Customer demand
Multiple monitoring signals for large screen system
The public security industry large screen system mainly displays the urban public security monitoring signal. The system needs to have good access to the traditional analog video monitoring signals and the widely used digital monitoring signals.

Centralized display of multiple application systems
With the gradual improvement of public security information construction and the deepening of the integration of three policing, more and more public security application systems need a centralized display platform, which provides decision-making basis for command and scheduling.

High resolution application
The basic background of many majors on the large screen is the high resolution image information of the city, which can not be fully displayed by the ordinary client computer.

Real time display of various graphic and text information
The public security monitoring center has a clear requirement for refreshing speed of various videos, computer pictures and text information on the big screen, and professional system dynamic data refreshing requires real-time.

Countermeasures
In the heart of the public security industry demand characteristics of large screen display control system, and large screen display technology development, our public security launched a large LCD screen system of the leading industry, the public security departments can master the real-time and control of emergency situations and disposal process, realize the efficient and reliable command.

Technical realization
1, comprehensive utilization system of high performance FPGA chip technology, network communication technology, broadband and high performance video encoding technology and a number of high-tech achievements, the various video sources (including traditional analog video signal and the widely used digital monitoring signal compression encoding, etc.) the data can be packaged into Ethernet the transmission of IP stream, the display terminal receives various signal stream and real-time decoding into image display.

2. the system for image acquisition GIS geographic information system, communication system, virtual control command system, digital audio playback system, alarm system, electronic map, leadership system, management system and technology to prevent the subsystem, and then the image is decomposed into network packets through the switch to an output node then, the output node data packet for mixed image, image display at the output.
