Abstract:
1. An audio-video recording device that records a video signal and an audio signal of television broadcast into a recording medium, comprising: a transition-point detecting unit that detects, from the video signal or the audio signal of the television broadcast, its transition points; a CM-broadcast-period detecting unit that detects transition points that occur corresponding, with a predetermined tolerance, to a time interval specific to a CM broadcast, to thereby recognize a period defined by the thus detected transition points as a CM-broadcast period; a CM-broadcast-period-continuity determining unit that determines whether or not the CM-broadcast period detected by the CM-broadcast detecting unit is continuous with one previously detected; a CM-broadcast-period-information-recording controlling unit that includes a record allowability flag indicating whether or not recording to the recording medium is allowable, that controls to record into the recording medium at a predetermined timing, when the flag indicates a record-allowable state, time information representing CM-broadcast periods determined, among those detected by the CM-broadcast-period detecting unit, to be continuous by the CM-broadcast-period-continuity determining unit and that makes the flag indicate a unallowable state for a predetermined time after recording to the recording medium; a CM-broadcast-period-information selecting and unifying unit that selects plural information of the CM-broadcast-periods from among those stored in the CM-broadcast-period-information-recording controlling unit, and unifies the plural information to provide information of another CM-broadcast-period to be recorded; and an information recording unit that records into the recording medium, the time information representing the another CM-broadcast period outputted from the CM-broadcast-period-information-recording controlling unit.
