摘要

A channel selection device used in a digital/analog broadcasting receiver changes a channel according to a channel upward/downward changing instruction by selectively using the following procedures. The first procedure B is used to search for a desired physical channel when there is no channel information; the second procedure A is used to select a channel when there is information of the current physical channel; the third procedure is used when a channel to which the current channel is changed upward/downward exceeds the current physical channel range; and the fourth procedure D is used when information of all the channels is held. Thus, it is possible to appropriately select a channel automatically and also to obtain the channel information automatically when the channel is changed.
