Abstract
In a broadcast receiving system for receiving the digital broadcasting, when the selection of “channel addition/deletion menu” is inputted by the user, received broadcasting signals are decoded to obtain collectively the channel information of the digital/analog broadcasting. This channel information is compared with channel information made stored in a memory to distinguish the channel having suspended from the channel having been resumed, and the distinguished information is made OSD displayed for each channel. The user operates an input device to select a desired channel, and inputs an instruction of the channel addition/deletion with an addition button or a deletion button to update the data stored in the memory. In this way, the display of the channel information of the digital/analog broadcasting transmitted from the same or the same-system broadcasting station is made displayed continuously and mixedly, thereby making it possible for the user to understand visually a transition in channel configuration.
