LCD splicing large screen market security companies occupy

In large-scale monitoring or high-end conference projects, the application of LCD splicing technology is inevitable if a large field of view screen is needed. People in the industry all know that when choosing a large-screen splicing program, people who do not know the line first think of choosing the display screen, and those who know the line first choose the splicing processor. Deciding how much water a barrel can hold is the shortest piece of wood. As the core component of the splicing program, the current splicing processor is the shortest piece of wood! It can also be said that the splicing processor is the heart or soul of the large screen splicing system! It determines the display and stitching functions of the large-screen display system!

Over the years, large-screen splicing technology can be divided into two major schools: one based on the IPC board card program, also known as "soft splicing"; one is based on the FPGA array structure embedded program, also known as "hard splicing" .

"Soft stitching" is represented by Emperor Ai Di, Shenzhen. Due to its long application time and computer-based operating system, it has a variety of application functions. Because this program can meet the requirements of our customers' DIY, many businesses can launch their own splicing processors in a short time, so they are sought after by many businesses!

However, as customers continue to improve the mosaic requirements, in addition to window overlay roaming, multi-channel dynamic images, high-definition video have become the basic indicators for customers to build a large video wall.

In this trend, the soft ribs of “soft stitching” gradually emerge: Currently, “soft stitching” on the market cannot display multiple dynamic VGA screens, let alone multi-channel high-definition screens.

Many people believe that the current "soft stitching" technology is difficult to develop, mainly due to the two major bottlenecks in the acquisition bandwidth and processing capacity of the motherboard. As long as these two bottlenecks are solved, the technology will be able to develop rapidly.

Since the "soft stitching" of the IPC mechanism is to collect signals through the PCI channel, and the standard PCI bus bandwidth is 133M, this bandwidth is incapable of acting in the face of multi-path signals or high-definition signals; some companies have taken this bottleneck in order to solve this bottleneck. The graphics signal is compressed and then decompressed for processing, but compression causes the quality of the graphics signal to be severely affected. There are also companies using jumper methods to expand the acquisition bandwidth to around 500M, and even more companies simply abandon the industry's mature and stable PCI bus architecture. In addition to designing motherboard graphics channels to increase bandwidth, some claim to have bandwidth as high as 2G, 4G or even Hundreds of G! Insiders laughed: The development of China's audio and video industry may affect the next generation of computer motherboard architecture, the traditional PCI bus will be eliminated!

Regardless of whether these solutions are mature or not, even if the bandwidth can be reliably and steadily solved, the performance of the processor of the IPC chassis is the same as the performance of the same PC. The motherboard is only a threshold that restricts its performance, as well as the CPU and GPU. And memory, etc., have affected the overall performance of the IPC. So even if the motherboard capture bandwidth problem can be solved, the current CPU and GPU processing power is limited! In the environment where the overall performance of the various components of the computer cannot be greatly improved, the effects of the "soft stitching" program on the market are not satisfactory!

In this context, suppliers of “soft stitching” often flash their words in front of customer inquiries: when customers need high-definition signals, the suppliers often fully accept the promise; but in the end they can only provide high-definition base maps, or can only provide static HD signal or dynamic HD signal!

If a large mosaic wall can not use multiple high-definition dynamic pictures, obviously not a forward-looking splicing system! And the chance of crashing or crashing the soft stitching system is also growing. "Soft stitching" is becoming more and more serious, and the operating system's vulnerability to viruses is also frightening for users!

With the soft ribs of the “soft stitching” technology increasingly prominent, the “hard stitching” represented by Jizhong Science and Technology in China is a sudden emergence. The characteristics of hard stitching make up for the insufficiency of “soft stitching”: stable operation, fast response, and a few Second, it can work, acquisition channel bandwidth is high, support multiple dynamic picture, no operating system, no worry about poisoning and so on.

However, the advantages of the soft stitching application are: Hard stitching is hard to do: For example, soft stitching can provide high resolution base maps in a very respectable manner, support network screen capture, can implement centralized network or decentralized management, and so on. Stitching can't be done temporarily!
