1. Conference system includes: basic microphone speech management, representative personnel inspection and attendance registration, electronic voting function, detached from the computer and the central control of the automatic video tracking function, data distribution and display, and multilingual simultaneous interpretation. It is widely used in monitoring, command, scheduling systems, public security, fire, military, meteorology, railroads, aviation and other monitoring systems, video conferencing, query systems and other fields, favored by users.
2. The most basic conference system, by the microphone, amplifier, audio, desktop display equipment (such as desktop intelligent terminals, LCD monitors), the combined application of these devices can also be said to be a conference system, they play a role in sound transmission, display, sound reinforcement to achieve the ability to see, hear and speak.
such as:
I, according to the equipment configuration
① Conference room conference system
Conference room conference system will be arranged in the meeting place in a dedicated conference room. In the conference room is equipped with specialized high-quality hardware and software, large screen monitors and sound systems. The system usually uses a dedicated broadband communications channel, which provides participants with near broadcast-quality video communications and therefore good video. This system is mainly used for large-scale meetings with a fixed location and time.
② desktop conferencing system
Personal computers ( PC ) is a common desktop processing tools. The conference system video and audio codecs and communication interfaces integrated into the PC can constitute a desktop conference system. Desktop conference system using public **** communication network communication. The use of desktop terminals can be at any time to participate in remote meetings and discuss issues with others. Desktop conferencing equipment is relatively inexpensive, and the video quality is below the professional level.
Two, divided by computer equipment
①Videoconferencing system
Videoconferencing is a television system used for conference purposes, the transmission of the main audio-visual signals, but also can be used to transmit the meeting documents with a fax machine and information cameras and other auxiliary equipment. Videoconferencing terminals are generally installed in specialized conference rooms for large meetings.
② computer conference system
Computer conference system is a computer as the terminal of the conference system. The use of computers can be effective control and management of the meeting. Participants are highly interactive and can realize the application programs and workspace **** enjoyment.
Computer conferencing can be divided into asynchronous and synchronous meetings.
In asynchronous meetings, the meeting users do not have to be active at the same time, can be held through the bulletin board, e-mail communication meeting. Whereas in synchronous meetings, all users are active at the same time and they communicate using real-time video, audio or data messages.
Three, according to the type of information flow
① Audio-graphic conferencing system
Audio-graphic conferencing system mainly utilizes voice for multi-party exchanges and is supplemented by communication equipment such as fax machines to transmit graphic files. This is an early form of conference system.
②Video conferencing system
Video conferencing is the use of digital video compression technology in the meeting using video information streaming system, this type of system is also known as audio-visual conference. In a meeting, participants can not only hear other people's voices, but also see other people's gestures and facial expressions.
③ Data Conferencing Systems
Data conferencing systems are conferences that utilize computer systems to exchange data information over narrow bandwidth communication networks. The conference can be in synchronous or asynchronous form. Running on the conference terminal is a user data application program.
Four, multimedia conferencing system
The information flow in multimedia conferencing is real-time audio, video and other multimedia data. At the same time, as a support tool for collaborative work, the multimedia conferencing system supports user applications **** enjoyment, providing electronic whiteboards and text conversation programs that depict discussions. The concept of multimedia is expressed not only in the form of information flow, but also in the integrated *** enjoyment of space, multi-user interactivity and consistent control of multimedia information.
Fifth, the virtual meeting system
Virtual meeting system is the advanced form of the conference system. With the conventional conference system using a different form of video window, virtual meetings in the participants appear in a unified virtual venue. Multi-point control equipment ( MCU ) mixed received audio and video streams, in the encoding state to generate a virtual meeting room, and the mixed conference stream to each participant, each user's video stream is at its corresponding terminal by the video and audio data generated by the calculation.
