On characteristics and development trend of digital conference system
December 8th, 2011 | share | No Comments »
In the rapid development of technology and society of today, people in daily life occupies a growing amount of information and contacts and work, information exchange and communication between people are becoming more frequent, more and more important. Business negotiations, presentations, guest interview, decrees issued, and so on are the exchanges between people, to better fulfill the purpose you have to use the means we use consistent——meeting.
Digital conference system is a set of computer, communications, automation, multimedia, images, audio technology, which integrates business automation management system. System will report to the Conference, to speak, vote, video, sound, display, network access separate subsystems organically synthesizes a body connected, coordinated by the central control computer based on the agenda of each subsystem works. For Nikon Coolpix S70 Battery Charger various major international meetings, academic report meeting and teleconferencing provides the most accurate, real-time information and services.
Digital conference system is today’s most advanced conference system, it is the use of computer system network, digital and network technologies, digital signal transmission lines, not only greatly improved sound quality, increased system reliability, but also fundamentally eliminate the General Conference system interference, distortions, defects such as crosstalk and system instability. So that each delegates were able to pick up stable, pure sound. System operation and meeting the process of implementation of a comprehensive control and system operation and installation is very simple.
Digital conferencing system characteristics and composition
1. Characteristics of digital conference system
(1) digital
Transfers within the system are all digital signals, participants used microphones have been used in “mode-number” conversion technology. Most of the unit also uses a die-and array-mode converters, so external analog devices (such as broadcast, recording, audio equipment, wired or wireless) through audio media network interface directly into the digital system.
(2) modular
Meeting demands on any level, you can choose to meet the requirements through modular device combination to form the corresponding system. To the established system, or you can add more multimedia devices through software control, allowing the system to further expansion.
2. Digital conference system
Digital conference system, multimedia projection displays can be controlled by the Central subsystems subsystem, to speak and simultaneous interpretation system (that is, the general sense of the Conference system), monitoring, alarm subsystems, and network access subsystem components.
Second, the digital conference system unit composed of subsystems and features
1. Central control subsystem
Central control device is the core of digital conference system as a whole. Conference on automatic control can be achieved through it, or by computer manipulation to achieve a more complex session management. Central control equipment mainly speak on equipment, simultaneous translation, electronic voting, digital audio and Panasonic Lumix DMC-FP8 Battery Charger video control channel and data channel. Its function is as follows.
(1) control to speech devices, including representative, President, the interpreter console, dual audio interface, multifunctional connectors, and so on.
(2) the representatives and the President of the speaker are automatically balanced audio processing.
(3) manage the microphone, asked for the floor automatic registration, is running run microphones ultra vires, limit attendance, and so on.
(4) providing Conference voting, when the President of the General Assembly, when you vote on a particular issue, on behalf of steerable device to vote in front of him, from the central control device control, statistics, transport to a display Hall and Representative/Chairman LED displays on the screen on my computer.
(5) various multimedia audio and video equipment of input and output control.
2. Speak and simultaneous interpretation subsystem
Participants speak by equipment involved. Speech devices typically include wired microphone, voting buttons, LED status display and Conference sound, and other devices are available to choose from, such as the goose neck Conference microphone, wireless led channel-clip microphone, LCD monitor, language selector, on behalf of chip-card reader, etc. Simultaneous interpretation equipment main interpreter, translator headphones and internal communication telephone.
Speak and simultaneous interpretation system enables listening/speaking request, statement of Conference registration, receiving screen displays information and participate in the electronic voting, receiving simultaneous interpretation and through an internal communications system to speak with other representatives, and other functions. According to the identity of the participants are different, they received equipment and assigned to the power is correspondingly different. Observing after application to join the meeting, the representative can gain powers to listening to/watching, without the right to speak.
The special is to be noted that, the President of the Conference statement used by the device, you can control other statements by the representatives of, you can choose to allow statement, refused to speak or termination to speak. It also has a microphone priority feature enables ongoing temporary static statements by the representatives.
3. Multimedia projection display system
Now multimedia for display devices including TV, LCD, LCD LCD projectors and DLP digital projector, and so on. Through multimedia display device can be more intuitive to provide participants with different numbers, such as text and image data, also displayed as needed in real time during a meeting of Panasonic DMW-BCG10PP Battery Charger relevant information. Signal source can be a video signal, computers and DVD players, can also come from the venue of the signal or DVR camera signals. These signals through a central control device for video distribution, switching output display.
4. Monitoring alarm subsystem
Monitoring equipment, including head-end camera, pick-up device and at the end of the monitor, hard disk video recorder or video recorder for a long time. It can be the venue for collection and recording of audio, video, and can monitor the inner workings of the venue for later use on the one hand, on the other hand can also took some signal to the transliteration in order to improve the accuracy of translators translate. Cameras should have sound and linkage function, you can automatically track venue meeting microphone that is being used, speaker intake screens, meet the needs of live telecast and simultaneous interpretation.
5. Network access subsystem
Network access subsystem is the use of common communication network, or computer network for running environment, central control device attached main venue and breakout, achieving local and wide-area multipoint digital conferencing features in the range, which can be supported during the meeting Whiteboard dialog, support voice, data and image files transfer. Video network access in different ways, the technology and transfer speed is not the same.
There are also auxiliary equipment is also able to play a coordination role in digital Conference, here are a few simple examples.
(1) electronic whiteboard: use as easy as like a Blackboard, but instantly through the Whiteboard’s content written by the printer printed out.
(2) electric screen: used with the projector, so that access to high quality large format images.
(3) lighting: facilitate on-site environmental control meeting.
(4) electric curtains: facilitate on-site environmental control meeting.
Third, the development trend of digital conference system
The fast pace of modern social work and international division of labor, so that fewer and fewer people can sit together face to face meeting, and the rapid development of modern network technologies, but also for the realization of Web conferencing to bring more convenience.
(5) various multimedia audio and video equipment of input and output control.

Observing after application to join the meeting, the representative can gain powers to listening to/watching, without the right to speak.
The special is to be noted that, the President of JVC BN-VF808U Battery Charger the Conference statement used by the device, you can control other statements by the representatives of, you can choose to allow statement, refused to speak or termination to speak. It also has a microphone priority feature enables ongoing temporary static statements by the representatives.
