How many functions does a multifunctional conference system have? How many functions does a multifunctional conference system have?

Xipai electronic CEO-PA multifunctional conference system generally consists of projection display subsystem, central control subsystem, conference speech subsystem, sound reinforcement subsystem, monitoring subsystem, lighting effect subsystem and network subsystem. All systems are based on computer network, sharing data and control information, decentralized operation and centralized control. So that equipment operators can conveniently and simply monitor all the equipment. With the rapid development of science and technology and society, people have more and more information in their daily lives and work, so information exchange and communication between people becomes more and more frequent and important. Business negotiation, product display, meeting guests, issuing government orders, etc. It's all people-to-people communication. In order to achieve our goal better, we need to use the means we have been using-meetings. Multifunctional conference system is such an automatic conference management system that integrates computer, communication, automatic control, multimedia, image and sound technology. The system organically connects the independent subsystems such as meeting registration, speech, voting, translation, camera, sound, display and network access, and the central controller coordinates the work of each subsystem according to the meeting agenda. Provide the most accurate and timely information and services for various large-scale international conferences, academic reports and remote conferences. Multifunctional conference system uses computer, digital and network technologies to connect all systems, and all signals transmitted on the lines are digitized, which not only greatly improves the sound quality and system reliability, but also fundamentally eliminates the defects of interference, distortion, crosstalk and system instability existing in general conference systems. Let every participant hear a stable and pure voice. The operation of the system and the progress of the meeting are completely controlled, and the operation and installation of the system are very simple.

Features and Composition of Multifunctional Conference System

1. Features of multifunctional conference system

The (1) digital system transmits all digital signals, and the microphones used by the delegates all adopt "analog-to-digital" conversion technology. Most unit devices also use analog-to-digital and digital-to-analog converters, so external analog devices (such as broadcasting, recording, wired or wireless audio devices, etc. ) can directly access the digital system network through the audio media interface.

(2) Modularization For any level of meetings, the matching equipment that meets the requirements can be modularized to form a corresponding system. For the established system, more multimedia devices can be added and controlled by computer software to further expand the system.

2. Composition of multifunctional conference system

Multifunctional conference system can be composed of central control subsystem, multimedia projection display subsystem, voice and simultaneous interpretation subsystem (conference system in general), monitoring and alarm subsystem, network access subsystem and operation and maintenance subsystem. Composition and function of each subsystem unit equipment:

(1) The central control equipment in the central control subsystem is the core of the whole multifunctional conference system. Through it, automatic conference control can be realized, and through computer control, more complicated conference management can be realized. The central control equipment mainly controls voice equipment, simultaneous interpretation, electronic voting, video tracking, digital audio and video channels and data channels.

Its functions are as follows:

1) controls voice equipment, including representative machine, chairman machine, interpreter desk, dual audio interface equipment, multi-function connector, etc.

2) Speaker automatic audio equalization for delegates and chairmen.

3) Manage the microphone, request automatic registration to speak, run the running microphone beyond the authority, and limit the number of participants.

4) Provide conference voting function. When the chairman of the conference initiates a vote on a certain matter, the delegate can control the voice equipment in front of him to vote, which is controlled by the central control equipment, counted and transmitted to the display screen in the hall and the led screen on the delegate/chairman's computer for display.

5) Input and output control of various multimedia audio and video equipment.

(2) Representatives of voice and simultaneous interpretation subsystem participate in the conference through voice equipment. Speech equipment usually includes wired microphone, voting button, LED status display and conference sound, and other equipment can be selected, such as gooseneck conference microphone, wireless collar microphone, LCD status display, language channel selector, representative ID card reader, etc. Simultaneous interpretation equipment mainly includes interpreter's desk, interpreter's earphone and internal communication telephone. The speech and simultaneous interpretation subsystem can realize the functions of listening/speaking request, speaking registration, receiving information displayed on the screen, participating in electronic voting, receiving simultaneous interpretation and talking with other representatives through the internal communication system. According to the identity of the representatives, they have different equipment and power. After applying to attend the meeting, delegates can get the right to listen/watch, but have no right to speak. In particular, the speech equipment used by the chairman of the meeting can control the speech process of other representatives and can choose to allow, refuse or terminate the speech. It also has a microphone priority function, which can temporarily stop the ongoing representative speech.

(3) Multimedia Projection Display Subsystem At present, multifunctional conference display equipment includes TV receiver, LCD screen, LCD projector and DLP digital projector. Through the multimedia display equipment, various digital, text and image materials can be provided to the participants more intuitively, and relevant information during the meeting can also be displayed in real time as required. The signal source can be video tape, computer and DVD player signals from the venue, camera signals or hard disk video recorder signals. These signals are switched and displayed through video distribution of central control equipment.

(4) The monitoring equipment of the monitoring and alarm subsystem includes a camera at the head end, a camera device and a monitor, a hard disk video recorder or a long-time video recorder at the end. It can collect and record the audio and video of the venue. On the one hand, it can monitor the internal situation of the venue for later use. On the other hand, it can send some signals to the translation room to improve the accuracy of translators' translation. The camera should have audio-visual linkage function, which can automatically track the conference microphone being used in the venue and bring the speaker into the picture to meet the needs of live broadcast and simultaneous interpretation.

(5) Network Access Subsystem The network access subsystem is a central control device that connects the main venue and the sub-venue with the general communication network or computer network as the operating environment, and realizes the multipoint digital conference function in local and wide areas to support the electronic whiteboard dialogue and the transmission of voice, data and image files during the conference. Different video network access methods, the technology and transmission speed are also different.

(6) Intelligent, practical, humanized and advanced video tracking subsystem: A. The microphone ID address can be set at will on site, and the attendance unit can be increased or decreased at will to complete the system expansion instantly; B. The intelligent remote controller can quickly set the microphone ID address, quickly adjust and save the preset position of the linkage between the microphone and the camera, and the main control board can also complete the above work. When the microphone is turned on, the camera always tracks the last speaker. When the microphone is turned off, the camera tracks the last speaker. When all microphones are turned off, the camera can shoot any preset target (such as the venue environment or the podium or a specific person). The system supports a single microphone to re-adjust the preset position independently; C. When any preset position deviates from the speaker, the camera can be quickly adjusted through the special remote controller or the system host panel; D. In some occasions where it is necessary to lock the camera to track the target, you can lock the camera with one button by remote control. At this point, any microphone is turned on and the camera is no longer linked to the track. But at this time, the camera is still controlled by the remote controller, and the camera can still be adjusted by switching from 4 to 1 as needed. When the video tracking function is needed, it can be unlocked with one key by remote control (video tracking function is restored);

(7) Operation and Maintenance Subsystem Operation and Maintenance Subsystem provides various user interfaces. (standard PC, LCD touch screen, manual panel, wall panel): At the same time, you can use a variety of operating platforms, personalized control interface design, so that you can operate easily. At the same time, you can see all the conference equipment at a glance.

(8) conference system auxiliary equipment and some auxiliary equipment can also play a matching role in the multimedia conference system. Here are some simple examples.

1) electronic whiteboard: it is as convenient to use as a blackboard, but you can print out what you have written immediately through the printer that comes with the whiteboard.

2) Electric screen: used with projector to obtain high-quality large-format images.

3) On-site lighting: cooperate with the meeting to control the on-site environment.

4) Electric curtains: cooperate with the meeting for on-site environmental control.
