Abstract
Error correcting section holds PTS(n−1) and DTS(n−1) of the frame immediately preceding the current frame and the most recent CPTS as determined to be correct in the past. The time stamp of the current frame is determined to be incorrect if (1) CPTS>PTS(n) which is the current frame or (2) CPTS<PTS(n) and greater than the time interval of time information B_TS(n)−B_TS(n−1) plus a reference time (e.g., the multiple of the standard frame interval 33 msec of moving images using 30 frames per second). If the PTS(n) of the current frame is correct, it is used as reproduction timing and updates the CPTS, using the PTS(n). If, on the other hand, the PTS(n) of the current frame is incorrect, it is not used and the time obtained by adding the CPTS and B_TS(n)−B_TS(n−1) is used as corrected PTS(n).
