1. Introduction

BV4000 Video Wall processor is a new high-performance video image processing  workstation with pure hardware architecture and free of operating, which can display  multiple dynamic images on multiple screens and realize the function of multi-window  splicing. The processing mechanism of large capacity, high-speed FPGA and  CrossPoint switch, ensure real-time processing of all input signals and data  consistency. At the same time, it has high stability and fast start-up speed and supports  365 x 24 hours of uninterrupted and stable operation. 

BV4000 Video Wall processor is available in 3U and 5U models. The card is  designed with card-in-card structure and can be flexibly configured according to  requirements. It support the splicing display of 32 large screens. Support DVI signal,  HD signal format input and output, compatible with various common resolutions, and  can realize custom unconventional resolution, with a single output resolution of 1920  x 1200 @ 60Hz. It is suitable for education and scientific research, government  announcements, information publishing, administration, conference center, exhibition  and display, security monitoring, home appliance sales and other industries.

2. Feature

Seamless handover — A huge amount of data transmission chip technology dynamically sets up point-to-point dedicated data channels for each signal, each signal  has its own dedicated channel for transmission. The video switching interval is less  than one frame, which is imperceptible to human eyes and realizes seamless switching  of signals. 

EDID editing — Support reading, modification and customization of EDID,  greatly improving the compatibility of large-screen display devices. It can support some  special resolutions by importing EDID information, adapt to various conventional and unconventional applications. 

Character Superimposition — It supports character superposition settings for  each signal source, supports modify the position, font size, font color and background  color of characters. 

Signal source clipping — It supports the functions of edge removal and clipping  for all signals, making the control methods of the picture richer more diverse,  perfectly solve the black edge problem of the front-end signals. At the same time, it also support realize local amplification through the clipping function, helping users to  efficiently view important areas in the image.

Scene Save and Read — Any configuring arrangement of video signal displayed  on screen wall can be saved as “scenes”. Video Wall processor supports up to 40 scenes to be saved and unlimited scenes loaded. Customer can also set the scenes  to be loaded and displayed in loop. 

Controlling and Management — The Video Wall processor controlling software  uses the standard TCP / IP protocol when communicating and managing with devices  using network ports. It not only manage devices in local area networks, but also  manage online devices in remote networks through IP networking.

Screen split display — Support the function of screen division and display, and  each output channel can perform multi-screen division and display. 

Picture roaming — Each window can roam freely in the output screen and can  be displayed on any one or more large screens. There is no boundary limit on the area  of the screen display.

Picture scaling — The picture size of each window can be scaled arbitrarily, there is no specific size limit for the reduction or enlargement of the picture, the whole  field of view of the picture can be filled up at the maximum when the picture is enlarged. 

Picture overlay — The hierarchical relationship and layout position of each picture  can be customized arbitrarily, without being constrained by the size of the image space,  the upper and lower levels of each picture can be adjusted arbitrarily

Picture abnormality correction — The abnormal image deviation caused by  various reasons can be corrected, so that the offset image is normally displayed on the large screen, and the image correction of the abnormal image can be easily realized. 

Frequency doubling line —It supports the function of frequency doubling and  line doubling, the processor can automatically perform line doubling processing  according to the window size of the image, it can perform frequency doubling and  enhanced display on the input signal source with low frame rate, realize perfect  enhancement echo of low resolution and low frame rate signals.
