Live broadcasting time shifting system based on P2P (peer-to-peer) technology and method thereof

Abstract

The invention discloses a live broadcasting time shifting system based on a P2P (peer-to-peer) technology and a method thereof. The system comprises a code server, a live broadcasting sever and a control server which are arranged at a server side. The method comprises the following steps of: cutting live broadcasting video data received into live broadcasting video data packets with fixed size by the code server, and then adding live broadcasting channel information and time information into each live broadcasting video data packet, distributing the coded live broadcasting video data packets to the live broadcasting server, and sending the current control information to the control sever; continuously acquiring the live broadcasting video data packets from the code server by the live broadcasting video sever; when a client side applies for watching videos, firstly sending a video request to the control server, returning the storage information of the video data to the client side by the control sever, and acquiring the video data through the established data chain path by the client side. The server side and the client side of the invention can simultaneously support the live broadcasting time shifting function based on the P2P technology and support the large-scale concurrent application.

Description

technical field [0001] The invention belongs to the technical field of network video transmission and application, in particular to a video transmission technology combining P2P technology and live broadcast time-shifting technology. Background technique [0002] Live video technology has been widely used, and television is a widely used live video technology. The live video technology is characterized by timeliness, and if you miss the time, you cannot watch the live video content. For customers who want to watch live video content, but the time cannot be guaranteed, either wait for the re-live video content, or use the on-demand method to watch the video content. However, whether live video content is rebroadcast, whether it can become on-demand video content, and the online time of on-demand video content cannot be determined. In order to meet customer needs, a technology for storing live video content has emerged. This storage can be implemented on the server or throug...

AI Technical Summary

Problems solved by technology

[0010] In the published P2P live broadcast technical data, the length of the server-side memory buffer is usually at the second level, generally within 150 seconds, because the length of the memory buffer will affect the playback time delay of the live video of the client terminal, and the increase of the time delay will Affect the customer's viewing effect
