Accordingly, they are watching current events, sports, life information, education, and entertainment programs through various broadcasting channels.

As the number of broadcasting channels increases, the television detects the synchronization signal of the received composite video signal, and automatically receives the channel information that can be received, and stores it as a channel map. The broadcasting channel stored as the channel map is stored in the channel of the remote controller. According to the / down key input, it is shown on the display in the order stored in the channel map.

In the automatic channel information search of a television, all channels provided for searching for a channel for receiving a broadcast signal are searched to configure a channel for receiving the broadcast signal as a channel map. In addition, if the automatic search function of the channel information is executed again in the state in which the channel map is configured, the newly searched channel is configured as the channel map while the channel map set as the reference is deleted.

In the conventional television as described above, all channels provided are automatically searched when the channel information automatic search function is performed, and thus, a long time is required to search the channels.

In addition, when the automatic channel information retrieval function is performed, the re-discovered channel is configured as the channel map while the previously stored channel map is removed, which makes it difficult to search or select a specific channel.

The present invention has been made to solve the above-described problems, and by setting the channel section to be searched by the user and automatically searching the channel in the set channel section, the channel of the television that can shorten the channel search time The purpose is to provide a setting method.
