Abstract: A television receiver system is configured to include a television receiver apparatus (100) and a remote control apparatus (200). The television receiver apparatus (100) outputs one of video and audio signals on a received broadcast wave and video and audio signals inputted from an external electronic equipment (300), and transmits the video and audio signals by radio. The remote control apparatus (200) controls an operation of the television receiver apparatus (100), and receives and outputs the video and audio signals transmitted by radio. A power saving control apparatus for the television receiver system controls turning off power supply to at least one part of m units of the television receiver apparatus (100) upon receiving a predetermined instruction signal from the remote control apparatus (200).
