ABSTRACT:
A copy-protected-state indicating MPEG-TS data output unit (3) holds a bit stream obtained by previously compressing and encoding image and/or audio data representing that recording desired by the user has ended in failure because the contents is copy-protected. When copy control information (V2) outputted from an IEEE 1394 interface (1) indicates a copy-protected state, a selecting unit (20) selects copy-protected-state indicating MPEG-TS data (V3) outputted from the copy-protected-state indicating MPEG-TS data output unit (3) and outputs it as to-be-recorded MPEG-TS data (V4). Thereby, the data (V3) is recorded.
