Embodiment Construction

[0031] In this embodiment, a streaming media server on a set of desktop PCs is implemented to provide video-on-demand services to the streaming media player on the Pocket PC. The goal is to complete the basic server and expand the platform. PDA can use symmetric coding technology to complete the transmission after video acquisition; at the same time, it allows functions such as rate control, transcoding, and application layer multicast to be added to the server. And complete the proxy server. The communication between the server and the player adopts communication protocols based on RTP, RTCP, and RTSP; among them, in the RTSP protocol, the format information of the streaming media is transmitted through the SDP protocol. This video-on-demand system is compatible with streaming media player RealPlayer, that is, users can use RealPlayer on common IBM PC compatible machines to communicate with streaming media servers. For this purpose, the server follows the communication proto...

Abstract

This invention relates to visual frequency play system and method based on wireless local network, which comprises interface wireless local network flow media servo and at least customer end by use of RTP, RTCP and RTSP agreement communication, wherein, the servo adopts single wire process servo; the customer end adopts PDA with each composed of one task manager through its task manager transfer to fulfill customer end RTP data receive and RTCP report receive and send.

Description

technical field [0001] The invention relates to a system and method for providing information services, realizes a set of video-on-demand system under the environment of wireless heterogeneous local area network, and proposes several methods for optimizing streaming media playing effect under the condition of wireless heterogeneous local area network. Background technique [0002] With the development of computer multimedia technology and network technology, streaming media playback technology has been widely used. This technology allows viewers to watch multimedia programs online, so that a series of functions such as video on demand and video conferencing can be realized. Among the open source software for video servers, RealNetworks' Helix Server and Apple's Darwin Stream Server are widely used, have high stability and excellent performance, but have a large amount of code and complex structure, and are not suitable for structural improvement. , the scalability is relati...
