摘要

When a format of a video signal or an audio signal received by a receiver of a video/audio signal input/output device is switched by a channel selecting operation by a user, a format determiner determines an output format. An output format communicator transmits format information indicating the output format to a video/audio reproduction device through a communicator. After a converter switches the output format, the communicator transmits the video signal and the audio signal to the video/audio reproduction device. When a communicator of the video/audio reproduction device receives the format information, a format switcher switches reproduction setting of a display based on the format information. After that, when the communicator receives the video signal and the audio signal, the display reproduces video and audio.
