Introduction of Software Edge Blender and Hardware Edge Blender

Software edge blender

The software edge processor is not as effective as DLP when it is used to integrate low-end projectors such as LCD devices. But it still has many shortcomings.

Software edge blender is generally based on the combination of the computer (including the operating system) + signal acquisition card (VGA signal, composite video signal) + splicing card (display card output to the projection display device).

1. When multi-signal acquisition is applied and simultaneous display is required: the computer processing capacity is limited, and there will be a delay in picture playback. The main problem occurs in the bus occupation between the computer and the signal acquisition card.

2. Crash: Needless to say, the computer will crash once or twice, mainly depending on whether the application is critical. If the leader is talking, the video broadcast suddenly jams, and such an emergency cannot be handled.

3. It is easy to get virus: win operating system is the object of all hacker attacks. If you don’t keep track of which Trojan program will cause the system to be paralyzed, unless you are not connected to the Internet, you don’t need a U disk to copy video files on the fusion machine.

4. Motherboards and accessories: These accessories can be found in the computer markets all over the country. The real civilian products are not a bit worse than the industrial grade. Many problems will be discovered after a long time.

5. Cannot run high resolution

6. Unstable and prone to various problems. After-sales is more troublesome and requires technicians to debug frequently.

In addition, there are many integration problems, slow computer operation, etc.

Hardware edge blender

The true pure hardware fusion device is developed based on the single-chip technology. Its geometry correction, fusion correction, signal input and output processing and control are all undertaken by their respective boards, regardless of the number of signals, quality and stability of the equipment, and the software compared with the device, it has an absolute advantage.

The solution based on PC architecture and hardware fusion card has certain advantages in specific applications, but there are also various limitations and unstable factors brought by the open operating system.

Pure hardware edge blending processor products occupy a dominant position in most industry applications due to its ultra-stability and outstanding acquisition and input performance. The outstanding features are as follows:

1. Pure hardware FPGA architecture, no Windows operating system, no crash.

2. Its own bus and data exchange technology breaks the bandwidth bottleneck, and in principle the input and output scale are unlimited.

3. Input board automatic identification function, the input and output board cooling module can be hot swapped

4. Large-scale collection of various input signals. VGA / HDMI / DVI / HD-SDI / YPbPr / DVI Dual-Link high score / high image quality CVBS / standard image quality CVBS, its flexibility and convenience are extremely strong.

5. The application of high-resolution acquisition card completely solves the bottleneck of large-resolution signal acquisition and display. 
The single port 3840 * 2400 true 60HZ high specifications meet the demanding collection requirements.

6. Perfect compatibility and controllability, easy to combine with other application systems. Both the network and the serial port can be easily controlled.

7. Super stability and reliability. Power supply redundancy, 24 * 365 uninterrupted operation.
