ABSTRACT:
In a channel selection device of the invention used in a digital/analog broadcasting receiver, in instructing changing a channel, either one of the UP/DOWN key pair or the RIGHT/LEFT key pair can be used to change a main channel while changing the other pair to change a sub-channel. Thus, by using the keys distributed between the main channel and the sub-channels, a correlation can be given between the key operations and the channels' hierarchical construction to thereby facilitate the changing and selection of the main channels and the sub-channels in the hierarchical construction in digital/analog broadcasts.
