Abstract
A ground wave video signal is extracted by a ground wave video decoder from a ground wave broadcast signal received by a ground wave 2 tuner. A BS program link information signal is extracted by a BS program link information decoder from a BS broadcast signal received by a BS2 tuner. An AM radio sound signal is extracted by a radio sound decoder from an AM radio broadcast signal received by an AM radio tuner. The extracted ground wave video signal and BS program link information signal are displayed as videos by a display device, while the extracted AM radio sound signal is output as a sound from a speaker.
