    摘要： A signal transmission method applicable to prevention of modification or alteration of the playback mode information, such as copying management information or charging information. The playback mode information form a terminal 15P is data-converted for ciphering by a playback mode information appendage circuit 14 in a header appendage circuit 13 responsive to the key information from a terminal 15K and the resulting information comprised of the data and the playback mode information is outputted. The reproducing side effects data conversion on the ciphered playback mode information for deciphering, by a playback mode information detection circuit 26 in a header separation circuit 25, using the key information from a terminal 27K, for taking out the original playback mode information at a terminal 27P.

    摘要： A signal reproducing apparatus for prohibiting copying or unauthorized use. The apparatus includes a copying management information decision circuit 19 for discriminating the state of the copying management information read out from each header of a data sector and within the TOC, a protect signal generating circuit 20 for generating a protect signal based on the discrimination signal and a mixing circuit 24 for mixing a protect signal in a vertical blanking period of an analog video signal D/A converted from digital video data reproduced from an optical disc D. The apparatus also includes a descrambling circuit 31 for descrambling the digital data based on the copying management information and a scrambling circuit 32 for descrambling the digital data. The apparatus enables prohibition of unauthorized analog copying and digital copying, inhibition of serial generational copying and prohibition of unauthorized analog and digital copying simultaneously.
