Channel switching method, television terminal and remote control device

Abstract

The embodiment of the invention discloses a channel switching method, a television terminal and a remote control device, relating to the technical field of television. The invention aims at solving the problems that the remote control device has many function keys and complex operation, and the television terminal has heavy processing burden. In the embodiment of the invention, the channel switching method comprises the following steps of: receiving a keyboard-generating instruction transmitted by the remote control device; generating and displaying a virtual keyboard and a selection cursor according to the keyboard-generating instruction, wherein the virtual keyboard comprises a numeric key and a channel frame, or the virtual keyboard comprises the channel frame; defining numbers corresponding to the target channel one by one according to an instruction which is inputted by a user with the virtual keyboard and the selection cursor through the remote control device; and switching the current channel to the target channel if receiving the instruction that the current channel is switched to the target channel. Therefore, the invention can switch the channels under the condition that the remote control device does not set the numeric key, reduces the amount of the keys of the remote control device, increases the use convenience, and reduces the processing burden of the television terminal.

Description

technical field [0001] The invention relates to the technical field of television, in particular to a channel switching method, a television terminal and a remote controller. Background technique [0002] With the continuous development of TV broadcasting technology and digital TV, more and more TV programs can be received by the TV set, and often hundreds or even more TV programs can be received. [0003] At present, users can switch channels by pressing the number keys set on the remote control. When channeling, the user can press the corresponding number key, and after the TV receives the signal, it will decode to obtain the corresponding code value and store it. If the signal of pressing the number key again is not received within the preset time (such as 3 seconds), Then read the code value from the memory as the target channel, and switch the channel to the target channel. [0004] When the user needs to switch to a two-digit channel, such as a channel of 10-99, the ...

Problems solved by technology

[0006] However, the inventor finds that the solution has the following defects in the process of realizing the present invention: with the rapid development of multimedia interactive TV, the operation of TV functions becomes more and more complicated, and there are more and more buttons on the remote controller. As the number increases, the ease of use of the remote control (including when doing channel switching) becomes less and less

In addition, when the user switches to a two-digit, three-digit or even multi-digit channel, the TV needs to decode, judge, store, and read the stored code value multiple times, which increases the processing burden of the TV.
