At a reserved recording time, if a television receiver is turned off, then the television receiver is turned on, and a video of a reservation setting target channel is forcibly displayed. A content of a reserved program can be thereby checked. At this time, a mute control signal is output to a voice processing circuit to mute a voice. If a user does not transmit a volume change instruction for a predetermined time, then a TV circuit is turned off, and a reservation recording is continued. This can suppress unnecessary power consumption during user's absence.
