Abstract
It is an object of the present invention to provide a television receiver for discriminating a CM broadcast from a received television broadcast and controlling a volume of the CM broadcast without complicating a configuration of a discriminating process of the CM broadcast. The present invention includes a silence detection means, a scene change detection means, a video audio changing point detection means, a first characteristic amount extraction means, a second characteristic amount extraction means, a comparison determining means and a volume control means. The comparison determining means compares the first characteristic amount which is an audio characteristic amount of a television signal before the time when the video audio changing point is detected, and the second characteristic amount which is an audio characteristic amount of a television signal after the time when the video audio changing point is detected, to determine whether a predetermined condition is satisfied or not. The volume control means controls an output level when outputting audio of the television signal on the basis of a result of the comparison determining means.
