Abstract
In this paper we consider the problem of temporal channel error propagation, within a motion compensated video codec. To combat this problem we propose a new coding strategy, based on the coding of absolute values, rather than differential values. The proposed technique is flexible enough to be useful with a wide variety of coding methods, including DCT, wavelet coding and matching pursuits. Results are presented which demonstrate that the proposed technique allows much quicker recovery from errors than other existing techniques such as periodic replenishment. The method has the additional advantage, that the important active regions of the image are recovered more quickly than stationary background areas.
