Systems and methods of error resilience in a video decoder
WO 2002071736 A3
Abstract
The method and apparatus conceal errors in images of a corrupted video bitstream (2); that cover usable video data from partially corrupted data; that advantageously reconstruct and decode video data (3), such as video object planes (VOPs), using forward error correction (FEC) codes embedded in the video bitstream; and that manage data received in a video bitstream. Various concealment techniques are performed in this apparatus. Embodiments inspect corrupted data packets identify the location or locations of an error, whether the corrupted data packet contains data expected to be error-free (6), data should be used. Backward compatible techniques of decoding FEC codes embedded in video bitstreams are shown (9).
