ABSTRACT:
A digital broadcasting receiver judges whether or not a received program is a data broadcasting program. When the received program is the data broadcasting program, processing for judging a remote control signal from a remote control transmitter is performed as usual. When it is judged that the remote control signal is a remote control signal related to a key associated with channel selection, however, processing corresponding to the signal is not performed. That is, processing for judging whether or not the received program is the data broadcasting program to automatically nullify (lock) a channel change.
