1. Product Introduction
The multi-image mosaic processor is a high-end video processing equipment developed and
manufactured by our company for LED large screen display, performance and leasing, conference
room, studio and so on.
The product adopts CPT+ FST splicing technology targeted for small pixel LED display to
guarantee uniformity and synchronicity of splicing. The Super Resolution Zoom-in Technology
can help eliminate jaggies and reduce the fuzzy sense and out-of-focus phenomenon due to image
magnification.
The product enjoys the following features:
1. Support various signal input includes conventional DVI, VGA, HDMI, CVBS, SDI and IP;
support 4K Ultra HD input and realize large screen point-to-point display.
2. Stand-alone can support user-defined layout of pixel 10.4 million and support output pixels
up to 15360 horizontally or 6144 vertically.
3. Support free-form six-image layout and realize central control of main screen, side screen,
floor tile or canopy of the stage in an easy way.
4. Support signal echoing and view real-time input and output signals by software.
5. Support multi-image preview and output monitoring.
6. Support seamless switch of signal and mode and provide over 10 kinds of transition special
effects.
7. Support overlay of multi-group editable and global image-texts and captions.
8. Support luma key, image transparency adjustment and edge feathering.
9. Support warm backup of multi-level input signal.
10. Support multi-machine synchronous cascade output.

3. Device Debugging
3.1 Device Connection
Device connection could be divided into three parts: power connection, signal connection and
control connection (used for software debugging).
Power connection: device power supply. Connection method: connect power cord to power
plug.
Signal connection: the method transferring signal from signal source to LED large screen.
Connection method: signal source (e.g.: computer)→Mosaic Processor→Transmitting
card→Large screen.
Control connection: connect computer with device control port and debug device connection
method. There are three connection methods
(1) Connect 100MB network control port with splicer LAN1 port, which can set device
software.
(2) Connect computer gigabit network port with splicer LAN2 port, which can not only set
device but also echo signal source image.
(3) Connect one crystal head of serial port line which is randomly donated by device with
splicer COM port, and plug DB9 into computer serial port. Any kind of method among the three
can realize device software control.

3.2 Debugging Steps
Step 1: Click “MENU” to enter into main menu interface and click “Device Mode” to select
splicing mode: copy mode, horizontal mosaic, vertical mosaic and cross mosaic.
Note: Copy mode: all output contents are consistent; horizontal mosaic: content of all output are arranged
horizontally; vertical mosaics: contend of all output are arranged vertically; cross mosaics: contend of all output
are arranged in two rows and two columns.
Step 2: select suitable splicing mode and click “OK”; get back to main menu interface to
select “Screen parameter” and enter into its setting interface. Set loaded screen point of each
output interface and click “Confirm” after inputting, and then screen splice is finished.
Note: there are two ways for number input:
(1) Adjust by rotate knob. Step length can be adjusted by “×1”“×10”“×100”, for instance, “×100”means that
number of rotate knob increases by 100 each time.
(2) Input by number of the front panel. For example, of the key refers to figure 1.
