Problems solved by technology

This is the case that the terminal camera device runs its tasks normally, but when its load is high, conflicts are likely to occur between these concurrently running tasks, and the operation of the signaling task as the core of the system is likely to be affected by other tasks. The operation is affected, which in turn affects the feedback of the terminal camera device to the system command

Abstract

The present invention discloses a method for transmitting information from a client in network video monitoring system to a terminal camera device, wherein the transmitted information is mainly the information for controlling the terminal camera shooting device by the client, such as tilt and zoom lens control information to terminal camera shooting device and control information of image. The adopted mode is transmitting the control information between the client and the terminal camera shooting device with an INFO expansion method of SIP protocol. Therefore, the SIP conversation between the client and the terminal camera shooting device is not affected in the process of control information transmission. Furthermore a signaling channel is adopted for transmitting, and the transmission of medium flow is not affected.

Description

technical field [0001] The invention relates to a method for transmitting information from a client terminal to a terminal camera device in a network video monitoring system, in particular to a method for transmitting control information from a client terminal to a terminal camera device. Background technique [0002] With the development of multimedia technology, multimedia monitoring system is more and more used in security protection, remote monitoring, distance teaching, distance conference, distance presentation, community service and other fields, and plays an important role. At present, real-time monitoring systems through the transmission of video or audio have been implemented in most units and places, such as in some office buildings with corresponding monitoring systems installed, or some living quarters with good safety management systems, or even some private Inside the house, etc. [0003] The terminal camera device is used to collect video streams so that the...
