摘要 |
A signal recording/reproducing method and apparatus, signal record medium and signal transmission/reception method and apparatus, whereby a signal recorded on a signal record medium can be identified as being an original signal or a copied signal. A CPU 11 generates, at a pe-set time interval, an identification signal having a meaning at a pre-set time interval, and an identification signal addition circuit 3 adds the identification signal to the video signals and/or the audio signals. A sector forming circuit 5 and circuit components up to a recording/reproducing head 14 record the video signals and/or the audio signals and the ancillary identification signal on an optical disc 12.
