Embodiment Construction

[0059] The relay server described in this application uses multiple links to connect to the video source server, which can quickly send fragmented files from the video source server to the relay server, and accelerate the transmission process of live video stream data from the video source server to the relay server. This application segments the live video stream segment file, so that the edge server downloads the data segments of the live video stream segment file from at least two relay servers at the same time, reducing the download delay and eliminating the failure of the relay server. User Service Impact.

[0060] Of course, implementing any technical solution of the present application does not necessarily need to achieve all the above advantages at the same time.

[0061] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clear...

Abstract

The present application provides a live video transmission method, device, and video live broadcast system. When the method of the present application is applied to an edge server, the method includes: requesting index files of live video streams from at least two relay servers at intervals of a first preset period, and determining the data volume of each segment file according to the index files; According to the data volume of the fragment file and the transmission status of each edge server and the relay server, request the data segment of the fragment file to each relay server respectively; receive the fragments downloaded in parallel from each relay server Different data segments of the file; the different data segments are assembled into a complete fragmented file of the live video stream. This application can quickly realize the sending of fragmented files from the video source server to the ultimate server, and at the same time eliminate the problem that some users cannot watch the live video broadcast due to the failure of the relay server.

Description

technical field [0001] The present application relates to the technical field of video transmission, and in particular to a live video transmission method, device, and video live broadcast system. Background technique [0002] With the development of the Internet and computer information technology, live video broadcasting has been increasingly applied to all walks of life. Live video broadcast refers to the use of Internet and streaming media technology to broadcast video source data to customers. [0003] In the early live video application, the video source server packaged the video source data and directly connected to the Internet to provide users with live broadcast services. Customers used client programs or browsers to directly connect to the video source server to watch the live broadcast. With the increasing number of users and the increase in video resolution and quality, the bandwidth of live video has also doubled, and the number of users that a server can serv...
