A digital video signal processing system includes apparatus for concealing errors which might occur in reproduced images due to image data lost during signal transmission. The system includes circuitry for detecting transmitted video data (20-24), gen- erating error signals if errors are present in segments (transport blocks) of the received data (25), and excising segments having errors from the data stream. The received data is applied to a decoder/decompressor system (26, 27) which decodes and decom- presses the transmitted video data according to a predetermined sequence. The decompressed video data may be applied to a memory (318) for subsequent display, recording, etc. The decompressor is responsive to the error signals for altering the predeter- mined sequence.
