Example Embodiment

[0037] Example 1

[0038] Such as figure 1 As shown, the device for switching TV channels of the present invention includes a storage unit for storing the number of times each channel is played by the user daily input, and the number of times of each channel is higher according to the number of times each channel is played. To low sorting, and return the sorting result to the sorting unit 2 of the storage unit 2, the display unit 3 for displaying the dynamic video of the first channel on the display screen (such as figure 2 Shown) and a switching unit 4 for switching video. Each time the storage unit 1 updates the number of broadcasts of each channel stored in it. Every time the TV is turned on, the sorting unit 2 reorders the number of broadcasts of each channel from high to low, and returns the sorting results to Storage unit 1. When a channel switching instruction is received (for example, when the user presses "+", "-" or a specific number), the channel switching instructio...

[0042] Example 2

[0043] Such as image 3 As shown, the method for switching TV channels used in the above-mentioned device for switching TV channels of the present invention includes S1: storing the number of times each channel is played daily input by the user;

[0044] S2: According to the playing times of each channel, sort the playing times of each channel from high to low, and return the sorting result to the storage unit;

[0045] S3: Display the program dynamic video of the first channel on the display screen in full screen;

[0046] S31: When a channel switching instruction is received (for example, when the user presses "+", "-" or a specific number), the channel switching instruction is a predefined pulse signal, and the reduced size is displayed in the first partial display area on the display screen. The program dynamic video of the first channel (if the user is currently watching channel 2, the first partial display area displays the reduced dynamic video of channel 2),...

Example Embodiment

[0049] Example 3

[0050] Such as Image 6 As shown, on the basis of Embodiment 2, the following steps are further included: S6: When a fast switching instruction is received, the fast switching instruction can be that the user long presses the "+" and "-" buttons on the remote control to display the frequency The static screenshots of the programs of each channel in the first group of channels are displayed on the top. The first group of channels includes three channels, which are the top three channels in the order of play times, such as channel 10, channel 21, and channel 6 The top three channels, such as Figure 7 Shown. The fast switching command is that the duration of the pulse signal exceeds the first threshold. Therefore, in the case that the user wants to switch quickly, the channel that is arranged in the front position is preferentially displayed, and the user experience is improved by memorizing user habits. : S7: Display the dynamic video of the third channel and ...

Abstract

The invention discloses a device and a method for TV channel switching. The device comprises a storage unit which is used for storing the number of broadcast times of each channel input by a user daily, a sorting unit which is used for sorting the channels in order of the number of broadcast times from largest to smallest according to the number of broadcast times of each channel and sending the sorting result back to the storage unit, a display unit which is used for displaying the program dynamic video of a first channel on a whole display screen, and a switching unit which is used for switching the program dynamic video of the first channel displayed in a first local display area to all program static screenshots of the first channel and switching the static screenshots of a second channel displayed in a second local display area or the static screenshots of any channel displayed in a third local display area to a program dynamic video corresponding to the channel. The black screen phenomenon appearing in the process of TV channel switching is avoided, and the problem that a channel often watched by users at ordinary times cannot be located quickly is solved.

Description

technical field [0001] The invention relates to the field of television, in particular to a device and method for switching television channels. Background technique [0002] When watching TV programs, users need to constantly switch channels to find interesting program content. Channel switching is a high frequency task scenario in live TV. The user usually uses the channel switching keys (upper channel, next channel) of the remote controller, or uses digital keys to switch channels. [0003] In the existing channel switching method, the user controls the TV to switch channels by clicking a switch key or a digital key on a remote controller. When the user presses the channel switching key for a long time, the TV can be controlled to perform fast channel switching. [0004] In the process of switching channels, because the system cannot display two or more high-definition live channel video streams at the same time, it is necessary to wait for the system to complete the t...
