LED outdoor display network control system
It is by the control computer, display control system, multi-media
display systems, editing, playback software, etc..
Under normal circumstances, the user only using a stand-alone
computer-controlled electronic display, this time, as long as
installed on your computer sync grayscale controller, multimedia
video graphics card, sound card, etc., you can play through the
editing software control display system the normal work.
However, in order to adapt to future development, product
development provider of open display control system uses a computer
network technology, able to many of today's sophisticated digital
technology into the large screen display system, such as database
technology, network communication technology, network interconnect
technology information automation technology, interface technology, multimedia
technology.
Networking technology and the future of the network systems
connected, including the user's Intranet and Internet
interconnection networks, etc. can also be information on the
various other systems required format for real-time display to the
big screen.
Through the multimedia video control technology, can easily
introduce various forms of video information source computer
control system, such as radio and television and satellite
television signals, video cameras, video signal, VCR, DVD video,
computer animation information, video surveillance information.
To sum up, you can achieve the following functions:
⊙ real-time display on a computer screen color RGB or video images
⊙ when necessary to achieve the live broadcast and cable television
and satellite television broadcast
⊙ camera, VCR, LD machines, VCD machines, DVD video playback etc.
⊙ can be on TV screen and produce their own programs in the
superimposed text information, for special effects, real-time
editing and playback Product providers in the electronic display system, computer and
network control system based solely on the user's actual
applications. Take full account of the user's application environment, both human
and personalization. See the following user multimedia outdoor electronic display system
architecture diagram briefly that part of the application.
1. Web server
Web servers are the internal network (Intranet) data and
documentation center, but also a variety of LED screen display
system information and data sources, it is to other workstations on
the network to provide file services and data sharing services. Workstations, and the exchange of data between workstations is
achieved through the server. 2. Display control computer (network workstation Workstation)
Display control computer to control the screen display. It can automatically run a continuous loop process, according to
the given program to a single server or their own local hard disk
to obtain the corresponding display data can also be human
intervention, resulting in the on-screen display. Pixel on the screen and control the computer display corresponding
pixel on the region-one correspondence, direct mapping.
System operators can control the display through the system control
machine power switch, and display real-time monitoring of various
failures occur, such as overvoltage, undervoltage, overcurrent,
leakage, temperature and humidity changes, fire, smoke and so on. 3. Multimedia Video Display System
Control the media inside the computer to install a video card, the
video card to synchronize the composite video signal separation,
chroma signal separation, color decoding, for red / green / blue
signals A / D conversion, the A / D converted digital Si |
