With the continuous advancement of modern multimedia conferences in various enterprises, a single multimedia technology no longer meets the needs of modernization. The new multimedia conference room integrating multi-function systems has been more widely used in various industries. The times are evolving, and people ’s requirements for the conference system are constantly increasing, and the startup of some equipment during the conference requires manual operation. The frequent switching of various equipment and the cumbersome operation of the equipment make the staff busy, resulting in inefficient conference . Therefore, the modern multimedia conference room more pursues the humanization and intelligence of the multimedia system. The rapid development of multimedia technology makes our need to build a multimedia room with integrated audio, video and conference functions a reality. In addition to considering the traditional meeting requirements, it should also have the characteristics of elegant style and beautiful sound quality, clear image presentation, convenient and fast control, and highly centralized management. The multimedia room conference system is composed of large screen display, multimedia audio and video signal source, audio, switching and central integrated control. A large-screen projector is selected to restore and amplify the VGA and video signals of the DVD and computer and multimedia display platform to images, and restore and amplify the audio through the sound reinforcement system. In order to carry out more efficient and real-time control, it is necessary to equip a set of central integrated control equipment to control all indoor audio-visual equipment, signal switching, lighting, screen lifting, volume adjustment and other functions, which greatly improves work efficiency and simplifies complex operations. Suitable for all people to use without having professional knowledge. 1. System Overview Digital video technology has gradually matured and will quickly change our lives. With the development of Internet broadband technology, digital video technology has been integrated into video conferencing, remote medical treatment, remote education, remote monitoring, streaming media technology, etc. In this respect, and serving all walks of life, for now, digital video technology is undoubtedly a new economic growth point. Second, user needs The entire system should efficiently complete the teaching tasks, combine each system, give full play to the functions of each system, and complete the intelligent video conference. (1) Multimedia display system: The multimedia display system consists of a high-brightness, high-resolution LCD projector and an electric screen; it completes the large-screen display of various graphic information. (2) A / V system: The A / V system is composed of computers, DVDs, VCRs (video recorders), physical exhibition stands, remote video conference systems, power amplifiers, speakers, digital hard disk recorders, and other A / V equipment; Complete the playback of various graphic information (including the use of various software, DVD / CD discs, video tapes, various physical objects, sounds); realize the on-site sound reinforcement and broadcasting of the multi-function hall, with the large-screen projection system, Provide excellent audio-visual effects. And through the digital hard disk recorder, the entire process can be recorded in the hard disk recorder, which is convenient for future inquiry and review. (3) Conference room environment system: The conference room environment system is composed of room lights (including incandescent lamps, fluorescent lamps), curtains and other equipment; complete the change of the entire conference room environment and atmosphere to automatically adapt to current needs; for example, when playing DVDs, the lights will automatically dim, The curtains close automatically. (4) Intelligent multimedia central control system: At present, it adopts the central control system with the highest grade, the most mature technology, the most complete functions and the most versatility in China. This system is currently the most advanced central control system equipment in China. Realize the centralized control of various electronic devices in the multifunctional conference hall. It requires simple operation, humanization and intelligence; The high reliability of the entire system is required; It can realize intelligent control with a high degree of automation, minimize the operation complexity of the operator, and realize the "one-key-in-place" control mode; As much as possible to reflect the excellent functions of various equipment, let all equipment work in the best state, and maximize the effectiveness of the equipment; Can control the projector, perform on / off, input switching and other functions, and can control the electric hanger and screen to realize the functions of ascent, stop, and descent; Can control DVD, video recorder to play, stop, pause and other functions; Can control the physical exhibition stand to zoom in and out; Able to control the volume and adjust the volume; It can realize the automatic switching control function of audio and video signals and VGA signals; Able to control the lights and curtains of the meeting room, automatically adapt to current needs; 3. Principles of configuring multimedia conference rooms There are several principles for configuring a good multimedia conference room: first is the principle of advanced type, second is the principle of practicality, then the principle of scalability and maintainability. The layout of the conference room also has certain skills. In addition to the need for dark lighting for projection, the venue must ensure sufficient lighting. In addition, attention should be paid to ventilation, temperature, and humidity. The temperature of the venue should be maintained at 20-25 degrees Celsius, and the humidity should be maintained at 30-60 degrees. With certain ventilation, people can meet in a comfortable environment.
