Definition:VC-1 is a video codec developed for broadcast interlaced video as well as progressive video by Microsoft.
VC-1 is derived from Microsoft’s proprietary WMV-9 but awaits SMPTE ratification. VC-1 is pure video compression technology, and is expected to be deployed as key engines in satellite TV, IP set-tops and high-definition DVD recorders.
Simple and Main Profiles for VC-1 Video
The Simple and Main Profiles (SP/MP) of VC-1 are supposed to be the same as those of WMV-9 in progressive compression, respectively. However, there is no Advanced Profile (AP) in WMV-9 to compare with VC-1 AP. VC-1 AP mainly focuses on interlaced video compression technology. And, the interlace tools cannot be compared directly in both standards. Even the starting point is different — the input format is YUV4:1:1 for WMV-9, but is YUV4:2:0 for VC-1. Note that only Field-based prediction and Frame-based prediction are selectively applied in each MB in the interlace tool of WMV-9. This tool is applied...
