Abstract: Disclosed is a channel setting processing including the steps of: generating a channel map data including physical channel information about a physical channel available to receive a broadcast signal, the physical channel information being at least a main channel number of a virtual channel, a sub channel number of the virtual channel, a broadcast station name, and a predetermined program information indicating program contents; judging whether or not there exist plural physical channels on standby for reception and capable of sharing the same program there between, based on at least two kinds of information among the physical channel information, recorded on a channel to channel basis on the channel map data; and, based on the judgment that there exit plural physical channels sharing the same program, disenabling other physical channels except one physical channel thereamong to be selected despite the instruction of physical channel selection through external manipulation.

Abstract: The present invention discloses an inputs switching device, includes: a plurality of external inputs accepting unit to accept different external inputs; a switching order storage unit to store a switching order of the external inputs to be output; an external inputs switching unit to switch the external inputs to be output sequentially as set forth within the stored switching order in response to a pressing of an operation key; and a non-switching unit to make the external inputs switching unit not to switch a specified external input that is specified from the external inputs of the switching order.
