Definition
Windows Media Video 9 (WMV-9) is a video codec developed by Microsoft, which is widely used for streaming media over Internet due to the popularity of MS Windows operating systems.
Since WMV-9 is a generic coder, many algorithms/tools of it can be used for a variety of applications under different operating conditions. Originally, three profiles were defined – Simple Profile, Main Profile, and Complex Profile. However, Complex Profile was dropped unofficially. Consequently, WMV-9 more focuses on compression technology for progressive video up to Main Profile, while VC-1, a derivative of WMV-9, is developed for broadcast interlaced video as well as progressive video. Those two technologies are almost identical in important tools except the interlace tool, and VC-1 is currently under standardization by the Society of Motion Picture and Television Engineer (SMPTE).
Key Compression Tools for WMV-9 Video
Like all other MPEG standards, WMV-9 is based on motion compensated...
