Brief Introduction to Multi - function Hall System

First, the system overview
    Multi-function hall with its functional diversity (such as: conference hall, video conference hall, lecture hall, academic seminar hall, training hall, etc.), particularly suitable for China's national conditions and needs in recent years, rapid popularization application. In the initial construction investment may be higher than a single function of investment and construction, and from a technical point of view, the system design and construction have some technical complexity, especially for the use of the user side also has certain technical requirements , Which requires a technology to integrate the management of different functions of the A / V equipment to coordinate their work, this technology is the central control technology.
    Second, user needs
    The entire system to complete the remote video tasks efficiently, combined with various systems, give full play to the function of each system to achieve the modernization of the meeting, teaching, training, academic discussion.
    (A) multi-media display system:
    Multimedia display system consists of high brightness, high-resolution LCD projector and electric screen composition; complete a variety of graphic information on the big screen display. As the room size is larger, in order to each location of the people are able to see more clearly, the whole system designed two sets of projector display system.
    (B) A / V system:
    A / V system consists of 2 A / V equipment, such as computer, video camera, DVD, VCR, MD machine, physical booth, mixer, microphone, amplifier, speaker and digital hard disk video recorder. DVD / CD discs, videotapes, all kinds of objects, the sound) playback function; to achieve multi-purpose hall of the live sound, broadcast, with large-screen projection system, with a large screen projection system, Providing excellent audio-visual effects. And through the digital hard disk video recorder, can record the whole process in the hard disk video recorder.
    (C) the room environment system:
    Room environment system by the room lights (incandescent, fluorescent), curtains and other equipment; complete the room environment, the atmosphere changes to automatically adapt to the current needs.
    (D) intelligent multimedia central control system:
    The use of intelligent multimedia central control system, multi-function hall to achieve a variety of electronic equipment, centralized control.
    * Requires simple, user-friendly, intelligent;
    · Requires high reliability throughout the system;
    · Exert as much as possible the outstanding function of all kinds of equipment, let all equipment work in the best condition, play the biggest function of the apparatus
    * To improve the system operator's work, to control DVD, VCR, MD to play, stop, pause and other functions;
    · Can control the projector, on / off, input switching and other functions, and can control the electric hanger, screen, to achieve up, stop, fall and other functions;
    · Can control the camera equipment for left, right, up, down, zoom, zoom and other functions;
    · Ability to control volume, adjust volume level;
    · Ability to control A / V matrix, VGA matrix, realize audio and video, VGA signal automatic switching control function
