Data exchange method based on video boundary

Abstract

The invention provides a data exchange method based on a video boundary. The method includes steps: configuring at least a real service terminal, a channel service terminal, a channel client terminal,and at least a real client terminal; receiving request information transmitted by the channel service terminal and returning corresponding response data by each real service terminal; configuring a plurality of mapping ports at the channel client terminal, and transmitting a request to the corresponding mapping port and receiving the response data by each real client terminal; and configuring anSIP text channel between the channel service terminal and the channel client terminal as a data interaction mode. Transparency processing of a session initial protocol (SIP) of the video boundary is performed, standard protocol conversion of the video boundary is performed in the method, and the change of the protocol fails to be sensed during data transmission of transmitting and receiving terminals. The restriction of the video boundary is logically filtered, the development efficiency of cross-boundary data transmission for manufacturers is improved, and the development cost of informationsystem construction is reduced.

Description

technical field [0001] The invention belongs to the field of video network communication, and in particular relates to a video boundary-based data exchange method. Background technique [0002] In the current public security industry, there are generally two types of networks, namely the video private network and the public security network. According to the requirements of the public security system, the data between the private video network and the public security network must use the session initiation protocol (session initiation protocol) for data interaction. Based on the specification of the session initiation protocol, only text and video and audio media streams can be used in the protocol. data to interact. Thus isolating the ability to make service interface calls via other protocols. [0003] The security equipment in "Public Security Information Communication Network Boundary Access Platform Security Specification (Trial)--Video Access Security Part" is used t...

AI Technical Summary

Problems solved by technology

[0004] In actual business applications, there will be various structured data that need to be transferred from the video private network to the public security network for storage, and cannot be quickly developed through remote procedure calls, which increases the development of public security information systems and Docking difficulty, and work costs
