Abstract
The invention provides a broadcast signal recording and playback apparatus and method which can detect a CM included in a television broadcast signal with certainty without an error. A CM candidate period detection section detects a CM using an audio mode signal outputted from a tuner, a sound absence discrimination output from a sound absence detection section and a scene change detection output from a scene change detection section as basic materials. A detection operation discrimination section limits operation of the CM candidate period detection section when it is known that the broadcast signal includes no CM or when the electric field is weak.
