摘要：A video recording/reproducing apparatus capable of discriminating commercialmessage portions even when a broadcasting mode is the same. A magnetic head recordstelevision broadcasting signals to a magnetic tape and reproduces the television
broadcasting signals from this magnetic tape. When the television broadcasting signalsare reduced by recording/reproducing apparatus, an audio-free portion detector detectsaudio-free portions from audio signals in the television broadcasting signals. Commercialmessage (CM) portion detector detects the commercial message portions in thetelevision broadcasting signals by the time intervals among a plurality of audio-freeportions detected by the audio-free portion detector, and a CM information memorycircuit stores the information of the recording positions of the commercial messageportions detected by this commercial message portion detector to the magnetic tape.When the television broadcasting signals are reproduced from the magnetic tape,reproduction is carried out while the commercial message portions are skipped, at therecording positions of the commercial message portions to the magnetic tape, on thebasis of the information of the recording positions of the commercial message portionsto the magnetic tape that are stored in the memory circuit.
