An audio/video decoding system capable of providing sufficient synchronization between an audio output and a video output. The decoding system has a parser, an audio decoder and a video decoder. The parser extracts an SCR (System Clock Reference), an audio time stamp and a video time stamp from a system stream, and demultiplexing the system stream into an audio stream and a video stream. The audio decoder computes an output timing for an audio output based on its decoding time, the SCR and the audio time stamp, and decodes the audio stream in accordance with the output timing. The video decoder computes an output timing for a video output based on its decoding time, the SCR and the video time stamp, and decodes the video stream in accordance with the output timing.
