Embodiment Construction
[0054] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0055] One of the core ideas of the embodiment of the present application is that during the multi-stream video live broadcast process, the user-designated main screen video is played in high definition, and other videos (split-screen videos) are played in low definition. .
[0056] refer to figure 2, which shows a flow chart of the steps of Embodiment 1 of a control method in a multi-stream video live broadcast of the present application, which may specifically include the following steps:
[0057] Step 101, receiving a multi-stream live video request submitted by a client;
[0058] Step 102, generating screen layout information of multiple channels of video according to the multi-stream video live b...

The invention provides a control method and device used in multi-stream live video broadcast. The method comprises the following steps: receiving a request which comprises a multi-stream video live broadcast request and is submitted by a client side; according to the request, generating picture layout information of multiple videos, which comprises main picture video information and subsidiary picture video information that are generated according to the multi-stream video live broadcast request; returning corresponding multiple video streams according to the picture layout information of the multiple videos, particularly, returning corresponding video streams in a first definition according to the main picture video information and returning corresponding video streams in a second definition which is lower than the first definition according to the subsidiary picture video information. By adopting the control method and device, the requirement for different definitions of all videos of users are satisfied and bandwidth occupation and resource consumption are reduced.
Description
technical field [0001] The present application relates to the technical field of video processing, and in particular to a control method in multi-stream video live broadcast, a control device in multi-stream video live broadcast, a multi-stream video live broadcast server, and a multi-stream video broadcast device. Background technique [0002] Multi-stream video live broadcast can be understood as playing multiple video streams in one screen at the same time, that is, playing multiple videos for users on the same screen at the same time. refer to figure 1 The picture diagram of the multi-stream video live broadcast shown in the figure generally includes a main screen and multiple sub-pictures. Each main picture and sub-pictures play different videos respectively. Layout and control of the screen, select which channels of video to play, switch a certain channel of video as the main screen, or close a certain channel of video. [0003] In the existing multi-stream video li...
