Video-wall Processor
1. Overview
The Video Wall Processor is a high performance video processing workstation with pure
hardware architecture for spectacular video wall displaying which can be employed in fields
including education and research, government announcement, information publishing,
exhibition and show, controlling and commanding center, security monitoring, etc.
Advanced image processing technologies such as high definition video signal collecting,
real time and high resolution digital image processing ,and advanced three-dimensional
digital filtering are integrated in video-wall processor. Moreover, it also employs largecapacity, high-speed FPGA and CrossPoint switch to ensure the real-time processing of all
input signal and the consistency of the data, leading to no image delay, discretization, frame
loss, which guarantee excellent video displaying.
Video-wall processor is compatible with a wide variety of input signal formats,
including ,CVBS,YPbPr, VGA, DVI, Dual-link DVI, HDMI, SDI, twisted pair signal,
optical signal, etc. The output signal of video-wall processor supports DVI-I, twisted pair
signal, and optical signal. For DVI-I signal, RGB analogue signal and DVI digital signal can
be transmitted concurrently, which means that when video signals displayed on a videowall, it can also be backup and transmitted to another group of displays simultaneously. The
resolution of a single output channel can reaches up to 1920*1200@60Hz. Besides,
customers can also upload and display ultra-high resolution static background images with
video-wall processor. Additionally, ultra-high resolution dynamic background image is also
supported with the extra graphic workstation to achieve perfect displaying.
A series models of video-wall processor are available including 380/580/780/980, which
differ in features and functions, The largest scale of video-wall processor supports the
displays of video wall of 144 screens for maximum. Moreover, video-wall processor also
enables different groups of screens displaying at various resolutions, which is very
significant to the combination of multi-groups of large screens displaying system.
2. Description
Key Features
Cross-screen Displaying
Each signal can be displayed in the cross-screen state, which
means adjacent screens can jointly display the content of a
single signal to form the whole graphics as a “window”.
Customers can also zoom the windows drag them to
everywhere on the screen-wall.
Picture in Picture
A window can be overlaid upon an other windows forming the
“picture in picture”. Moreover, the overlaid window is not
restricted inside the boundary of the underneath one which
offers flexibility to the layout of display.
Four Windows per Screen
Video-Wall processor supports maximum four windows in a single screen allows users to
view more video signals with limited screens. The layout of the windows can be configured
separately which offers flexibility and convenience.
Input Signal Preview
All input signals can be previewed in the UI of software
before being displayed on the screens. It enables the
operator to detect the input status and display signals
correctly.
Other Functions
CrossPoint Switch
Video-Wall processor employs crosspoint switch technology which offers high speed
switching and transmission. Comparing to the “bus” switching architecture that all the
signals need to share the bandwidth of bus for transmission, crosspoint switch assigns each
signal a unique channel to avoid collision,delay, and instability, which contributes to realtime displaying for all video signals.
FPGA architecture
Employing the pure hardware FPGA architecture with self-developed core algorithm
provide Video-Wall processor excellent image processing performance. Abandoning
embedded operation system preventing Video-Wall Processor from crashes, collisions, blue
screen, and viruses which commonly suffered by software architecture. It is highly stable to
ensure uninterrupted operation of 7x24, and meet the increasingly strict demand of market.
Card to Main-board Plugging structure
The main modules including input card,output card, switch card control card, cooling fan,
and power supply are all designed as plugging structure with the main-board which make it
very flexible and convenient for customer to configure the product based on every special
demand. It is unnecessary to disassemble the whole device when replacing the module with
fault. It also supports the ‘hot-plugging’ for input and output cards which means that
customer can plug and pull out the input or output card when the workstation is in process of
working. No restarting of refreshing is needed, and other signals will not be affected.
Resolution Real-Time Total Adaptation (RRTA)
Video-Wall processor employs RRTA( Resolution Real-time Total adaptation) technology
in order to support customised resolutions for different groups of screens, in other words the
resolution for each group of screens can be configured separately in the software which
offers flexibility and convenience for daily application and management .
Graphic Cropping and Signal Upscaling
The graphics of all input video signals can be freely cropped to remove the black edge.
Moreover, customer can zoom in and out any section of the video graphics after cropping.
The upscaling process ensures the zoomed section to be displayed without loss.
Ultra-high Resolution background Image
The built-in storage in Video-Wall Processor allows to store multiple ultra-high resolution
static ‘pixel-to-pixel’ background images which can be uploaded, displayed, and switched
through the software. With extra graphic workstation, the displaying of ultra-high resolution
dynamic background-image can also be achieved to meet specific and professional
requirements.
Character Superimposition
Video-Wall processor supports character superimposition to each input signal channel for
users to identify the signal source. Users can also customise the font, size, position, and
color of the superimposed character.
Scenes Saving, Loading, and Displaying in Loop
Any configuring arrangement of video signal displayed on screen wall can be saved as
“scenes”. Video-Wall processor supports up to 32 scenes to be saved and unlimited scenes
loaded. Customer can also set the scenes to be loaded and displayed in loop.
HDCP-Compliant
HDMI /DVI input card of Video-Wall processor supports HDCP , which enables HDCP
encrypted content to be displayed.
Redundant Power Supply
Video-Wall processor can be configured with dual power supply based on demand. For
circumstances if the power source is not stable, the redundant power supply is highly
suggested to connected to different power source or self-built UPS. In the condition of stable
power source, the device will works on load balancing for each power supply. Once a fault
occurs to the one of the power source, the redundant power supply will start running
automatically to ensure un-interruptible operation.
Controlling and Management
The Video-Wall processor controlling software allows users to manage and control the
processor on PC. It supports Windows2000/XP/Vista/7/8. The Video-Wall processor and
controlling PC can be connected by using CAT5/6 cable(TCP/IP) or RS232 cable. The
software can also control up to 4 extra traditional matrix switchers when they are
cascade(RS232) to the processor.. The Video-Wall processor can also be controlled by
employing the specific controlling keyboard(RS232).
