摘要

在本文中，我们评估了两种MPEG-1视频滤波机制，即低通滤波和选择性丢帧。该评估提供了带宽需求减少和交付给客户端的视频序列感知质量之间的权衡。大量的实验表明，这些过滤机制在保持可接受的感知质量的同时显著降低了带宽需求。

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.
