Embodiment 1

[0038] Such as figure 1 As shown, the device for switching TV channels of the present invention includes a storage unit 1 for storing the number of times of play of each channel input by the user daily; to the low sorting, and the sorting result is returned to the sorting unit 2 of the storage unit, the display unit 3 (such as figure 2 shown) and a switching unit 4 for switching videos. Each time the storage unit 1 updates the number of times it stores each channel, after each time the TV is turned on, the sorting unit 2 rearranges the number of times each channel is played from high to low, and re-transmits the sorting results to storage unit 1. When a channel switching instruction is received (such as when the user presses "+", "-" or a specific number), the channel switching instruction is a predefined pulse signal, and a reduced first partial display area is displayed on the display screen. The program dynamic video of the channel (if the channel currently watched by t...

Embodiment 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 play times of each channel input by the user daily;

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

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

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

Embodiment 3

[0050] Such as Figure 6 As shown, on the basis of Embodiment 2, the following steps are also included: S6: When receiving the fast switching instruction, the fast switching instruction can be that the user presses the "+" and "-" buttons on the remote controller for a long time, and the display frequency The above shows a static screenshot of each channel in the first group of channels. The first group of channels includes three channels, and the three channels are the top three channels in the number of broadcasts. For example, channel 10, channel 21, and channel 6 are 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. Thus, when the user wants to switch quickly, the channel whose arrangement position is at the front is preferentially displayed, and the user experience is improved by memorizing the user's habits. : S7: display the program dynamic video of the third channel on the...

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...
