摘要： A method of processing a sequence of coded video frames conveyed by a digital data stream, where each frame represents an image, includes receiving the sequence of coded video frames at a recording device, determining a frame interval between presentation of an ith coded frame of the sequence and an (i+1)th coded frame of the sequence, calculating a stream time stamp for the ith coded frame, and calculating a stream time stamp for the (i+1)th coded video frame based on the stream time stamp for the ith coded video frame and the previously determined frame interval.

摘要： Systems and methods for a self-correcting DVR record pipeline may provider for simpler, lower cost transport producer hardware elements. A free running transport pipeline producer may fill transport buffers without waiting for feedback from the data consumer that data has been completely processed. The pipeline data consumer independently detects transport buffers that are overwritten before processing on the buffer content is complete. The pipeline data consumer drops or deletes any invalid content or stream data to recover from the data overflow condition.
