Embodiment Construction

[0031] At first, explain the key of the present invention:

[0032] (1) Content definition of control protocol message header field:

[0033] Start flag field: 2 bytes in length, the start flag of the control protocol message header. After receiving the control message, the receiving end first judges whether the start flag of the message is consistent with the definition. If not, the control message is considered to be wrong , discarded directly.

[0034] Version information field: 2 bytes in length, controlling the definition of the protocol version, which is convenient for compatibility with the old protocol after the protocol is upgraded in the future

[0035] Message type field: 2 bytes in length, indicating the content format of the control message.

[0036] Message length field: 2 bytes in length, including the total length of the message header and message body (XML content). The receiving end uses this field to deal with the subpacket and sticky packet phenomenon du...

Abstract

The invention relates to a control protocol and a corresponding remote video monitoring system, wherein, the control protocol uses a TCP way for transmission in an IP network, and controls the protocol content to adopt an XML pattern; the remote video monitoring system consists of a monitoring front-end (1), a signaling cut-in server(21), a central server (22), a medium cut-in server, a monitoring client end (3), and an IP network, and the control protocol is adopted in the monitoring of the front-end register and the information signaling transmission. The information transmission of the control protocol is instantaneous, and is realized simply and is convenient to be extended, the corresponding remote video monitoring system has the advantages that the signaling-control information response speed is rapid, at the same time, the networking is convenient, the extending is easy, and the load sharing is achieved, thereby increasing the system function.

Description

technical field [0001] The invention relates to computer network and multimedia communication, in particular to a control protocol and a corresponding remote video monitoring system. Background technique [0002] The development of video surveillance system has gone through three development stages of analog, digital and network video surveillance, its application is more extensive, and the scale of the system is constantly expanding, especially the role in social public security is more obvious and prominent. However, due to the lack of a unified industry standard, there is no unified standard for the signaling control protocol in the video surveillance system, the market is relatively chaotic, each company operates in its own way, the products are not compatible with each other, and there is no open interface design, the product is reliable Performance, stability, scalability, etc. cannot meet the needs of various users. [0003] In addition, the Chinese invention patent ...
