Abstract

The invention discloses an on-line video-on-demand system based on P2P, comprising a server terminal and client terminals. The server terminal comprises a secret key providing server, a Tracker server of the BT protocol, and an NAT boring server. Each client terminal is composed of a Proxy process and a player process. Each Proxy process establishes connection with the Tracker server of the BT protocol and an Internet through a BitTorrent P2P protocol so as to obtain encrypted video data. Each player process communicates with the Proxy process through a hyper text transport protocol (HTTP) and communicates with the secret key providing server through hyper text transport protocols (HTTPS) to obtain a secret key. The Proxy processes also communicate with the NAT boring server which is in charge of NAT traversal communication with the two client terminals. The on-line video-on-demand system based on P2P performs one-time static encryption of video files at a background, and distributes the video files to users through P2P; and secret keys required for videos on demand are obtained from the secret key providing server.

Description

technical field [0001] The invention belongs to the technical field of video-on-demand for educational applications, and in particular relates to a P2P-based online video-on-demand system. Background technique [0002] With the continuous development of science and technology, video-on-demand technology is widely used in major media, and it is also popularized in the field of education. The core role of video in education is recognized by everyone; it can present sound and picture at the same time, which can Achieve 90% of the effect of on-site interactive teaching; coupled with instant messaging on the Internet, social network interaction and interpersonal contact, Internet-based distance education with video as the main content carrier, social networking, etc., and instant messaging as the main means of communication are constantly increasing. developing. [0003] Existing video technologies in the IT industry are all focused on traditional TV movies and other content. Vi...
