1. Features
Multiple video inputs—The video processor uses 6 video inputs, including 1 CVBS and 1
SDI (optional), 1 VGA, 1 DVI, 1 HDMI, and 1 USB (1 of 2). The needs of civil and industrial
applications have been basically covered. All video inputs can be switched with fast cut
and fade in and fade out effects.
1 channel audio and video synchronization—1 channel HDMI audio and video, audio and
video synchronization can be achieved when switching videos.
Practical video output interface—The processor has 2 programmable video outputs.
Using 2 DVI output interfaces. These 2 videos are programmed and output to the LED
sending card or display.
Seamless switching of any channel—The video processor The video processor can also
seamlessly switch between any channels. The switching time is adjustable from 0 to 1.5
seconds. Use the fade-in and fade-out switching effect to switch the input channel
smoothly to the second screen. With fast switching, you can switch video output instantly
when switching input channels.
Rich output resolution—The video processor has designed multiple practical output
resolutions for users, the widest of which is 1920 points and the highest of 1280 points,
which is suitable for various dot matrix display screens. Up to 10 kinds of output
resolutions are available for users to choose, and can be adjusted to point-to-point output.
Signal source hot backup—The signal source hot backup can prevent the main screen
input source from causing a black screen on the LED display. When the main channel
input source fails, it will automatically switch to the backup channel input source.
Support one-button black screen-black screen is an indispensable operation during the
performance. When the image output needs to be turned off during the performance, the
black screen key can be used to achieve a fast black screen.
Support picture freeze—During playback, you may need to freeze the current picture to
achieve a "pause" picture. When the picture is frozen, the operator can also change the
current input selection or change the line, etc. to avoid background operations affecting
the performance.
Quickly switch between partial and full screens—The video processor has simple and

http://www.huidu.cn/ 5
practical operations for capturing partial screens and full screens. Any input channel can
independently set different capture effects, and each channel can still switch seamlessly.
The user can arbitrarily set the size and position of the part of the current channel, while
the other channels do not change the method. When switching, some channels or
full-screen functions are implemented between each channel.
Preset recall function—The video processor adopts 10 groups of user presets. Each
group of user presets can store all user settings parameters.
Use the Mode shortcut to quickly recall presets. It can realize parameter backup and fast
on-site call.
30-bit image lossless scaling technology—The video processor uses a dual-core image
processing engine. A single core can handle 30-bit image scaling technology, which can
output from 64 to 2560 pixels, and at the same time can achieve 10 times the image
magnification output, that is, the maximum picture. Up to 25600.
Adopt unique brightness adjustment technology—the built-in brightness adjustment
function of the video processor solves the situation that the gradation is lost after reducing
the brightness, making the color reproduction more realistic.
Set-and-save technology-set-and-save technology solves the user's tedious setting and
manual storage process, that is, the user does not need to implement manual saving
operation after adjusting or adjusting parameters. The video processor automatically
saves user parameters in EEPROM, even if after power-off, the parameters before
power-off remain in the device.
ACC ACM image filtering—The video processor uses the ACC and ACM image filtering
engines. When processing each bit of color, the non-linear filtering effect can minimize the
image loss rate and restore color authenticity.
Support host computer control-you can use the computer's RS232 interface to connect to
the video processor. Use the host computer software to set the output resolution, audio
switching, brightness, switching signal source, etc.
