Embodiment Construction

[0025] The present invention provides a P2P streaming media broadcasting method for multimedia phones, which is a protocol process for realizing P2P streaming media broadcasting based on a fixed multimedia videophone terminal. The core is how to produce and maintain an application with a media source as the root node Layered P2P streaming multicast tree.

[0026] The core of the protocol that generates the multicast tree is: set up the application layer multicast tree from a media source to some multimedia telephony terminals as the main broadcast path (see figure 1 ), the media source is the root node of the multicast tree, part or all of the tree nodes in the multicast tree are super tree nodes, and the super tree node is composed of one or more nodes identical to its intranet Partnership, each node in the partnership uses P2P communication, and the multimedia phone terminal requesting streaming media service preferentially joins the partnership of the same super tree node a...

Abstract

The invention relates to a peer-to-peer (P2P) stream media broadcast method for a multimedia telephone. The method comprises a step of: establishing an application layer multicast tree serving as a main broadcast route from one media source to a plurality of multimedia telephone terminals, wherein the media source is a root node of the multicast tree; partial or all tree nodes of the multicast tree are super tree nodes; the super tree nodes and one or more nodes which are the same as an internal network of the super tree nodes form a partnership; and nodes in the partnership communicate with one another in the partnership by adopting a P2P mode. The terminal which requests service is preferentially added into the partnership of the super tree node which is the same as the internal networkof the terminal or preferentially constructs a new partnership with a tree node which is the same as the internal network of the terminal and serves as the super tree node; and a system based on the method provides a support for implementing the method in software and hardware aspects. By adopting the method or the system, the network routing efficiency can be improved and the pressure on a backbone network can be relieved; and the method is a feasible P2P multimedia broadcast scheme which has high economy and high comprehensive broadcast performance and is easy to popularize and apply.

Description

technical field [0001] The present invention relates to a streaming media P2P broadcasting method and system realized based on multicast tree broadcasting technology, in particular to a method and system for realizing P2P streaming media broadcasting based on a fixed multimedia videophone terminal, the core of which is how to establish and maintain An application layer P2P streaming media multicast tree with the media source as the root node. Background technique [0002] Embedded multimedia videophones with large screen and multi-service functions have entered thousands of households. In order to promote value-added services, especially advertising / entertainment media services based on videophones, such as TV broadcasting, video on demand, and multimedia advertising push, etc. When it comes to streaming media broadcasting technology covering the Internet, it needs the support of corresponding software and hardware. [0003] As the broadcasting terminal of streaming media, ...
