Digital video and audio signal playback and illegal dubbing prevention device |
| abstract |
(Objective) The object of the present invention is to reliably protect the copyright of data when dubbing using the analog output terminal of a digital VCR, and also to know information such as copy generation of the data.n n n (Configuration) The system data reproduced by the digital VCR 1 is supplied to the system data processing circuit 6. The system data processing circuit 6 supplies a control signal to the CP signal generator 10 or the VBID generator 11 based on the supplied data. CP signals or VBIDs are supplied to the recording-side digital VCR 20 and the analog VCR 40. The VBID detector 22 of the digital VCR 20 detects the VBID. In the analog VCR 40, when there is a CP signal in the analog video output, the AGC circuit 41 is disturbed. |
