摘要：In an audio and video reproduction system receiving multiplexed data whichcomprises an audio packet comprising an audio packet header and audio packet data andcomprising an audio buffer memory for storing the audio packet data as stored audiodata, the audio packet has a plurality of audio rates which correspond to a plurality ofrate modes. A detecting block detects a size of the audio packet data as a detectedaudio data size. A counting block counts the detected audio data size to produce acounted audio data size. A time indication signal generating unit generates a timeindication signal by the use of reception system clocks and a time value which ispredetermined in relation to the plurality of rate modes. A latching circuit latches thecounted audio data size as a latched audio data size on reception of the time indicationsignal. A CPU decides one of the plurality of audio rates as a decided audio rate to adjustan audio reproduction time of the stored audio data in accordance with the decided audiorate.
