System functional design specification:

In 1, large screen projection:

According to the conference hall of the physical depth and width as well as the scene light condition, combining the human visual habits, according to the room a total area of around 300 square meters, in order to take into account the meeting personnel can watch the big screen on which the video image, the design of the conference room for two pairs of 150 inches of display screen.

This conference room projector and suggested the use of brightness for the 4200ANSI lumen above the NEC high-brightness projector. Resolution of the maximum is 1024 * 768; with 150 inches of snow remote glass bead screen, visual area 2438 * 1828MM, stretching convenient, durable; unique screen brightness high gain, image is clear, bright; fabric fire, mold. Screen using concealed installation. The projector uses lifting hanger mounting means mounting the projector, the projector secure it embodies elegant ( for decoration with good hanger surface treatment ). In order to facilitate the attendees to use laptop presentations as well as various types of information and information query and on demand, on the platform to install desktop information box, with a variety of information interface and a power supply socket. Including AV, VGA, computer audio interfaces. A convenient meeting were multimedia data presentation.

2, sound reinforcement system

300 square meters large conference room, various resolutions and motions and the planning discussion and review of serious meeting environment, realizes the multifunctional conference requirement. Excellent voice quality reduction of the PA system, able to provide clear and natural language sound; the system of simple and fast operation, high intelligent degree. The speaker as a conference room PA speakers, according to the National Conference language sound level design, 4 full range speaker as the main PA speakers, in order to effectively cover the whole audience, set mainly in the lateral proscenium stage above, considering the uniform distribution, selection of speaker six as a supplementary sound, so as to achieve the sound field the smoothness and uniformity. Combining centralized and decentralized approach to the PA, so as to achieve the relevant design index. As a multi-functional conference hall, in the stage play and end the proscenium proscenium setting fixed foldback speakers, to the station broadcasts, return system is to give the chairman's podium speaker and audience between the bridge of mutual understanding, the use of professional stage foldback speakers. The stage sound clearer and more perfect. Set of sound reinforcement system after the United States think digital audio media matrix control and management, its powerful function, internal equilibrium, limit, delay, and with the preset function, according to the conference of the environment, the effect of different settings for different mode, when the meeting opened, only to start set a good program can start the meeting.

3, meeting, video tracking system

Digital conference in delibrate, delegate, large international conference center of digital technology applied to precedent, in which digital technology superiority to develop. With a simple system for processing and transmitting digital signals not only to mate improved sound quality, but also simplifies installation and operation. The control system has two choices: one is to advanced, convenient operation of the software implementation of adjustment and control. Another is the crews to automatic control, convenient operation is their common characteristics. All types of meetings to provide flexible management, whether small informal meetings or multilingual, thousands of major international meetings are handy, operate freely. It is of similar equipment in the first use of digital technology in the system. With multiple functions, high quality, reliable data transmission security. It can be the process of the implementation of comprehensive control. System and video tracking system linkage, achieves high transmission intelligent conference system.

The system can realize the:

Having a discussion meeting function, 1 Chairman, 10 represents;

A FIFO, can set the staff speak quantity, such as 1, 3, 6 or 2, 4, 6

A camera tracking function, when the speech personnel opening speech keys, the camera will automatically track to speak, and the track frame is stored into the hard disk video recorder or sent to the big screen ( the main track on the stage floor staff ).

In 4, the conference system

Conference room main function for daily administrative meetings and staff training, using the 480-540 line of the ordinary camera conference filming, and in the process through the notebook to the projector display conference lectures or training materials, at the same time the signal synchronous recording and broadcast, the conference room live image using CIF / 4CIF codec method, video only need to consume 512K-2M ( according to different video bit rate, bit rate higher image clearer ) network bandwidth, in the usual 2M bandwidth on conference room live remote observation. A convenient meeting management, improving the efficiency, saving manpower, material resources.

4, centralized control

Multi function hall adopts centralized control system, with a 7 inch wireless color touch screen control terminal includes venue all audio, video system switching scenes. Details control include audio and video playback, full function source to stop operation, control interface requirements according to the using habit of preparation, requirements and convenient operation, can choose 8 or 16 control panel to control terminal equipment.

Specific functions for:

1, audio / video and computer signal switching control ( audio and video signal switching, any path of the input signal to the output signal of any road )

In 2, the projection system control ( projector lifting hanger

3, infrared video device control ( DVD machine, MD machine, VOD )

In 4, the relay device control function ( projector, projection screen switch or switch, electric curtain switch ) to realize linkage function, do a " to" click a button can realize the whole pattern of environment (such as: projection mode, the projector end mode), and greatly improving the working effect, the user can focus on monitoring content.
