Copyright protection for digital signal recording and/or reproduction and recording medium thereof |
| abstract |
A digital image signal recording and/or reproduction method and/or apparatus by which a copyright protection signal employed by a software tape for use with an analog video tape recorder can be recorded and/or reproduced with a digital video tape recorder of the compression type is disclosed. When a copyright protection signal detection circuit detects a disturbing signal inserted in a video signal, an output of an analog to digital converter is stored into a memory. An H counter supplies a line number upon detection of the disturbing signal as LINES data to a line pack processing microcomputer. The data of the memory are supplied as line data to the line pack processing microcomputer under the switching control of a switching circuit. Using the received data, the line pack processing microcomputer produces pack data and sends the pack data to a format converter of a digital video tape recorder. |
