ABSTRACT:
A video recording/reproducing apparatus capable of discriminating commercial message portions even when a broadcasting mode is the same. A magnetic head records television broadcasting signals to a magnetic tape and reproduces the television broadcasting signals from this magnetic tape. When the television broadcasting signals are reduced by recording/reproducing apparatus, an audio-free portion detector detects audio-free portions from audio signals in the television broadcasting signals. Commercial message (CM) portion detector detects the commercial message portions in the television broadcasting signals by the time intervals among a plurality of audio-free portions detected by the audio-free portion detector, and a CM information memory circuit stores the information of the recording positions of the commercial message portions 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 the recording positions of the commercial message portions to the magnetic tape, on the basis of the information of the recording positions of the commercial message portions to the magnetic tape that are stored in the memory circuit.
