Patent ID: 8472531

Claim:
A Motion Picture Expert Group (MPEG) error concealment system, comprising: a MPEG transport processor, wherein the MPEG transport processor is operable to receive a live streaming MPEG transport stream, the MPEG transport processor operable to identify a transport error within a MPEG transport stream layer of the live streaming MPEG transport stream; and a MPEG decoder coupled to the MPEG transport processor, the MPEG decoder concealing the transport error based upon an error concealment operation, wherein, when a discontinuity of a programmed clock reference time base occurs, the MPEG decoder disables time-base management to conceal the transport error during live decoding and to allow a plurality of pictures within the live streaming MPEG transport stream to be decoded, wherein the MPEG decoder switches back to the time-base management when the plurality of pictures based on a previous time-base is decoded and displayed; and when a mismatch between a presentation time stamp of the live streaming MPEG transport stream and a video system time clock occurs, the MPEG decoder produces a category type of the transport error contained within the live streaming MPEG transport stream by comparing a difference between the presentation time stamp of the live streaming MPEG transport stream and a video system time clock to a predetermined threshold, each category type designating the error concealment operation of a plurality of error concealment operations.
