In the transmission of a preceded, stored video such as that in video-on-demand systems , it is often necessary to reduce the bit rate of the compressed video in cases that the network capacity is reduced. This paper proposes a novel block-dropping approach for rate shaping of MPEG-precompressed video. A directional spatial interpolation scheme is incorporated at the receiver to reconstruct faithfully a large percentage of the blocks that are intelligently dropped to meet the constraint of… CONTINUE READING
