Method for storing VOD medium of equity network and media demanding system thereof

Abstract

The invention discloses a storage method of a peer-to-peer network video on demand media, and the steps comprise: a media document is segmented; at least one office end node is introduced, and segmented for saving an original copy of the media document; user nodes and the office end node are divided into districts according to geographical districts, each district carries out the management of the stored segmented media on the user nodes and the office end node of the district through a media gateway; and the user nodes call the segmented media document on various office end nodes of the district to constitute the media document to be played. The invention further discloses a peer-to-peer network media on demand system. As the media document is segmented, the user node does not need to store the whole media document and only needs to store certain segmented media document, that is, a plurality of user nodes are collaborated to complete the storage of the big media document, thereby effectively reducing the media recording costs and the storage costs of the user nodes.

Description

technical field [0001] The invention relates to a peer-to-peer network (Peer To Peer Network, hereinafter referred to as P2P) and broadband streaming media technology, in particular to a method for storing video-on-demand media on a peer-to-peer network and a media-on-demand system. Background technique [0002] With the rapid development of the Internet and broadband access networks, the use of P2P technology has been able to successfully carry out large-scale video media downloads and live broadcasts on the Internet. However, there are still many problems in the large-scale development of P2P on-demand services, among which media storage is one of the problems. [0003] In the existing P2P on-demand system, there are mainly the following two storage solutions: [0004] 1. The original upload node saves a complete piece of media data. General user nodes do not store media data on the disk, but only cache a small part of the data in memory during playback. User nodes can on...

AI Technical Summary

Problems solved by technology

[0006] The main problem of the first solution is that the number of shared nodes is too small, and if the original upload node is not online, the network cannot provide the media service at all

Although the second solution solves the problem of the first solution, it needs to record while watching, and the processing and storage costs are also very high, which is likely to cause the user's disgust, and then cause the user to delete or transfer the recorded media after watching. content

Therefore, it is not an ideal storage solution

At the same time, neither of the two schemes can guarantee that the published content can get guaranteed service, and only when the user with the content is online, other users can get the content service
