Abstract
A video signal decoding arrangement conceals visible artifacts attributable to errors in a data stream. The arrangement includes a data processing arrangement that decodes the data stream into image data and that replaces data corrupted by the errors with replacement data generated as a function of a previous frame. The image data is optionally stored in first and second memories.
