The emergence of high-definition mixing matrices in recent years has changed the situation where different signals require different signal matrix switching in the past, and the signal receiving terminal must have a corresponding signal format interface; the HD mixing matrix can receive any analog signal in any resolution and format. And digital signals, some can also receive long-distance transmission of RJ45 or optical fiber any format signal, and the output can be a unified high-definition signal format signal, and some can also output long-distance transmission RJ45 or optical fiber unified format clear signal. High-definition mixing matrix appears to be the popularization stage of high-definition signals, just to solve the over-popular phase of high-definition signals, a large number of various resolutions, various types of analog signals and digital signals unified switching problem.
Once the high-definition mixing matrix emerged, it was rapidly applied to various AV projects of various signal sources such as command centers, dispatch centers, analysis centers, conference centers, video conferences, virtual simulation centers, and image displays. It is estimated that over 85% of newly-built command centers, dispatch centers, analysis centers, and high-grade conference centers use signal switching equipment that is a high-definition hybrid matrix, which greatly replaces the traditional signal switching matrix. High-definition mixing matrix has been applied to various engineering projects and has been accepted by more and more users.
JS-S-MIX series high-definition hybrid matrix switcher is a high-definition hybrid matrix introduced by Beijing Golden Vision Tianchuang Technology Co., Ltd. This series of high-definition hybrid matrix is ​​suitable for input and output exchange of video signal and audio signal number in various formats. Your actual needs, choose the most suitable audio and video input, output card, to avoid the use of too many audio and video converters to save system costs, reduce the accident rate of the signal, reduce the attenuation of the signal due to excessive conversion, to achieve the image High-fidelity signal output.

Provides a unique solution for high-definition digital audio and video switching systems.
Second, industry applications
2.1 Monitoring Command Center Application In the monitoring command center system, the JS-S-MIX series of high-definition hybrid matrix is ​​a pure hardware architecture, which is stable and reliable, and meets the needs of 7*24 hours of operation of the monitoring command center. With the development of science and technology, there are more types of system equipment, more and more powerful performance, and higher system complexity. Digitization, networking, and scale are the ideal performance qualities of current monitoring systems.
JS-S-MIX series high-definition mixing matrix is ​​a modular design, and can be configured with a variety of format module boards, including traditional CVBS, VGA analog signals, and digital high-definition DVI, HDMI, YPbPr, SDI and other signals. It eliminates the conversion equipment between various signals, simplifies the system, reduces conversion links and failure points, and improves system stability.
JS-S-MIX series high-definition mixing matrix can directly decode the remote network camera signal, and can also integrate PTZ control into JS-S-MIX system software to achieve unified control.
2.2 Multi-function Conference Room Application In the multi-functional conference room, there are high requirements on the signal quality. The JS-S-MIX series HD mixing matrix is ​​a separate processing module for each channel, and the internal is a digital 1080P processing channel. Its signal switching speed, but also has a seamless switching function. Multiple input and multiple output signals can be switched independently or in groups. In the conference system, the display end of the signal includes a display, a projector, a hard disk recorder, a large screen display, and the like. Each output of MAX can be matched with the display resolution to achieve the best display effect.
JS-S-MIX series HD mixing matrix multi-functional conference room provides a one-stop solution for signal acquisition, processing, switching and transmission in multiple formats.
Third, the system topology
Fourth, equipment characteristics
4.1 seamless switching JS-S-MIX Series HD mixed matrix signal to achieve a completely seamless switch, in real sense to achieve "0" seconds switch, the end is not a black screen, no blue screen, no splash screen.
4.2 Custom Output Resolution The JS-S-MIX Series HD Mix Matrix devices can configure the same or different resolution for each output channel. In this way, in the project, it can adapt to different resolutions supported by different models and different groups of monitors. Compared to a matrix with only one resolution available on the market, the MAX series offers higher application flexibility and provides a perfect solution for projects with diverse resolution requirements.
4.3 Associated Audio The JS-S-MIX series of high-definition hybrid matrix devices support simultaneous switching of single-channel, multi-channel audio and video signals, and single-channel, multi-channel audio/video switching.
4.4 Supporting Splicing Functions In conjunction with functional output boards, a single signal can be displayed across multiple screens, enabling multiple screen splicing displays for key signals. The size and position of the signal window can be adjusted arbitrarily.
4.5 Character Overlay Function Supports the character superposition function of the input signal, which can superimpose characters on all input channels to facilitate the customer to know the source of the displayed signal in real time.
4.6 Status Display Function Supports working status indicator indication, automatic detection of no signal input "nosignal" state prompt, the user can quickly grasp the current working status of the equipment according to the status indicator of the machine.
4.7 Diversification of Control Modes The JS-S-MIX Series HD Hybrid Matrix supports TCP/IP network or RS232 port for control. The hybrid matrix is ​​connected to the switch of the existing network. Users can realize independent management and collaborative management of multiple matrixes through the network workstation, and can also perform cascading control through the serial port. Hybrid matrix open control protocol that supports third-party devices to control it. For example, in the field of security, support for control through the security dedicated keyboard, complete the signal switching on the screen, the key signal amplification and other conventional operations.
4.8 Redundant Power Supply Design The system adopts multiple redundant power supply modes to share the load. When a certain power supply of the system fails, the system automatically switches to standby power supply to ensure the uninterrupted operation of the equipment. At the same time, the system has automatic monitoring. Function, convenient for users to check the working status of the equipment;
4.9 Modular Design, Supporting Hot Swap The whole system adopts a modular design, including input cards, output cards, switch cards, control cards, fans, power supplies, etc., and supports hot-plugging. The modular design brings great convenience for daily use and maintenance. When the system fails, the faulty module can be replaced on site without having to open the chassis, and the normal operation of the system can be quickly restored. The hot swapping features of the input module and the output module enable the system to replace and upgrade the input and output modules without interruption, without affecting the normal operation of the system and ensuring the stability, flexibility, and reliability of the system.
