Abstract
A data processing apparatus constituting a low-cost audio/video data transmission and reception system is disclosed. A reception buffer monitoring circuitmonitors the size of receiver data being accumulated in a reception buffer. When the size of accumulated data is found to become higher than a high threshold, the circuitcauses a reception clock generation circuitto generate a reception clock with a higher frequency. When the accumulated data size becomes lower than a low threshold, the reception clock is generated with a lower frequency. Based on the reception clock fed from the reception clock generation circuit, an audio/video decoderdecodes the audio/video data coming from the reception buffer. This invention applies advantageously to a television transmission and reception system for transmitting and receiving TV broadcast signals.
