Characteristics and Development of Digital Conference Systems

Published Date: 21 May, 2023

System composition and characteristics of digital conference system:

The digital conference system is an automated conference management system that integrates computer, communication, automatic control, multimedia, image, and sound technologies. The digital conference system generally consists of network subsystems, projection display subsystems, sound subsystems, monitoring subsystems, conference speech subsystems, lighting effect subsystems, and central control subsystems.

All subsystems share data and control information on the computer network platform, enabling decentralized operation and centralized control. This allows equipment operators to conveniently and quickly monitor and control all devices.

Its main characteristics are:

  • Digitization.

The digital conference system uses only digital signals for internal transmission, and the delegate microphone also uses “analog-to-digital” conversion technology. 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 equipment, etc.) can directly enter the digital system network through the audio media interface.

  • Modularization.

Any level of conference requirements can be met by selecting suitable devices through modularization to compose corresponding systems. For established systems, more multimedia devices can be added for further expansion of the wireless conference room sound system through computer software control.

Analysis of the development direction of the digital conference system:

The digital conference system includes digital conference discussion systems, digital conference voting systems, conference subtitle systems, IC card check-in systems, name plate conference system, and conference camera tracking systems. The digital conference system connects independent subsystems of conference reporting, speaking, voting, translation, filming, sound, display, network access, etc. to form an organic whole. The central control computer coordinates the work of each subsystem according to the conference agenda, providing the most accurate and timely information and services for various large-scale conferences and remote conferences, and configuring perfect management software. This simplifies the conference equipment while allowing for easy expansion of functions.

The main development directions of the future digital conference system are analyzed as follows:

  • Application of streaming media technology.

Streaming media refers to media formats played on the Internet using streaming transmission. Streaming media is also called streaming media, which means that merchants use a video transmission server to send programs as data packets and transmit them to the network. Users unpack the data through the decompression device, and the program will be displayed before sending. A series of related packets in this process are called "streams." Streaming media actually refers to a new media transmission method, not a new media.

  • Application of visualization and virtual reality cooperation.

Visualization is a theoretical, methodological, and technical approach that uses computer graphics and image processing techniques to convert data into graphics or images displayed on a screen and interactively processed. Visualization technology was first used in computer science and formed an important branch of visualization technology-scientific computing visualization. Scientific computing visualization can convert scientific data, including measured values, images, or digital information involved in calculations, into intuitive graphical and spatial changes in physical phenomena or physical quantities represented by graphics and images, allowing researchers to observe, simulate, and calculate.

  • Wireless transmission and mobile digital conference systems.

Wireless technology is developing rapidly. The application of wireless transmission technology is increasingly accepted by various industries. The development of the conference system will gradually free itself from the constraints of wires and enter the era of free wireless. Wireless is considered a significant development trend of the digital conference system.
