In this paper, we study the problem of video transcoding from MPEG-2 to Windows Media Video (WMV) format, together with several desired functionalities such as bit-rate reduction and spatial resolution downscaling. Based on in-depth analysis of error propagation behavior, we propose two architectures (for different typical application scenarios) that are(More)
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 respectively) that are unique in their complexity scalability and efficient control over the drifting error, which in return provide a flexible mechanism to achieve desired tradeoff between the(More)
