Embodiment Construction

[0023] The Peer-to-Peer architecture design method for real-time transmission of streaming media with digital copyright management under a heterogeneous IP network provided by the present invention can realize real-time transmission of streaming media in a P2P heterogeneous network, satisfying streaming media transmission network services and users demand. Specifically include:

[0024] 1) Realize the encryption operation of streaming media content through "encryption" technology;

[0025] 2) Realize digital copyright management of streaming media content, Peer authentication and key distribution operations through the "P2P architecture of authentication server" technology;

[0026] 3) Through the "distributed index server P2P architecture" technology to achieve streaming media Peer information management and Peer Buffer sharing information and other operations;

[0027] 4) Through the "Peer program clustering" technology, realize the user management and sharing of the same ...

Abstract

The invention discloses a method for designing the network transmission structure of P2P streaming media with digital rights management, comprising the following steps of using encryption technology to encrypt the steaming media in real time for realizing copyright protection of the digital content; using a certificate server to realize the Peer management, authentication, authorization of P2P network; using an index server to realize the Peer management, clustering, selection and shared service and so on; using Peer clustering technology to enable the heterogeneous Peers broadcasting the same program source to supply downloading and uploading service therebetween; using distributed Super Node to store the streaming media source; using Peer Buffer management technology to realize uploading and downloading service among heterogeneous Peers; and using scheduling algorithm to realize Block-stage parallel downloading. The Peer can be a client or a server, which can sufficiently utilize the resource among Peers and greatly reduce the load of the server, thereby realizing the real-time transmission of the streaming media with a better quality. The invention can meet streaming media network transmission service and real-time requirement for Peer of users.

Description

technical field [0001] The invention belongs to the field of video coding and network transmission. Specifically, it relates to an architecture design method of P2P (Peer-to-Peer) real-time transmission of streaming media with digital rights management in heterogeneous IP networks. Background technique [0002] The P2P distributed network transmission structure has changed the traditional streaming media transmission and playback mode - Client / Server centralized network mode, which makes full use of idle storage resources between clients, balances the load of streaming media network media servers, and increases the number of supported customers Quantity, real-time and load balancing of the entire live streaming or on-demand transmission network. However, using a pure P2P distributed network transmission structure, its user Peer management and digital media content copyright management are the main problems faced by streaming media P2P live or on-demand, which limits the app...
