Problems solved by technology

The advantage is that there is a small video channel preview during the program switching process. The disadvantage is that the small videos are pre-edited and arranged by the background server, and the order of the program arrangement is also fixed, so the efficiency of program selection is low, and users cannot flexibly edit and navigate through their own preferences. For small videos, it is impossible to quickly switch to the target program, the flexibility is poor, and it cannot be personalized

Embodiment Construction

[0036] The present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0037] figure 1 It is a block diagram of the network structure of the digital TV in this embodiment. The background server 11 sends the digital TV program data to the set-top box 12 in the foreground, and the set-top box 12 decodes the received digital TV program data and plays it on the TV 13 .

[0038] figure 2 It is a structural block diagram of the channel switching system in this embodiment. The system includes an initiating device 21 , an output device 22 , a switching device 23 and a storage device 24 .

[0039] The initiating device 21 is used for initiating a channel switching request. The output device 22 is used to superimpose the home page of the channel switching interface on the TV currently playing the program screen after receiving the channel switching request; Program video preview. The switching device 23 is used to sele...

Abstract

The invention discloses digital television channel switching method and system, belonging to the technical field of digital television set-top boxes and solving the problems of channel switching blindness and lower efficiency of a traditional channel switching mode. The method comprises the following steps of: firstly, initiating a channel switching request, overlaying a channel switching interface home page on a current playing program picture, dividing the home page into a plurality of display areas, and displaying the program video preview of latest viewed channels in each display area; then, selecting and confirming a channel to be switched on the channel switching interface and finishing channel switching; and finally, storing a channel switching operation record. In a mode of displaying the program video preview of the latest viewed channels on the channel switching interface home page, the invention overcomes the channel switching blindness and improves the efficiency without influencing the normal playing of the current program.

Description

technical field [0001] The invention belongs to the technical field of digital TV set-top boxes, and in particular relates to a digital TV channel switching method and system. Background technique [0002] At present, the common ways for the digital TV set-top box to switch programs include the following five. [0003] Method 1: Input the logical channel number of the target channel through the <number keys> on the remote control to switch to the target channel directly. The advantage is that it can switch to any channel. The disadvantage is that it is difficult to memorize the logical channel number of the program, and it is impossible to predict whether the program content of the target channel meets the user's viewing needs, which has the blindness of channel switching. [0004] Method 2: Use <Up / Down Key> or <P+ / P-Key> to switch channel programs one by one until switching to the target program. The advantage is that the method is simple, and the disad...
