LED large screen display system solution:

    LED large screen display system is a set of computer network technology, multimedia video control technologies and ultra-large scale integrated circuit integrated application technology in large-scale integrated electronic information display system,
With multimedia, multi-channel, real-time transmission of high-speed communication data interface and video interface.

The use of computer network technology to make display production, processing, storage and transmission more secure, rapid and reliable. Control system using network technology, networking and computer networks.

Broadcast method:

Video broadcast

     Through the multimedia video control technology and VGA synchronization, you can easily introduce various forms of video information source computer network systems, such as radio and television and satellite television signals, video camera, VCR VCD video signals, computer animation information, etc., which can be to achieve the following functions:

l supports VGA display, display a variety of computer information, graphics, images,

l supports a variety of input methods; supporting PAL, NTSC and other formats

l Real-time display color video images to achieve the live broadcast of

l broadcast radio and television, satellite TV and cable TV signals

l TV, video, DVD and other video signals in real-time playback (VCR, VCD, DVD, LD)

l At the same time playing around with different proportions of the images and text features

 

Computer broadcast

l Graphic effects display function: with pairs of graphic editing, zooming, mobile, animation feature

l shows a variety of computer information, graphics, images, and 2,3-dimensional computer animation and superimposed text

l broadcast system is equipped with multimedia software that can broadcast a variety of information input and flexibility

l There are many Chinese fonts and fonts to choose from, but can also type in English, Spanish, French, German, Greek, Russian, Japanese and many other text

l There are several broadcast methods, such as: single / multi-line translation, single / multi-line up / down, left / right pull up / down, rotate, stepless zooming, etc.

l notice, notices, announcements and news editing, and play real-time release, and there are a variety of fonts to choose from

 

Networking

l equipped with a standard network interface, can be networked with other standard network (information query system, municipal information network systems, etc.).

l broadcast the databases real-time data acquisition, remote network control.

l through the network system can enter the Internet network.

l have a voice interface to access the audio device, to audio and video synchronization

 

Screen Control Machine

Screen control machine to control its corresponding screen display. It can automatically run a continuous loop process, according to the given program to serve to obtain the corresponding single-display data can also be human intervention, resulting in the on-screen display. Pixel on the screen and screen control aircraft displays the corresponding pixel on the region - corresponding to a direct mapping.

On-screen display control machine can manually adjust the brightness, select the gray scale appropriate to the current environment, non-linear calibration data, the screen control machine through the network system can also automatically adjusts screen brightness according to environmental brightness and choose a different gray-scale non-linear correction data.

On-screen image display control machine can adjust the contrast, color and so on. Screen control aircraft will be displayed in the information sent to the video processing and control unit for video processing.

Video processing and control unit

Complete video processing and control unit displays the data image processing, such processing includes:

l second-level gray-scale non-linear correction may be automatic or manual adjustment

l stepless automatic or manual brightness adjustment

l gray-scale control system can control the display to show the color of all 8-bit 24-bit data, namely, 256-color gray.

l Image Noise Reduction: to ensure that the image is more clean and smooth.

l image enhancement, image edge enhancement technology

l motion compensation technology

l hue adjustment function

l visual processing: in the system, you can separately adjust the color brightness of each individual module, adjust the color balance, and basic elimination of mosaic phenomena, all the module and display module brightness uniformity is good, monochrome displays no visual difference.

Video processing and control unit will handle a good display information sent to the communication module to transmit over long distances to the screen.

Communication Module

Communication module to ensure the display screen control machine accuracy in long-distance transmission to the display. Communication module to the transmission of information encoding and decoding processing, for long-distance transmission and reception of data processing. Communication module will display the information sent to the data distribution and scanning units.
