It is widely used in monitoring, command, dispatching systems, public security, fire, military, meteorological, railway, aviation and other monitoring systems, video conferencing, query systems and other fields, and is deeply favored by users. The digital conference system is a conference system that integrates computer, communication, control, multimedia, image, audio and other technologies into one. It is the development direction of a new generation of advanced conference systems.
Introduction to the Digital Conference System:
  The digital conference system generally consists of a network subsystem, a projection display subsystem, an audio subsystem, a monitoring subsystem, a conference speech subsystem, a lighting effect subsystem, and a central control subsystem. All systems use computer networks as a platform to share data and control information, decentralized operations, and centralized control. It enables the equipment controller to monitor and control all equipment conveniently and quickly.
Today, with the rapid development of science and technology and society, people have more and more information in their daily lives and work. Therefore, information exchange and communication between people has become more and more frequent and more and more important. Business negotiations, product demonstrations, guest meetings, government orders, etc. are all people-to-person exchanges. To achieve better goals, we need to use the means we have always used - meetings.

Digital conferencing system application:
  Digital conference system is such a conference automation management system integrating computer, communication, automatic control, multimedia, image, audio and other technologies. The system organically connects the independent subsystems such as conference report, speech, voting, translation, camera, audio, display, network access, etc., and the central control computer coordinates the work of each subsystem according to the meeting agenda. Provide the most accurate and timely information and services for a variety of large international conferences, academic conferences and teleconferences.
The digital conference system uses computer, digital and network technologies to network the various systems. The digital signals transmitted on the lines are not only greatly improved the sound quality, but also improve the system reliability, and fundamentally eliminate the interference of the general conference system. Defects such as distortion, crosstalk, and system instability. Let every delegate can hear a stable, pure sound. The operation of the system and the process of the conference are fully controlled, and the system operation and installation are also very simple.
Digital conference system features:
(Paperless conference system, ultra-thin one lift) Digital
The internal transmission of the system is a digital signal, and the "analog-to-digital" conversion technology is used in the microphones used by the delegates. Most unit devices also use analog-to-digital and digital-to-analog converters, so external analog devices (such as broadcast, recording, wired or wireless audio devices) can access the digital system network directly through the audio media interface.
Modular
Meetings of any level can be combined to form a corresponding system by modular selection of equipment that meets the requirements. For the established system, more multimedia devices can also be added, and the control is implemented by computer software to further expand the system.
Digital conference system consisting of:
  The digital conference system can be composed of a central control subsystem, a multimedia projection display subsystem, a speech and simultaneous interpretation subsystem (ie, a conference system in a general sense), a monitoring alarm subsystem, and a network access subsystem.
Central Control Subsystem
Central control equipment is at the heart of the entire digital conferencing system. It can realize automatic conference control, and can also realize more complicated conference management through computer manipulation. The central control equipment mainly controls the speaking equipment, simultaneous interpretation, electronic voting, video tracking, digital audio and video channels and data channels. Its function is as follows.
Control of the speaking device, including the representative machine, the chairman machine, the interpreter station, the dual audio interface device, the multi-function connector, and the like.
  Automatic audio equalization of the delegate and chairman's speakers.
  The microphone is managed, the automatic registration of the request is requested, the running of the running microphone is overrun, and the number of participants is limited.
  Provide the voting function of the meeting. When the chairman of the meeting initiates a vote on a certain item, the representative can manipulate the speaking equipment in front of him to vote, and the central control device controls, counts, transmits to the display of the hall and the LED on the representative/chairman's machine. Displayed on the screen.
  Input and output control of various multimedia audio and video equipment.
  Speech and Simultaneous Interpretation Subsystem
Participants participated in the meeting through speaking devices. Speaking equipment usually includes wired microphones, voting buttons, LED status displays and conference audio, and there are other devices to choose from, such as gooseneck conference microphone, wireless lavalier microphone, LCD status display, language channel selector, representative ID card Reader, etc. Simultaneous interpretation equipment mainly includes interpreter desks, interpreter headsets and internal communication telephones.
The speaking and simultaneous interpretation subsystem can realize the listening/speaking request of the meeting, registering the speech, receiving the screen display material, participating in the electronic voting, receiving the simultaneous interpretation and talking with other representatives through the internal communication system. Depending on the identity of the delegates, the equipment they receive and the power they assign are also different. The auditing representative can gain the right to listen/see after joining the meeting by application, but has no right to speak.
In particular, it is important to note that the speaking equipment used by the chairperson of the meeting can control the course of speech of other representatives, with the option of allowing speech, refusing to speak or terminating speech. It also has a microphone priority feature that temporarily silences ongoing delegates.
Multimedia Projection Display Subsystem
Today's multimedia conference display devices include television receivers, liquid crystal displays, LCD liquid crystal projectors, and DLP digital projectors. Through the multimedia display device, various digital, text and image materials can be provided to the participants more intuitively, and related information during the meeting can be displayed in real time as needed. The signal source can be a video tape, a computer and a DVD player signal, or a camera signal or a hard disk recorder signal from the venue. These signals are switched through the video distribution of the central control device for switching output display.
Monitoring the alarm subsystem
Surveillance equipment includes head-end cameras, pickups and tail-end monitors, hard disk recorders or long-term recorders. It can collect and record audio and video on the venue. On the one hand, it can monitor the internal situation of the venue for later use. On the other hand, it can also send some signals to the transliteration room to improve the accuracy of translator translation. The camera should have a sound image linkage function, which can automatically track the conference microphones being used in the venue, and take the speakers into the screen to meet the needs of live broadcast and simultaneous interpretation.
Network Access Subsystem
The network access subsystem uses the common communication network or computer network as the operating environment, and connects the central control equipment of the main venue and the sub-site to realize multi-point digital conference functions in the local and wide-area scope, so that the electronic equipment can be supported during the meeting. Whiteboard dialogue, support for voice, data and image file transfer. The technology and transmission speed of the video network are different. (Paperless conference system, ultra-thin one lift)
There are also some auxiliary devices that can also play a role in digital conferencing. Here are a few simple examples.
Electronic Whiteboard: It's as easy to use as a blackboard, but you can instantly print what you write through the printer that comes with the whiteboard.
  Motorized screen: Use with the projector to get high quality large format images.
  On-site lighting: coordinate with the meeting to carry out on-site environmental control.
  Electric curtains: cooperate with the meeting to carry out on-site environmental regulation.
  Video Tracking Subsystem
Intelligent, practical, user-friendly, advanced microphone-camera linkage tracking function:
The microphone ID address can be set freely on site, and the unit can be added or removed at will, and the system expansion can be completed in an instant;
  The smart remote control quickly sets the microphone ID address and quickly adjusts and saves the microphone-camera linkage preset, and the master panel can also do the above. The camera always tracks the last speaker when the microphone is turned on. When the microphone is turned off, the camera tracks the previous speaker. When all microphones are turned off, the camera can capture any preset target (such as the venue environment or the rostrum or a specific one). Character). The system supports a single microphone to independently re-adjust the preset position;
  When any preset position deviates from the speaker, the camera can be quickly adjusted via a dedicated remote control or system host panel;
  In some occasions where the camera tracking target needs to be locked, the camera can be locked by one button remotely. At this time, any microphone is turned on, and the camera is no longer linked for tracking. However, the camera is still controlled by the remote controller, and can still be performed as needed. Select 1 to switch and adjust the camera; when the video tracking function is required, you can remotely control the key to unlock (recover video tracking function).
  Digital conference system trends:
  The fast pace of work in modern society and the international division of labor have made people less and less able to sit face to face, and the rapid development of modern network technology has brought more convenience to the realization of web conferencing. The digital conference system allows us to “go in” any corner of the world without leaving the house; during the day, we can “keep in” with colleagues and employees from all over the world, and at night we can share family fun with our family; we can attend multiple points at the same time. Meetings and multi-point meetings have made us free from travel and have a job. The sudden SARS virus brought great panic to human society, but also brought the spring of network video communication. Whether it is China Telecom's Xinshitong or China Unicom's Baoshitong, it marks the arrival of a communication "video" era. As a new way of meeting and communicating, the digital conferencing system has unparalleled advantages in other meeting work.
Streaming media technology will increasingly be used in digital conferencing systems. At present, streaming media technology is as popular as the digital conference system, which is an important part of video/audio technology. The integration between the two will open up a broad application space.
  Visual virtual collaboration will be one of the core functions of digital conferencing for enterprises. Most multinational corporations and enterprises with more branches use the digital conference system. In addition to the conference function, the most frequently used ones will be virtual cooperation, such as remote project management, customer service, technical training, etc. Enterprises are particularly obvious.
  Mobile digital conferencing system applications anywhere, anytime will be highly regarded. The terminal devices that most IP digital conference systems can access on the market today are nothing more than PCs and TVs. With the application of wireless access technologies and the popularity of WLANs, mobile digital conference systems will gradually surface.
  The boom in the field of IP digital conferencing has shifted the focus of the market to the low-cost general-user market. From the development of the communication market, we can see that the target market users of most products are gradually shifting from high-end users to low-priced users. Due to the improvement of the technical level, the cost of these products has gradually decreased, and as the application area has expanded, the scale effect has begun to emerge in this field. In this way, the digital conference system will gradually shift from a high-priced dedicated market to a low-priced general user market.
  The digital conference system has changed the traditional conference mode and brought profound changes. It is believed that with the further development and integration of modern communication technology and computer technology, it will penetrate into all areas of social life and play an increasingly important role. Effect.
The digital conference system includes a digital conference discussion system, a digital conference voting system, a conference subtitle system, an IC card sign-in system, and a conference camera tracking system. And the configuration of the complete management software, which can simplify the venue equipment and expand the functions at will, is a set of conference equipment with multiple functions (paperless conference system, ultra-thin integrated lifter).
