Embodiment Construction

[0020] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] Aiming at the problem of slow and time-consuming transmission of multimedia content such as video in the public network, the present invention designs and implements a multimedia data distribution scheme. The content service node (such as an on-demand server) adopts a logic tree mutual transmission method to transmit multimedia data through the network The platform is quickly deployed to content service nodes.

[0022] The overall design principle is that in a local area (assumed to be a group), only a small number of content service nodes obtain content data from content service nodes outside other groups, and the content service nodes after completing the data acquisition act as peer servers in the P2P structure, and the rest The content service nodes in the group act as peer client 2, and the server provides download...

Abstract

The invention discloses a method and a system of multimedia network transmission based on a tree logic. The system comprises a server and a client; at the server side, the maximum value of file blocks of a file to be transmitted; according to the maximum value, the file to be transmitted into at least one file fragment which comprises at least one file block, and the file block comprises at least one message; a block identification is allocated to each file block and a message identification is allocated to each message; the file blocks are transmitted according to the serial number of each message identification by use of UDP (User Datagram Protocol). According to the technical scheme, the invention provides the method and the system of multimedia network transmission especially suitable for the tress logic, and therefore, the efficiency of the multimedia network transmission can be improved, the utilization rate of network resources can be increased and automatic rate adjustment is easily realized.

Description

technical field [0001] The present invention relates to a multimedia network transmission method and a corresponding system, more specifically, to a tree logic-based multimedia network transmission method and system. Background technique [0002] There are two main ways to disseminate multimedia information on the Internet: downloading and streaming. The download method is a traditional transmission method, which refers to the user downloading multimedia files to the local area before playing. Usually, such files have a large capacity. According to the current network bandwidth conditions, it takes a long time, and there are certain requirements for the local storage capacity. , which limits the use of devices with low storage capacity such as PDAs. Streaming transmission provides multimedia information to the user through the server in real time. In this way, the user does not have to wait for the entire file to be downloaded, but can play it after only a few seconds or te...
