Seamless integration of video coding into all current protocols In terms of the complete Home Media Ecosystem, new emerging content delivery and distribution models enable the transfer of video content among devices on the home network. As mentioned earlier, the Digital Living Network Alliance is developing guidelines to ensure seamless interoperability in the home. A codec is only one of many necessary pieces. VC-1 (WMV-9) facilitates interoperability, being part of a platform that includes: Flexible Digital Rights Management adopted by all major Studios and Music Labels (e.g., MovieLink, CinemaNow, …) Flexible, scalable Server Popular Windows Media Player and MovieMaker 1000’s of 3 rd -party SW/HW solutions supporting this platform, including chips, STBs, CE devices, etc.
Now I would like to focus a bit on the details of the codec itself. As you can see from this slide, VC-1 shares some of the same features as H.264. In fact, this overlap in feature sets is a major reason why many companies are currently integrating both codecs into the same chip. You’ll also notice, though, that there are many differences in features. One reason is how the codecs were designed. The coding techniques used in H.264 were originally designed for low-resolution (e.g., CIF), low-rate video with HD support added later. 4x4 Transform, “strong” loop-filter, 6-tap motion compensation, etc. result is softer video with less detail On the other hand, the coding techniques in VC-1 were designed considering both low-resolution, low-rate video and HD, high rate video. 4x4, 4x8, 8x4, 8x8 Adaptive Block Transforms (ABT), “texture-adaptive” loop-filter, 4-tap motion compensation, etc. result is sharper video with more detail One example of where the techniques make a difference is the Adaptive block transform. Independent research studies have demonstrated that the Adaptive block transform used in VC-1 gives Better reproduction of textures and film grain Fewer ringing artifacts at edges when using 4x4 blocks Key factor in improved perceptual quality, especially for HD video (Gordon, JVT-H029, May 03; Wien, IEEE CSVT, July 03) Training set has a big impact on the end result
Plot and tabulate. Codec complexity is another important issue critical factor. In the hardware space, lower complexity means less silicon, lower cost and fewer heat issues. Complexity was taken into account during the design process for VC-1, with careful consideration given to various alternative designs. As a result, VC-1 decoding is more than 2x faster than H.264 decoding. And full 1080p decoding is possible on today’s off the shelf PCs. Biggest difference is seen with DSP implementations. Companies can do more on a single DSP with VC-1 because it’s easier to implement. For example, Equator has been able to support both SD and HD (up to 720p) on a single DSP. Equator BP-15 : VC-1 SD and HD (up to 720p) In all of these studies, many different codecs were tested including MPEG-2 various implementations of MPEG-4 various implementations of H.264 and Real video DV magazine - ProCoder MPEG-2, Sorenson MPEG-4, Real9, VC-1 (WMV-9) C’T Magazine - Dicas MPEG-4, DivX 5.0.4, VSS H.264/AVC, On2 VP3.1, QT 6.1, Real9, Sorenson 3.1 Pro, Sorenson MPEG-4, VC-1 (WMV-9), XVid MPEG-4 DVD Forum - 9 codecs total, including several RD optimized implementations of MPEG-2, MPEG-4 and H.264/AVC EBU - Real 9, VC-1 (WMV-9), Envivio MPEG-4, Apple MPEG-4
