Abstract:
1. A broadcast receiver comprising: a memory; a receiving unit to receive a plurality of broadcast signals that includes broadcast guide information relating to a predetermined broadcast program through an antenna; an external device connecting section that includes a plurality of connecting units, to which a plurality of external devices that output a video signal relating to a predetermined video content, are connected; a program outputting unit that supplies a broadcast program that corresponds to one of the plurality of broadcast signals received by the receiving unit, or the video content that corresponds to the video signal outputted by the external devices connected to the external device connecting section; an external input selection section to select a first connecting unit, to which a first external device that outputs a first video signal relating to a first video content supplied at the program outputting unit is connected, among the plurality of the connecting units; a non-broadcasting time zone detecting section to detect a non-broadcasting time zone in which the broadcast program is not broadcasted in any of the channels because there are no broadcast signals for the receiving unit to receive, according to the broadcast guide information included in the plurality of broadcast signals received by the receiving unit at a predetermined set time; a switching time zone setting section to set a switching time zone to switch so as to enable supplying the video content that corresponds to the video signal outputted by the external devices at the program outputting unit; a timing determination section to determine whether a timing in which power of the broadcast receiver was turned on falls within the non-broadcasting time zone detected by the non-broadcasting time zone detecting section or the switching time zone set by the switching time zone setting section; and an input signal switching section to switch so as to enable supplying the video content that corresponds to the video signal outputted by the external devices at the program outputting unit, in response to a determination that the timing in which power of the broadcast receiver was turned on falls within the non-broadcasting time zone or the switching time zone, by the timing determination section, wherein the non-broadcasting time zone detecting section stores data related to the detected non-broadcasting time zone in the memory, and wherein the timing determination section uses the data stored in the memory related to the detected non-broadcasting time zone to determine whether the timing in which power of the broadcast receiver was turned on falls within the detected non-broadcasting time zone.
