A digital broadcast receiver offering lower costs, capable of shortening the delay time required for the video display while receiving the digital broadcast, and further causing the viewer no abnormal viewing sensations. The digital broadcast receiver demultiplexes the video and audio elementary stream and time information from the transport stream, then monitors the buffer capacity during buffering of the video and audio elementary streams, and retains the statistical information. The digital broadcast receiver then checks the statistical information, and sets the play delay time for the decoded video frames and decoded audio frames from the beginning of the elementary stream. After starting the display, operation is in slow-motion-play-with-audio until the display time for a particular frame returns to the original value and the stream buffer capacity is restored. The digital broadcast receiver might instead analyze the video frame and the audio frame, and repeatedly play frames in scenes with no video movement and also scenes with no sound. |
