Power conversion device

Even when a communication state between a tuner device and a display device is deteriorated, a television broadcast receiving device enables a user to view broadcast. The television broadcast receiving device of the present invention has a tuner section that receives a digital broadcast signal, selects the digital broadcast signal to decode the digital broadcast signal, generates video data including a video signal and an audio signal, and converts the video data into processed video data suitable for wireless communication, and a display section that receives the processed video data from the tuner section through wireless communication, and displays a video based on the processed video data. The tuner section has a recording/playback section that records and reads the video data in and from a predetermined recording section according to a change in state of the communication with the display section.

Television broadcast receiving device
