Abstract
A signal subjected to compression coding and multiplexing by a video/audio coding circuit is subjected to signal processing such as shuffling by a recording signal processing circuit. A control ECC block generated by a control ECC block attaching circuit is multiplexed with video/audio data to be recorded on a disk. Data played back from the disk is subjected to processing such as deshuffling by a play-back signal processing circuit. The control ECC block is played back by a control ECC block playing-back circuit. Video/audio data is decoded by a video/audio decoding circuit to be output.
