Conventionally, a particular countermeasure has been taken for each of the error factors. That is, each error requires a circuit and the like for carrying out the countermeasure, which leads to an increase size of the entire circuit.The present invention includes a controller 14 which resets a system time clock STC serving as the system reference time with a time management information PTM in a video decoder 7. This reset time is compared to a time management information PTM or DTM of the video decoder 7 or an audio decoder 11. According to a result of the comparison, the synchronization lag between the video signal and the audio signal is controlled.
