Abstract

We study error control for an MPEG2 digital video compression scheme. The compressed video is transmitted over an asynchronous transfer mode (ATM) network. We propose to combine error control coding with error concealment. Specifically we use classical error detection to locate errors in the compressed domain, translate this information to the uncompressed domain and then use standard error concealment in the error locations. The solving of the error location problem in this way is the main contribution of this work
