Chapter I Overview
LED video processor is a mid-end seamless effects switching video processor market,
which supports digital high-definition input, analog high-definition input, analog SD input,
audio input, enabling all channels of audio and video synchronization seamless
switching.
Listed below LED video processor supports audio and video input format table:
DVI input support VESA standard, highest up to 1920x1200@60Hz
HDMI input 480i/p 676i/p 720p 1080i/p color depth 8/10/12 bit.
VGA input support VESAstandard，highest up to 1920x1200@60Hz
Composite video input PAL、NTSC、PAL-M/N、SECAM
Output format：
DVI output any resolution up to 1920 × 1200 @ 60Hz or 1440 × 1600 @ 60Hz
Custom resolution output.
1. Features
Multi-channel video input - Video processor with 5 video inputs, including 1 CVBS and
1 VGA, 1 DVI, 1 HDMI, 1 USB. Basically already covers the needs of civil and industrial
use. All video input switch and can achieve fast cut and fade switch effect.
Practical video output interface - The processor has 2 programmable video outputs.
With 2 DVI output interface. These two videos are programmed to be output to the LED
sending card or display.
Seamless switching between arbitrary channels - Video processor The video
processor can also be seamlessly switched between any channel, the switching time
from 0 to 1.5 seconds adjustable. Use the fade transition effect, when switching the input
channel, you can make the screen smooth switch to the second screen. Use fast
switching, switching input channels, you can instantly switch the video output.
Rich output resolution - video processor designed for the user a number of practical
output resolution, the most up to 1920 points, up to 1600 points, for a variety of dot matrix
display. Up to 20 kinds of output resolution for the user to choose, and can be adjusted to
the point-to-point output. At the same time, users can also use the custom resolution
output, to meet the various size display.
Support pre-switching technology - Pre-switching technology, is to switch the input
signal, the predicted channel is switched in advance whether there is a signal. This
feature reduces the possibility of direct errors due to line disconnection or no signal input,
resulting in an increase in the success rate of the performance.
Support a key black screen - black screen in the performance process is an essential
operation, during the performance process, you need to turn off the image output, you
can use the black screen to achieve fast black screen.
Support screen freeze - During playback, it may be necessary to freeze the current
screen to achieve "pause" screen. When the screen is frozen, the operator can also
change the current input selection or change the line, etc., to avoid background effects
affect the performance.

Part and full screen fast switching - video processor has a simple and practical part of
the screen capture operation and full-screen operation, any input channel can be set
independently of the different interception, and each channel can still be seamlessly
switched. Users can set the current channel interception part of the screen size and
location, and other channels of the interception of the same way. When switching
between the various channels to achieve part of the screen or screen features to follow.
Preset calling function - The video processor adopts 4 groups of user preset, each
group of user preset can store all the user setting parameters,
Use LOAD shortcuts to quickly recall presets. Can achieve parameter backup and on-site
quick call function.
Unequal splicing and equal splitting - splicing function is an important part of the video
processor, which can achieve equal splitting and unequal splicing, greatly meet the
needs of users in the splicing. In multiple processors to achieve a frame synchronization,
0 delay, no tail and other technology, the show perfect smooth. Unequal splicing and the
screen part of the output for the same setting, the user can read details operating
instructions of the following chapters.
30-bit image lossless scaling technology - video processor with a dual-core image
processing engine, a single core can handle 30-bit image scaling technology can be
achieved from 64 ~ 2560 pixels output, while achieving 10 times the magnification of the
image output, that is, the largest screen Up to 25600.
Using a unique brightness adjustment technology - video processor built-in unique
brightness adjustment function to solve the brightness reduction, the level of loss of the
case, the color reproduction more real.
That is, the existing memory technology - that is, the existing memory technology
solves the user's tedious setup and manual storage process, that is, the user does not
need to manually save the parameters after adjusting or adjusting the parameters, and
the video processor automatically saves the user parameters in the EEPROM even if
After the power is turned 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 to process each color with non-linear filtering to minimize image loss and restore
color realism.
Support PC control - Can use the computer's RS232 interface to connect the video
processor using PC software to set the output resolution, brightness, switching signal
source, etc.
