Embodiment Construction

[0042] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0043] Taking the smart TV controlled by the remote control device as an example, the embodiment of the present invention will be further described in detail in conjunction with the accompanying drawings.

[0044] When the TV chip switches channels, the TV signal demodulation process is the most time-consuming process in the entire channel switching process. For example, it usually takes more than 200ms for a TV chip to switch channels onc...

Abstract

The invention discloses a channel switching method. The method comprises the steps: program content of a No.M channel is displayed on a display screen of a smart television; an instruction for long pressing a channel switching key on remote control equipment is received, and a channel number adding one or subtracting one is displayed on the display screen in real time until a channel number N whenlong pressing is ended is displayed; and program content of the No.M channel is directly switched to program content of the No.N channel to be displayed on the display screen. Accordingly, not only can a user see the process that the smart television responds to the channel switching instruction in time, but also channel switching cannot be frequently conducted through a television chip, therefore, the channel switching speed when the channel is quickly switched is increased, the channel switching stability when the channel is quickly switched is improved, and the problems that when the channel is quickly switched, the smart television is slow in response and likely to block are effectively avoided.

Description

technical field [0001] The invention relates to the technical field of televisions, in particular to a channel switching method and an intelligent television. Background technique [0002] Switching channels is one of the most basic and commonly used functions of a TV. For example, when the user presses the channel up button on the remote control device, the TV will switch channels once received by the chip in the TV. When the chip performs a channel switch, it needs to demodulate the TV (television, television) signal through the demodulator, and then switch the channel according to the program information carried in the TV signal. These processes make the chip successfully switch the channel once. slower. [0003] The inventor found that: when the user continuously presses the channel up button on the remote control device, it often appears that the user no longer operates the remote control device, and the TV is still switching channels or freezes, causing the user to b...
