ABSTRACT:
A content, restored in an information processing apparatus, for replaying a content, such as a personal computer, is fed back to a drive device. The drive device detects an electronic watermark from the transferred restored content, and controls content outputting from the drive device. In this arrangement, an electronic watermark is reliably detected and content replay control is performed based on the detected electronic watermark in any type of coding including MPEG 2, MPEG-1, MPEG-4 regardless of type of coding or even if the content is encrypted.
