Hierarchical model based different-client access audio-video transmission equipment

Abstract

Hierarchical model based different-client access audio-video transmission equipment comprises a remote reliable network access layer, a network signaling parsing layer and an executive layer. The remote reliable network access layer is used for providing reliable signaling transmission with an SIP (session initiation protocol), and directly forwarding a message to the network signaling parsing layer after reliable access is completed during remote network communication; the network signaling parsing layer is used for receiving the signaling message sent from the remote reliable network access layer or a local area network and parsing needed parameters, a signaling includes a message header and a message node identifier, and a needed message is extracted through the message header and the message node identifier and sent to the corresponding executive layer; the executive layer is used for executing corresponding functions according to the parameters sent from the network signaling parsing layer. The hierarchical model based different-client access audio-video transmission equipment is capable of effectively realizing simultaneous accessing of various clients.

Description

technical field [0001] The invention relates to audio and video transmission equipment. Background technique [0002] With the continuous development of society, especially after social security issues have been paid more and more attention by people, the traditional analog video surveillance with one monitoring center and multiple monitoring points can no longer meet the increasingly complex monitoring needs. The entire monitoring industry is constantly developing in the direction of digitalization, standardization, and intelligence, and finally realizes that any authorized person (anybody) can view the surveillance images of any place (anyplace) at any time (anytime) and in any way (anyway). Any method and any location involve access issues of various clients, which mainly include multiple access methods of signaling and multi-destination transmission of media data. [0003] At present, the main audio and video equipment still only provides one access method, which can be...
