Live-broadcasting back-to-source method and system

Abstract

The invention discloses a live-broadcasting back-to-source method and system. The method comprises the following steps: sending a back-to-source path query request, receiving a back-to-source path information returned by a scheduling center, wherein the back-to-source path information comprises each layer of path information back to a flow-pushing server from the back-to-source server, and performing back-to-source to the upper layer of server of the back-to-source server according to the back-to-source path information, and sending a request parameter, wherein the request parameter comprisesthe back-to-source path information, and enabling the upper layer of back-to-source server to perform the back-to-source according to the back-to-source path information. The back-to-source path information returned by the scheduling center comprises each layer of back-to-source path information to the flow-pushing server from the back-to-source server, so that the upper layer of back-to-source server except the first layer of back-to-source server is unnecessary to communicate with the scheduling center when performing the back-to-source, the corresponding upper layer of server is directly determined according to the request parameter, the situation that each layer of server needs to communicate with the scheduling center in the prior art is avoided, the communication time is shortened, and the playing delay is further shortened.

Description

technical field [0001] The present invention relates to the field of live broadcast control, in particular to a method and system for live broadcast back-to-source. Background technique [0002] In the live video backend architecture, a hierarchical network structure is usually used, such as figure 1 shown. Among them, the streaming server is the server where the anchor uploads live content in real time, and the playback server is the server where the user finally watches the live broadcast, with one or more layers of relay servers in between. [0003] When a user accesses the playback server, the playback server may not have relevant live content. At this time, it is necessary to download the relevant live content from the relay server to the higher-level relay server until the streaming server requests it. This process is back to the source. [0004] Currently, the commonly used back-to-source method usually requires the back-to-source server to query the back-to-source ...

AI Technical Summary

Problems solved by technology

[0005] In view of this, the present invention provides a method and system for live broadcast back-to-source to solve various problems caused by all servers on the back-to-source path in the prior art needing to communicate with the dispatching center to inquire about the path to the upper layer. The communication time between the super-level server and the dispatching center is too long, which causes a large delay. The specific solution is as follows:
