Abstract— In this paper, we focus on 2 : 1 spatial resolution downscaling transcoding from MPEG-2 to WMV. We propose two architectures (for sequences with or without B-frames res...

In network delivery of digital video, if the bandwidth required for a video is not available, the video has to be recoded at a reduced bit rate. It is highly desirable that the tr...
