Reproduction of recorded signals.

摘要

A signal format and a reproducing apparatus compatible with that format protect copyright in recorded video and audio data against digital and analog dubbing. The reproducing apparatus senses (6) copyright information included in a signal reproduced from a recording medium to generate (10) a copyright protection signal which is placed in a vertical blanking interval of an analog output of the reproducing apparatus. If a Serial Copy Management System (SCMS) signal is reproduced, it is supplied to a digital VCR (20). The copyright protection signal disrupts the AGC of a recording analog VCR and the SCMS signal prevents a digital VCR from digitally dubbing the reproduced video and audio data.
