Abstract

Video will be an important application for communication networks. During transmission errors may occur. For compressed video, that means degradation of the picture quality. Different error control strategies have been proposed to compensate for the problem of transmission errors. In this work we concentrate on combining Error Detection together with Error Concealment. Two schemes based on that strategy were tested. The first uses redundancies which are still present in the compressed video signal. The second one relies on the redundancies that the syntax of compressed bitstream provides. The performance of those two schemes were compared against a general error correcting scheme.
