What should be paid attention to in the selection of the monitoring matrix? The selection of the monitoring matrix for broadcasting and video conferencing applications should use broadcast-grade products, monitoring applications can use monitoring products, and video signals should use monitoring signal matrix. The specific details are as follows:
Matrix interface selection
With the development of image signal technology, humans have improved the audio and video vision, and the transmission of image signals has also undergone several stages of development, from AV video to color difference component (YPbPr) to VGA signal, now to DVI and HDMI. The corresponding matrix switcher appears in each signal phase; the diversity of matrix switchers, naturally we will see a variety of different types of interfaces; different types of interfaces are also different in function and use. Take video signals as an example. Common interface types are: D-15 type interface, BNC interface, RCA (Lotus head) interface, DVI interface, S-VIDEO interface, RJ45 interface, and so on. In engineering applications, specific device interface forms are selected based on the format of the switching signal and the actual transmission needs. For example: computer video signal selection D-15 type interface, industrial and military video signals to choose BNC interface, home entertainment and civilian video equipment with lotus interface, computer digital video with DVI interface, network digital video with RJ45 interface, HDMI with digital HD Dedicated interface, and more. The interface selection should be accurate. Try not to use the adapter to convert the interface form, causing unnecessary signal loss and affecting the quality of the project.
Matrix bandwidth selection
The so-called bandwidth is the abbreviation of the passband width of the display video amplifier. Every electronic circuit has an inherent passband. The wider the bandwidth, the faster the response, the higher the frequency of the signal that is allowed to pass, and the smaller the signal distortion.
Different signals have different bandwidths, audio signal bandwidth is lower, video signal bandwidth is higher than audio, and VGA signal bandwidth is higher than video signal. The current high-definition video signal has a very high bandwidth, so in the bandwidth selection of the matrix product, it is strongly recommended to purchase a high-bandwidth HD video matrix.
The computer's VGA signal, the higher the resolution, the shorter the signal transmission distance, and the higher the bandwidth of the matrix. Bandwidth is a problem that needs to be carefully considered when selecting a matrix switcher. In order to clearly transmit image signals, in order to expand the high-definition image device in the future, it is necessary to select a high-bandwidth HD video matrix matrix.
Matrix compatibility selection
Compatibility refers to the degree of coordination between hardware, software, or a combination of hardware and software. For software compatibility, it means that a certain software can work stably in several operating systems without unexpected exits. Matrix is ​​the core device in audio and video engineering, from various sources of different devices, which requires the matrix to have higher compatibility. This makes the matrix have a higher input amplitude range at the input end, the output end must have a certain driving capability, and the impedance matching between the devices is appropriate.
HT-DMX is a high performance HD video matrix switching system. Support VGA, DVI, YPbPr, CVBS, HDMI, SDI, fiber LC, H.264, twisted pair HDBaseT and other formats mixed; bandwidth 4.25Gdps, support H.264 TS video stream output and support network remote control; good compatibility The mean time between failures (MTBF) is 30,000 hours. The system integrates high-definition video signal switching control, video format conversion, transmission, large-screen splicing display and network remote management, which not only realizes analog signal, high-definition conversion, display and routing of digital signals, but also can be used for video. The signal is compensated, corrected, driven, etc. It can realize remote software upgrade, remote control, and quick control through keyboard. Mainly used in various industries visual command center, TV station, advanced conference room, monitoring room, etc. It provides a unique solution for professional engineering that requires high-definition digital audio and video switching, management, and control.

Polyester Polyol For Adhesive

China Polymeric Polyol Material,Polyester Polyol For Adhesive manufacturer, choose the high quality Liquid Polyester Polyol,Raw Polyurethane Resins, etc.

Polyester polyol is a type of polyol that is derived from the reaction between a polyol (such as glycerol or ethylene glycol) and a dicarboxylic acid (such as adipic acid or phthalic anhydride). It is commonly used as a raw material in the production of polyurethane foams, coatings, adhesives, and elastomers.


Polyester polyols have several advantages over other types of polyols. They have good chemical resistance, mechanical properties, and thermal stability. They also have low toxicity and are environmentally friendly. Additionally, polyester polyols can be easily modified to achieve desired properties, such as increased flexibility or flame retardancy.


Polyester polyols are typically liquid at room temperature and have a high molecular weight. They can be further reacted with isocyanates to form polyurethane materials, which have a wide range of applications in various industries, including automotive, construction, and furniture.
