Today, with the rapid development of science and technology and society, people have more and more information in their daily life and work. Therefore, information exchange and communication between people become more and more frequent and important. Business negotiation, product demonstration, guest meeting, decree issuance and so on are all exchanges among people. To better achieve the goal, we need to use the means we have always used - meetings.
Digital conference system is an automatic conference management system which integrates computer, communication, automatic control, multimedia, image, audio and other technologies. The system integrates conference report, speech, voting, translation, display and audio into their respective systems. The central controller (computer, central control system, etc.) controls the work of each subsystem according to the meeting situation. It provides the most accurate and timely information and services for various large-scale international conferences, academic conferences and teleconferencing.
The digital conference system is connected by computer, digital and network technology. All the signals transmitted on the line are digital signals. The system controls the operation of equipment and the process of meeting comprehensively, and the operation and installation of the system are very simple.
1. Characteristic and composition of digital conference system
The internal transmission of the system is digital signal, and the conference microphone adopts the technology of "analog signal-digital signal" conversion. The converters of "analog signal-digital signal" and "digital signal-analog signal" are also used in the central mainframe. Therefore, audio equipment (such as broadcasting, recording, wired or wireless audio equipment, etc.) can directly enter the digital system network through the audio media interface.
Meetings at any level required by the central host can be assembled into corresponding modules through software selection of matching modes that meet the requirements. For the established system, more multimedia devices can be added and controlled by computer software to further expand the system.
