Abstract

During recording of a TV signal on a VCR, data is accumulated representing time of occurrence and duration of events in the television signal, and is stored in memory (42). A time code generator (50) generates time codes which are written on the tape as it is recorded. After recording, the stored data is analyzed to classify the content of the TV signal and a playback map is constructed and stored in memory (64). During playback, the map is retrieved and stored timing data are compared with timing reference data read from the tape. The VCR is fast forwarded when the tape reaches the beginning of a portion of the video signal that has been classified for elimination during playback. The VCR is put in the "play" mode when the tape reaches the end of that portion of the video signal. Since the entire TV signal is recorded, all of the signal may be viewed, even if parts have been misclassified.
