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