Method and apparatus of multi-image setting

Abstract

The embodiment of the invention discloses a method for setting multi-picture, which comprises the following steps that: a video equipment receives a switching command of a user, wherein the switching command comprises sub-picture information to be switched in the current display mode, and the video equipment switches video sources and sub-picture of the multi-picture screen in the video equipment according to the switching command. The method has the advantages of simplified process of sub-picture setting or switching in the multi-picture setting and improvement of easy operation of the equipment, and no influence on the watching of other sub-pictures when adjusting multi-picture.

Description

technical field [0001] The invention relates to the field of multimedia video communication, in particular to a multi-picture switching method and device. Background technique [0002] In the field of video communication, it is very common for a video terminal to have multiple video input sources, and when a video terminal makes a point-to-point call or participates in a multipoint conference, it also needs to have multiple remote video images. In order to watch multiple video screens at the same time, the user will use the multi-screen function, that is, display multiple sub-pictures on the screen of the video terminal, for example figure 1 The shown video terminal displays a schematic diagram of multiple screens, including: 1, 2, 3, 4, 5, and 6 screens. Of course, there may also be other multi-picture display modes, for example, four pictures symmetrically distributed up, down, left, and right. [0003] In practical applications, the user will adjust the multi-picture mo...

Problems solved by technology

[0007] However, the inventor found in the process of implementing the present invention that this solution is very troublesome when only two sub-pictures need to be simply exchanged.

take again figure 1 For example, when the user wants to switch sub-picture 2 to sub-picture 1 in order to see the content in sub-picture 2 more clearly, the corresponding relationship between the original video source and sub-picture will change, and the above steps must be repeated. Set it once, and reset the video source corresponding to each sub-picture, which is very cumbersome.

And the setting process also affects viewing other sub-pictures, because during the process of setting sub-pictures, the content of the sub-pictures will be temporarily invisible

[0008] In the process of realizing the present invention, the inventor found the following disadvantages in the prior art: the switching process between sub-pictures is cumbersome; it may also affect viewing of other sub-pictures
