with the. As a blueprint as indicated. .


PowerDVD's switch does not fully support all of the steps.
