ABSTRACT:
During recording of a television signal on a VCR, data are accumulated with respect to the time of occurrence and duration of detectable events, such as blank frames, in the television signal, and such data are stored. Subsequent to the recording process, the stored data are analyzed to classify the content of the television signal between the detectable events as commercial or non-commercial. The video tape is then marked at the beginning and ending of each commercial group. During playback, the VCR is automatically commanded into a fast scan mode when the tape reaches the beginning of a commercial group. The VCR is then automatically commanded to return to the normal "play" mode when the tape reaches the ending time of that commercial group. Since all of the television signal is recorded on the tape, any or all of the signal may be viewed at the discretion of the viewer.
