Shenzhen Lianchengfa Technology Co., Ltd.

The front-end video multimedia controller equipped with the full-color LED electronic display system adopts the world's leading multimedia image processing technology, which perfectly reflects the multimedia information and further ensures that the full-color display system realizes the use of high-definition digital display terminals.

And its video multimedia controller has the following features:

1. Input first: CVBS, SVideo, YPbPr, HDMI, VGA, YCbCr, SDI/HD-SDI (standard definition/high definition digital video interface), IP, analog RGB (DB15) and digital DVI;

2. Re-output: one of the channels uses single-pixel 24/30-bit or dual-pixel 48/60-bit TTL level, and is transmitted to the LED large screen through optical fiber; the other channel is connected to the monitor through DB15 or DVI; the output resolution meets the requirements from VGA to WUXGA (640×480 to 1600×1200); and supports all ATSC DTV/HDTV modes;

3. The image processing functions include the following:

(1) Motion adaptive progressive processing;

(2) 3:2/2:2 pull-down in movie mode, and correct bad editing in time;

(3) Display mode 4:3 and 16:9 are interchangeable;

(4) Transient improvement of luminance and chrominance;

(5) Programmable brightness and contrast;

(6) Full color processing of chroma and saturation;

(7) Image edge enhancement;

(8) The combination of spatial normalization calibration technology and motion compensation completely realizes smooth zooming of images;

(9) The picture-in-picture technology realizes the superposition of any two input videos;

(10) Picture-in-picture technology is richer in video display mode.

Since the multimedia controller has a complete input interface, it can achieve seamless connection with almost all existing video front-end equipment.
