Abstract

This paper presents an efficient error concealment implementation for damaged MPEG-4 video bitstreams. The chosen spatial and temporal concealment algorithms are designed to fit in real-time decoders and are advantageously combined in a hybrid spatial/temporal approach to provide visually more plausible pictures than basic concealment techniques. In addition, the encoder impact on the visual quality of the reconstruction in presence of channel errors is highlighted
