Problems solved by technology

Even if you use the search tags, users have to manually search the tags one by one, which still seems time-consuming and troublesome
If there are so many programs that it is impossible to list them one by one on the label on the back of the remote control, then even if you use a special channel and TV station comparison table to check them one by one, it will still be time-consuming, and users will hardly accept this method.

Abstract

This invention discloses a remote controller to search and select TV channel quickly. Wherein, adding a second micro processor (MCU2), a keying circuit (2), a switch selecting circuit (7), and modulated remote control signal detection circuit (4). The corresponding method comprises: 1) building and storing relation between channel number and channel name in the controller; 2) receiving the input channel name directly; 3) finding out the channel number; 4) the remote controller sends out the channel signal. The invention benefits user not to remember the relation and switches channel easily.

Description

【Technical field】 [0001] The invention relates to a method for searching and selecting TV channels and a TV remote controller thereof. 【Background technique】 [0002] At present, the number of channels that can be received by cable television is increasing. At the same time, in order to meet this demand, TV manufacturers have developed TVs that can store up to hundreds of channels. Faced with dazzling programs, users can get more While having too much information, also feel at a loss, because the user can't remember the corresponding channel number (station number) of each TV channel (station name). When the user needs to watch a certain TV program, he often forgets which channel number to save on the TV, and can only switch and search the channels one by one until he finds the target channel, which is very time-consuming and extremely inconvenient to use; and the TV remote control The device frequently transmits signals, which consumes a lot of power; while the TV frequent...
