[Audio Network Information] In today's rapid development of technology and society, people have more and more information in their daily lives and work, so information exchange and communication between people has become more and more frequent. more and more important. Business negotiations, product demonstrations, guest meetings, and government orders are all exchanges between people. To achieve better goals, we need to use the means we have always used.
The digital conference system is a conference automation conference management system integrating computer, communication, automatic control, multimedia, image, audio and other technologies. The system connects the conference report, speech, voting, translation, display, audio, etc. into their respective systems and integrates them organically. The central controller (computer, central control system, etc.) manipulates the subsystems according to the conference situation. 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 make related connections of various systems, and all the signals transmitted on the lines are digital signals. The system implements complete control over the operation of the equipment and the process of the conference, and the system operation and installation are also very simple.
Digital conference system features and composition
(1) Digital signals are transmitted internally by the digital system, and the conference microphones adopt the "analog signal-digital signal" conversion technology. The central host also uses "analog signal - digital signal" and "digital signal - analog signal" converter, so the sound equipment (such as broadcast, recording, wired or wireless audio equipment, etc.) can directly enter through the audio media interface. Digital system network.
(2) The modular central host can meet the requirements of any level of the meeting, the software can select the matching mode to form the corresponding module. For the established system, more multimedia devices can also be added, and the control is implemented by computer software to further expand the system.
2. The digital conference system consists of a central control system, an audio system, a display system, a speech and simultaneous interpretation system (ie, simultaneous interpretation in a general sense), a monitoring system, and the like.
Unit equipment components and functions of each subsystem of digital conference system
1. 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 mode management through computer manipulation. The central control equipment mainly processes, monitors and controls the speaking equipment, simultaneous interpretation, electronic voting, camera tracking, digital audio and video channels and data channels. Its function is as follows:
(1) Control of the speaking equipment, including the representative machine, the chairman machine, the interpreter station, the dual audio interface device, etc. (manipulating the microphone, controlling the microphone switch, operating the microphone that is running, limiting the number of participants, etc.).
(2) Equalize the audio of the delegate and the chairman.
(3) Providing the voting function of the meeting, but when the meeting requests a certain item to vote, the chairman machine can manipulate the speaking equipment in front of him to vote, collect, count and transmit to the display screen of the hall and the representative/chairman's machine through the central control equipment. Displayed on the LED screen.
(4) The ID address of each speaking unit can be set to perform the camera linkage function.
2. Speech equipment and simultaneous interpretation
Speaker devices typically include wired microphones, voting buttons, LED status displays, and conference audio, and other devices are available, such as gooseneck conference microphones, LCD status displays, language channel selectors, and representative card readers. Simultaneous interpretation equipment mainly includes interpreter desks, interpreter headsets and internal communication telephones.
Simultaneous interpretation means that the interpreter uses a special simultaneous interpretation device, sitting in the soundproof simultaneous interpretation room, commonly known as the “boxâ€, while listening to the continuous speech of the source speaker through the headphones, and speaking to the microphone almost simultaneously. All the information content expressed by the person is accurately and completely translated into the target language, and the translated language output is transmitted through the microphone. Participants who need the interpretation service can use the receiving device to adjust to the language channel they need and listen to the corresponding translated language output from the headset.
3. Multimedia projection display system
Multimedia conference display devices include televisions, liquid crystal displays, monitors, projectors, and the like. 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 is generally a video signal, a computer and DVD player signal, a monitoring device signal, a remote signal, and the like.
Note: Introduction to camera linkage tracking function:
1: Use the conference host to set the corresponding ID for all the speaking units.
2: Set the storage position (preset position) of the high-speed dome (camera) and the corresponding speaking unit
3: The central control system uses the power-on feedback code of the speaking unit (the digital speaking unit is powered on with feedback code return) and the corresponding camera storage bit to perform related linkage. You can complete the camera tracking function.
Today, the conference system is widely used, and its functions and quality are quite perfect. The analog era was largely replaced in large conferences. I hope that in the next few years, the digital conference system will be able to bring its own video terminal function, which is much simpler and more convenient.
