Paper Abstract
Considering a video signal which has ben degraded by a PAL codec and a noisy transmission on a satellite channel, tow digital filtering schemes are presented for reducing the different resulting signal distortions before its MPEG2 encoding. The first one deals with crossing-effect and transmission noise using a single non-linear filtering box, while the second scheme consists of several linear processing, each one devoted to one kind of distortion. Both filtering approaches are discussed, and their performances before and after the MPEG2 codec are compared, using objective, peak signal-to-noise ration, as well as subjective, visual quality, criteria.
