Abstract
In a broadcast receiving system for receiving the digital broadcast, when the selection of “channel selection menu” is inputted by the user, the channel information stored in a memory is read to decide whether the configuration of a sub-channel is identified during the current operation, and a descriptor “x” is assigned to the sub-channel not identified to be made displayed in the channel information list on “channel selection display,” thereby distinguishing it from other channels. This allows the channel whose sub-channel cannot be identified to be OSD displayed distinguishing it from other channels such as for analog broadcast and the like.
