ABSTRACT:
The video and audio synchronization controller sets a system clock reference (SCR) included in the frame header portion of the coded video and audio data into a system time counter to set a timing of a system time clock (STC), immediately after a video and audio reproducing device has been powered on. The video and audio reproducing device decodes and displays a first arriving video data synchronous with a display system frame pulse, which is the closest to the value of a video time stamp included in a frame header of the first video frame on the time axis of the set STC. The video and audio synchronization controller sets again the value of the time stamp included in the first video frame to the system time counter to update the STC. The video and audio reproducing device outputs the video data for the second and subsequent video frames and all the audio data synchronous with the updated STC by outputting the video and audio data when the time indicated by the video and audio time stamps arrives on the time axis of the updated STC.
