Abstract
A recording apparatus includes a disc recording unit for recording each video section composing a broadcast program onto a rewritable optical disc; an electronic watermark reading unit for reading electronic watermarks embedded into the video section; and a recording flag storing unit for storing a recording flag. If the read electronic watermarks show that recording is permitted, the recording flag is set as “0” to record the next video section. If the read electronic watermarks show that recording is prohibited, the recording flag is set as “1” not to record the next video section. If a broadcast program is newly selected under a condition where the recording of the currently received broadcast program is prohibited, the recording flag is reset to “0” and the first received video section of the newly selected broadcast program is recorded onto the rewritable optical disc.
