发明名称 Audio and video reproduction system comprising audio reproduction time adjusting unit
摘要 In an audio and video reproduction system receiving multiplexed data which comprises an audio packet comprising an audio packet header and audio packet data and comprising an audio buffer memory for storing the audio packet data as stored audio data, the audio packet has a plurality of audio rates which correspond to a plurality of rate modes. A detecting block detects a size of the audio packet data as a detected audio data size. A counting block counts the detected audio data size to produce a counted audio data size. A time indication signal generating unit generates a time indication signal by the use of reception system clocks and a time value which is predetermined in relation to the plurality of rate modes. A latching circuit latches the counted audio data size as a latched audio data size on reception of the time indication signal. A CPU decides one of the plurality of audio rates as a decided audio rate to adjust an audio reproduction time of the stored audio data in accordance with the decided audio rate.
