When a priority channel is set, a user tunes in on a channel to be the priority channel in a receiver. Priority channel registration processing is started in data broadcasting appended to the channel. The receiver acquires a telephone number of a broadcasting enterpriser device in data broadcasting, and connects a telephone thereto. The broadcasting enterpriser device acquires user information from the receiver, and stores in the receiver its broadcasting enterpriser code as the priority channel. Thereafter, the channel having the broadcasting enterpriser code is tuned in on when a TV is turned on.
