Abstract:
1. A digital broadcasting receiving comprising: a transport unit for separating/dividing a digital broadcasting signal that has been subjected to demodulation in order to output the separated/divided digital broadcasting signal toward a decoder; a memory unit for storing a relationship of each of a plurality of subchannels of multichannel broadcasting to each of a plurality of packet IDs in a table wherein said subchannels are defined on a standard definition broadcasting basis; a broadcast detecting unit for detecting one of one-channel broadcasting and said multi-channel broadcasting according to a packet ID which is included in the digital broadcasting signal and has been inputted to the broadcast detecting unit from said transport unit; a subchannel control unit for controlling said transport unit so that when a result detected by said broadcast detecting unit indicates the multi-channel broadcasting, a predetermined packet ID of a set subchannel is read out of the table; and a broadcasting signal including a predetermined packet ID is outputted; and a setting unit for setting said set subchannel to be initially displayed when the one-channel broadcasting is switched to the multi-channel broadcasting, and a recording unit for holding the subchannel set via said setting unit, wherein said subchannel control unit controls said transport unit so that when the result detected by said broadcast detecting unit indicates the multi-channel broadcasting, a broadcasting signal including a packet ID corresponding to the subchannel held in said recording unit is outputted.
