P2P live-broadcasting video-on-demand system

Abstract

The invention discloses a P2P live-broadcasting video-on-demand system, which comprises a live-broadcasting system and a video-on-demand system. The live-broadcasting system comprises acquisition equipment, director equipment encoder, a P2P live-broadcasting platform, a file server, an introduction server, a remote publishing point, a super node server and video live-broadcasting equipment. An output end of the acquisition equipment is connected with an input end of the director equipment encoder, and an output end of the director equipment encoder is connected with an input end of the P2P live-broadcasting platform. By acquisition of data from other users through P2P, watching delay and bandwidth use ratio can be regulated manually to solve the problem of video quality reduction caused byhigh server resource and bandwidth pressure due to user increase; by adoption of minimum byte streams, excessive load on servers is avoided; by means of dynamic bandwidth detection, all audiences using the P2P service are capable of setting an upper limit of uploading; video files are not stored in clients during live broadcasting, so that disk space occupying is avoided.

Description

technical field [0001] The invention relates to the field of video playing systems, in particular to a P2P live on-demand system. Background technique [0002] At present, the playback mode of domestic mainstream websites is generally FLASH playback mode. The main advantage is that IE itself integrates the FLASH playback plug-in, so users only need to use the Windows platform to use IE to watch FLASH live on-demand videos. A very low threshold is very good for attracting new users to join the website, but the disadvantages are also obvious. While the number of users is gradually increasing, the bandwidth also shows a sharp increase. As we all know, the current domestic server bandwidth rental fee is quite expensive. This has also become the biggest problem facing the development of small video websites. [0003] Therefore, it is necessary to invent a P2P live on-demand system to solve the above problems. Contents of the invention [0004] The purpose of the present inven...

AI Technical Summary

Problems solved by technology

[0006] In the live broadcast system, the user preferentially obtains data from other users through P2P, thereby solving the problem of heavy pressure on server-side resources and bandwidth, and reduced video quality after the number of users increases. The super node server is used for users to manually adjust the viewing delay. The ratio of time and bandwidth usage ensures that the delay effect of the user is less than 30s at any time;
