Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.

[0026] In order to solve the problem of how to control the switching of the streaming end of the host and the guests described in the background technology section, the inventor considered three ways of switching the live stream of the streaming end:

[0027] 1. Push the flow in turn in sequence. That is to ensure that there is only one streaming terminal at the same time. When it is necessary to switch the lecture screen, the current lecturer stops streaming, and the next lec...

Abstract

The invention relates to a multipath live broadcast stream switching device, method and system, and the device comprises a live broadcast stream address scheduling unit, a live broadcast stream access unit, a live broadcast stream collection unit, and a matrix management unit. The live broadcast stream address scheduling unit marks live broadcast stream recognition information for the multiple paths of live broadcast streams and allocates corresponding live broadcast stream access units for the multiple paths of live broadcast streams, and the live broadcast stream recognition information comprises a target address for collecting the live broadcast streams; the live broadcast stream access unit forwards the multiple live broadcast streams to the corresponding live broadcast stream collection units according to target addresses of the multiple live broadcast streams, and collects and uploads related state information of the multiple live broadcast streams to the matrix management unit; the matrix management unit determines whether to switch the live broadcast streams according to the related state information of the multiple live broadcast streams; and the live broadcast stream collection unit outputs a target live broadcast stream specified by a switching instruction according to the live broadcast stream switching instruction of the matrix management unit. According to the scheme of the invention, switching of multiple paths of live broadcast streams can be realized conveniently and quickly.

Description

technical field [0001] The present application relates to the field of audio and video live streaming, and in particular to a multi-channel live stream switching device, method and system. Background technique [0002] At present, in the general live broadcast application scenario, it includes the capture of images and sounds at the streaming end, encoding at the streaming end, network transmission at the streaming end, transcoding and distribution of the live stream by the server cluster, pulling streams at the viewing end, decoding and decoding at the viewing end. rendering process. In this process, even if there are multiple streaming terminals, the content of a live streaming address can only contain the images and sounds collected by one streaming terminal, and neither the streaming terminal nor the viewing terminal can be flexibly selected and switched. For example: the streaming end of a live broadcast includes a host streaming end and a guest streaming end, and the ...
