Evaluation of Filtering Mechanisms for MPEG Video Communications
In this paper, we evaluate two video filtering mechanisms for MPEG-1 video, namely, low pass filtering and selective frame dropping. The evaluation provides tradeoffs between the reduction achieved in bandwidth requirements and the perceptual quality of the video sequences delivered to the client. Extensive experiments revealed that these filtering mechanisms result in a significant reduction in bandwidth requirements, while maintaining acceptable perceptual quality.
