Hainan undertake broadcasting, video conferencing systems, video conferencing systems, background music installation.

Hainan undertake broadcasting, video conferencing systems, video conferencing systems, background music installation. Videoconferencing system consists of videoconferencing terminal equipment, multi-point control device, (or audio and video matrix switcher) component. Also includes other equipment as needed, road cameras, image display devices, microphones, editing director of equipment, the venue sound reinforcement equipment, mixers and the like. Wherein the terminal equipment and multi-point video conference control device is a unique part of the system, and the communication line network TV conference system is not unique, it is already present all kinds of communication networks. Equipment videoconferencing system operating in a communication network. End videoconferencing system is actually the beginning of the end, it is the receiving end of information, but also information about the sender, the signal flow is bidirectional. In the end of the video channel, the input device should be cameras, electronic whiteboards (for writing on the blackboard with) Video Showcase (display photos and in-kind) electronic platform, computers. Analog video signal through the A / D conversion. Color signal decoding, format change processing. After feeding source coder coding form compressed video stream, and then sent to the multiplexer, and the audio stream, the auxiliary data, system control information and other composite together to form a composite stream video conference, by the network the interface to the network transmission. Video channel multiplexer output device solvable, video decoders, color encoder / decoder, D / A converters. Audio channel has a microphone, a speaker, A / D converter, D / A converter, audio encoder / decoder and a delay circuit, and other components and circuits. Wherein the delay element is to compensate for video encoding / decoding circuit of the video signal in time-related delay, in order to keep the image and sound synchronization.
