Abstract. We introduce the concept of Dynamic Rate Shaping, a technique to adapt the rate ofcompressed video bitstreams MPEG-1, MPEG2, H.261, as well as JPEG to dynamically varyi...
This paper addresses the problem of bit allocation among frames in a predictively encoded video sequence. Finding optimal solutions to this problem potentially requires making an ...

A steepest descent based bit allocation method with polynomial iteration complexity for minimizing the sum of frame distortions under a total bit rate constraint is presented for ...
Compressed video bitstreams require protection from channel errors in a wireless channel. The threedimensional (3-D) SPIHT coder has proved its efficiency and its real-time capabi...
In this work we compare non-scalable video coding with data partitioning using H.264/AVC under similar application and channel constraints for conversational applications over mob...
