Abstract
When a digital broadcast is currently extracted and a switching direction instruction is accepted, determination is made as to which of a CH number (analog number) next to a currently extracted channel in the switching direction according to the order indicated in an analog CH map and a CH number (digital number) next to the currently extracted channel in the switching direction according to the order indicated in a digital channel map is closer to the number of the currently extracted channel (extracted number). When closer to the analog number, the channel is switched to the analog number. When closer to the digital number, the channel is switched to the digital number. Thus, the channel of analog and digital broadcasts can be switched in a seamless manner.
