摘要： A separation unit accepts a digital video and audio signal sent from outside in units of packets and separates the signal into video data and audio data. The audio data separated by this separation unit is written for each packet in an audio data buffer, from which the written audio data is consecutively read out. Moreover, a available capacity determination unit determines a available capacity in the audio data buffer. Based on a result of the determination by this available capacity determination unit, an oscillation frequency of a frequency variable oscillator and the reading at said audio data buffer are controlled.
