Abstract
In a broadcasting signal processor, an automatic channel memory device for determining whether a broadcasting signal is present in a channel tuned according to user's selection, and for automatically memorizing the tuned channel if a broadcasting signal is present in the tuned channel, is provided. A user's selected broadcasting channel can be accurately stored in a memory without using a separate memory button, thereby simplifying key operation.
Claims21
A channel memory device in a broadcasting signal processor, comprising:
- a key input for inputting a channel number according to a user's selection;
- a tuner for tuning to the channel corresponding to the channel number selected by the key input, among received broadcasting signals;
- a signal processor for processing a composite video signal of said channel tuned and output from the tuner;
- a memory for storing the channel number;
- and
- a controller for receiving the channel number output from the key input and storing the channel number output from the key input in the memory while controlling the tuner to tune to a broadcasting channel corresponding to the received channel number,
- wherein the controller receives a signal output from the signal processor, determines whether a broadcasting signal is present in the currently tuned broadcasting channel and stores the corresponding broadcasting channel number in the memory only if said broadcasting signal is present.

A broadcast signal receiving device comprising:
- a remote control unit having a plurality of buttons for inputting a channel number according to a user's selection;
- a tuner for tuning to a channel of the channel number selected on the remote control unit by a user, among received broadcast channels;
- a signal processor for processing a signal of the channel tuned and output from the tuner;
- a channel map memory for storing memorized channels;
- and
- a controller for storing the channel number in the channel map memory without receiving two or more input operations on the remote control unit by a user in selecting the channel number on the remote control unit for the tuning to the channel and storing the channel number in the channel map memory, if the controller determines that a broadcast signal is present in the tuned channel,
- wherein the tuned channel is not an automatically scanned channel.
