ABSTRACT:
A channel selecting apparatus for television receivers and the like wherein, in case data showing a predetermined channel are stored in a memory (RAM of a channel selecting microcomputer), a first channel selection device provides a tunner with a channel selection controlling signal based on this data. However, in case the data showing the predetermined channel is not stored in the memory, a second channel selection device sequentially provides channel selection controlling signals for receiving respective channels and, when a judging signal showing that a broadcast signal is included in a receiving channel is input from a judging circuit, that channel will be received.
