Reduced Frame Quantization in Video Coding
We vary the quantization parameter in H.264 video encoding by increasing it by a well-chosen offset in every other frame, which we call reduced frames. As the motion compensation ...

On the Design of Prefetching Strategies in a Peer-Driven Video on-Demand System
In this paper, we examine the prefetching strategies in a peerdriven video on-demand system. In our design, each video is encoded into multiple low bit-rate substreams and copies ...

A generic and automatic content-based approach for improved H.264/MPEG4-AVC video coding
A new content-based approach for improved H.264/MPEG4-AVC video coding is presented. The framework is generic because it is based on a closed-loop texture analysis by synthesis alg...
