Abstract
A synchronous decoding method for AV packets that solves the problem of asynchronous AV signals resulting from the decoding restoration of an AV packet-type bitstream. No large PTS memory is needed as an index table for a video buffer with the method. One PTS value is sampled and recorded at one time. The old PTS value is replaced in the next sampling. The rest of the unrecorded PTS data are estimated using the frame rate and the previous PTS value. This method not only simplifies the structure but also provides a smoother playing effect for an AV source with a higher error rate, rendering better noise tolerance.
