ABSTRACT:
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 CPU11generates, at a pre-set time interval, an identification signal having a meaning at a pre-set time interval, and an identification signal addition circuit3adds the identification signal to the video signals and/or the audio signals. A sector forming circuit5and circuit components up to a recording/reproducing head14record the video signals and/or the audio signals and the ancillary identification signal on an optical disc12.
