Abstract
A digital broadcasting receiver includes an operating section configured to select a channel, and a video/audio data obtaining section configured to obtain video/audio data on a selected channel from television broadcasting signals. The digital broadcasting receiver also includes a channel table and a designated channel table. The digital broadcasting receiver further includes a channel selecting section configured such that when the channel is selected by the operating section, the channel selecting section determines whether or not the selected channel has been replaced with an alternative channel by a broadcasting station by reference to the two tables. If it is determined that the selected channel has been replaced with the alternative channel, the channel selecting section instructs the video/audio data obtaining section to select the alternative channel instead of the selected channel.
