Video live broadcast method and system based on HTTP (Hyper Text Transport Protocol)

Abstract

The invention provides a video live broadcast method and a system based on an HTTP (Hyper Text Transport Protocol). The video live broadcast method comprises the following steps of: dividing a live video stream into a plurality of slice files by a live source server; synchronously downloading the slice files from the live source server through the HTTP by an edge server; assembling the slice files into a complete file by the edge server; and providing a video live service of the complete file for the client through the HTTP. Therefore, according to the a video live broadcast method and system disclosed by the invention, the stability of the live video stream can be effectively improved, the multi-machine load balance is easily realized and the technical support for late-stage backup or processing of the live video stream is provided.

Description

technical field [0001] The present invention relates to the technical field of Internet video live broadcasting, in particular to a method and system for live video broadcasting based on the HTTP protocol. Background technique [0002] Internet video live broadcast is to use the Internet to push the video signal being played to the client through a specific method, and the player of the client will display the video signal as a visual and audible video. Generally, there are two options for the client: a custom client and a browser-based thin client. Customized clients have a high degree of freedom. Live video providers can use their own specific video transmission protocols, while thin clients choose open protocols, such as HTTP (HyerText Transport Protocol, Internet Transmission Protocol), RTSP (Real Time Streaming Protocol, Real-time Streaming Protocol), RTMP (Real Time Messaging Protocol, Real-time Message Transmission Protocol), etc. Taking the commonly used RTSP techn...

AI Technical Summary

Problems solved by technology

[0003] 1. The server needs to respond to the client's instructions in real time, resulting in a high load on the server;

[0004] 2. The logic of the server and client is relatively complex;

[0006] 4. The live broadcast content of the server will not be saved, which is difficult to use for post-processing;

[0007] 5. Use a dedicated port, which is easily blocked by the firewall;

[0008] 6. In the multi-machine load balancing architecture, the connection between the live broadcast source server and the edge server must be maintained. If the connection is interrupted, the service content will be interrupted.

[0009] In summary, the existing Internet video live broadcast technology obviously has inconvenience and defects in actual use, so it is necessary to improve it
