Embodiment Construction

[0021] The basic principle of the present invention is first all TV channels are classified according to the generality of TV channel numbers, and corresponding indexes are set up, such as channel numbers 0, 10, 20, 30, ..., etc., and its commonality is that the channel numbers all include 0, its index is 0, channel numbers 1, 11, 21, 31, ..., etc., its commonality is that the channel numbers all include 1, its index is 1, similarly, channel numbers 2, 12, 22, 32, ..., etc. The commonality is that the channel numbers all include 2, and their index is 2. Therefore, the channel numbers can be classified in advance according to the commonality of these channel numbers. When the user needs to switch TV channels, he only needs to press and hold the target channel Press the button on the remote controller corresponding to the index of the channel number, and the TV will display all the channel numbers with this commonality on the TV screen, and the user can select the target channel ...

Abstract

The invention discloses a method for switching TV channels, which includes the following steps: a. according to a channel index for switching target channels inputted by a user, a TV MCU calls a corresponding channel number list and displays the channel number list on a display screen of the TV; b. the TV microprocessor, MCU, writes channel data corresponding to target channel number selected by the user in the channel number list into a tuner to complete the switching. The invention overcomes the defects in the prior art. So, when the channels are switched by the user, the corresponding channel signal can be rapidly determined according to the channel index, thus saving the time of the user and facilitating humanization experience of the products.

Description

technical field [0001] The invention belongs to the field of television technology, and in particular relates to the technology of television channel switching. Background technique [0002] At present, with the development of the TV industry, more and more channels can be watched on the TV.
