Embodiment 1

[0029] The existing implementation method is to do separate rendering for each video output, which consumes relatively large resources, and when there are video screens superimposed, it is prone to display abnormalities

[0030] Such as figure 1 As shown, this embodiment provides a multi-channel video window overlay display method, including the following steps:

[0031] S1: Receive the video signal sent by multiple video outputs, and obtain the display position of the corresponding video signal; specifically, when operating the video channel of the video decoder on the client side, often due to the limited interface size, multiple The video output windows are stacked together; at this time, it is necessary to obtain all the video signals and the display positions of the video signals on the display page. The multiple video outputs are two video outputs or three video outputs or four video outputs.

[0032] After step S1, step S11 is further included: determining the size an...

Embodiment 2

[0049] Embodiment 2 discloses an electronic device, which includes a processor, a memory, and a program, wherein one or more processors and memories can be used, and the program is stored in the memory and configured to be executed by the processor, When the processor executes the program, a multi-channel video window overlay display method in Embodiment 1 is realized. The electronic device may be a series of electronic devices such as a mobile phone, a computer, and a tablet computer.

Embodiment 3

[0051] Embodiment 3 discloses a computer-readable storage medium, which is used to store a program, and when the program is executed by a processor, the multi-channel video window overlay display method of Embodiment 1 is realized.

Abstract

The invention discloses a multi-channel video window overlapping display method, which comprises the following steps of: receiving video signals output and sent by multiple channels of videos, and acquiring display positions of the corresponding video signals; judging whether the multiple paths of video signals are overlapped or not according to the display positions of the video signals; selecting one of the images with the overlapping area to be overlapped with the video signal without the overlapping area to form an image to be rendered; and performing unified rendering on the obtained to-be-rendered images and projecting the to-be-rendered images to a display page for a user to watch. The invention further provides electronic equipment and a computer readable storage medium. Accordingto the multi-channel video window overlapping display method disclosed by the invention, the overlapping result can be displayed by combining the overlapped video inputs of the multi-channel display window together and then only performing output rendering once; the method disclosed by the invention has the advantages of higher processing speed and lower video output delay; the method can effectively solve the problem of abnormal display of the overlapping part of a high-resolution video window.

Description

technical field [0001] The invention relates to the technical field of video playback, in particular to a multi-channel video window overlay display method, electronic equipment and a storage medium. Background technique [0002] In the existing video decoding box, each video output window needs to be rendered separately to display, which not only consumes computing resources, but also causes a large video delay. If multiple output windows overlap on the 4K video display, it will often cause abnormal display of the overlapping parts, such as skipping screens or blurred screens. Therefore, providing a display solution with faster processing speed and lower video delay has become a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, one of the objectives of the present invention is to provide a multi-channel video window superimposed display method, which can solve th...
