A video recording and playback apparatus which can perform the recording operation and the playback operation without a synchronous conversion circuit is provided, even if recording and playback are asynchronous. An SDI signal containing video content is coded by input processing unit 141, and the coded video data is temporarily held by input buffer 142. The coded video data is read from input buffer 142, is outputted and is stored in storage processing unit 15. Other coded video data stored in storage processing unit 15 is read and is held temporarily in output buffer 161. Reading-out of the coded video data from input buffer 142 does not synchronize with an input synchronizing signal and is performed according to the cycle of the synchronizing signal generated by external synchronizing signal detector unit 12, and the coded video data read out is transmitted to storage processing unit 15.
