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 complexity and the quality. We achieve resolution...
In this paper, we study the problem of video transcoding from MPEG-2 to WMV format, together with several desired functionalities such as bit rate reduction etc. We propose two architectures (for different typical application scenarios) that are unique in their complexity scalability and adaptive drifting error control, which in return provide a mechanism to achieve desired trade-off between the complexity...
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 unique in their complexity scalability and...
