Abstract
Error concealment for motion picture expert group (MPEG) decoding with personal video recording functionality. The present invention is operable to perform error concealment of MPEG data within various components within playback, recording, reading and writing data systems. The present invention is operable within existing systems whose components may not be capable of accommodating errors within MPEG data. Whereas prior art systems typically cannot deal with any corruption without either losing the data or suffering some operational failure, the present invention is able to conceal these errors and to continue decoding and presentation of the MPEG data. In certain embodiments, this involves maximizing the available data that contain no errors to conceal those portions of the data that do include errors. The present invention is operable to accommodate various layers while performing error concealment, including the MPEG transport stream layer, the video layer, and the audio layer.
