When a digital broadcasting channel and an analog broadcasting channel, over which the same program is currently being transmitted, are provided by a broadcasting station, upon each depression of a digital/analog switching button on an operating unit, an MPU alternately switches between the digital broadcasting channel and the analog broadcasting channel across which the program is being transmitted. And when the current broadcasting station provides a digital broadcasting channel and an analog broadcasting channel across which the same program is currently being transmitted, the MPU alternately switches between a predetermined digital broadcasting channel and a predetermined analog broadcasting channel.
