Abstract

Elements of the compressed video signal which are of greatest importance to signal decompression are set a plurality of times in redundant transport cells. Media error codes are concatenated to the redundant data such that when and if such redundant data is applied to the corresponding decompressor, the media error code will automatically force the decompressor to resynchronize.
