Overview
GTT VGA-D/R HD video codec transmission product is the transmission equipment use LAN to transmit VGA, audio signal. It can adopt point-to-point, one-to-multipoint, cascade transmission mode to transmit VGA signal, digital signal, and stereo audio signal.
The equipment digitize the HD audio/video signal to TS stream and transmit through network, the transmission cable is super five-type-line. One encoder can take hundreds of decoder. Through this transmission mode, it can use one network cable to transmit HD audio/video signal of all LCD screen of an advertising area. And can adapt several kinds of network connecting mode, the middle part can adopt switch etc network equipment to extend transmission distance. When adopt optical network, the transmission distance can up to several dozens of kilometers. The video interface is VGA, can transmit digital HD video signal.
The video input of encoder is VGA interface + audio interface, the image resolution does not need to setting, can automatic recognition according the output resolution of display card. The image is high definition, can directly input 720P HD video, and is undistorted, high capacity of anti-interference and stability.
Audio signal adopt digital codec transmission mode, has stereo audio output, after the encoder use linear PCM to digitize audio signal, the code rate is about 700Kbit/s. One route stereo signal code rate can up to 1411.2Kbit/s. Adopt compressed encoding technology to compressing. The transmission system is convenient to install, no need to debug and IP address setting, plug and play, no need software support, the monitor can be projector, TFT-LCD TV、PDP.
