The Application of Decrypting Big-screen Mosaic in Digital Signage System

As we all know, the digital signage system is an emerging industry. Because of its strong association with display terminals, many large-screen splicing manufacturers have entered the signage field. This also made it possible for big screen splicing and digital signage. However, among the people's impressions, large-screen display products are used in monitoring centers, command and dispatch centers, and other fields in most cases. So what's the difference between large-screen display products in digital signage systems and traditional industry applications? Do not worry, the following author will focus on the characteristics of the application of large-screen display products in the digital signage.

Essentially speaking, large screen splicing systems are used as display terminals in digital signage. Unlike other applications, such as monitoring systems, command systems and other applications, the main role is to achieve the display of information, graphics and video. However, since the large-screen splicing system itself is a large-scale, complex-structured, multi-functional integrated system, which coincides with many digital signage systems, a large-screen splicing display system for digital signage is used in actual project operations. During the process, there is still a certain degree of particularity compared with single-screen display.

During the implementation of the project, the project owner will have two different implementation plans for the introduction of a digital signage system with large-screen display products:

First of all, the large-screen splicing display products in the digital signage system, the project will basically design the entire project implementation as an independent display terminal, and will design the splicing display system as a completely independent working system. Of course, its main function is to receive the graphics and video signals transmitted by the superior system (digital signage system), and display on the splicing screen according to the instructions and control of the superior system (digital signage).

Second, the exact opposite of the first completely independent method is to dilute the independence of the large-screen splicing display system. Integrate all parts of the large-screen splicing system into the entire digital signage system for comprehensive consideration. For example, some functions of the large-screen splicing processor are integrated with digital signage propagation and control devices; the large-screen splicing system and the entire digital signage system share a signal transmission, distribution, and scheduling network, including a matrix routing device. Logically, each unit of the large-screen splicing and displaying system is used as an independent digital signage system display terminal, and a function module involving large-screen splicing is directly controlled by the control software in the center of the digital signage system to realize the graphic splicing function.

Of course, neither of these two implementation schemes is good or bad. The system designed by the first embodiment will appear to be very clear in terms of the level of the entire system, and the logic is very clear, which also makes maintenance in the future relatively simple. The second method, because it has played down the independence of the large-screen splicing display system, allows the splicing display system and the digital signage system to be highly integrated, gives full play to the functions of the Hardware and software facilities of various parts of the system, and improves the utilization efficiency of the investment.

However, as the saying goes, everything has its advantages and disadvantages. So, let's look at the disadvantages of these two implementations. The first solution, because the program emphasizes the independence of the large-screen splicing display system, is not conducive to the complementary hardware and software resources between the display terminal and the digital signage system, and will cause unnecessary investment waste.

The second solution is precisely because it has played down the independence of the large-screen display, but because of the large investment in the digital signage system of the large-screen splicing system, or the relatively large number of large-screen splicing systems, the installation position is not independent. On sexual occasions, this also makes the entire system less logically structured than the first one.
