First, based on the equipment configuration 1. Conference Room Conference System The conference room conference system is designed for use in a dedicated space, typically a well-equipped meeting room. This system integrates high-quality hardware and software, including large-screen displays, advanced audio systems, and reliable video conferencing tools. It often relies on a dedicated broadband connection to ensure clear and stable communication, delivering near-broadcast quality video and sound. This setup is ideal for formal, large-scale meetings that require a fixed location and schedule. 2. Desktop Conferencing System A desktop conferencing system allows users to participate in remote meetings using their personal computers. By integrating video and audio codecs along with communication interfaces into the PC, it enables real-time interaction over public networks. This system offers flexibility, as users can join meetings from anywhere at any time. However, the video quality is generally lower than that of professional systems, and the cost is more affordable, making it suitable for smaller or less formal discussions. Second, based on computer equipment 1. Video Conferencing System A video conferencing system is specifically designed for visual communication during meetings. It primarily transmits video and audio signals, and can also share documents using additional devices like fax machines or data cameras. These systems are commonly installed in dedicated conference rooms and are used for large-scale, face-to-face meetings where visual presence is important. 2. Computer-Based Conference System A computer-based conference system uses computing technology to manage and control meetings efficiently. It supports interactive participation, allowing users to share applications, workspaces, and files. These systems can be categorized into asynchronous and synchronous types. In asynchronous conferences, participants do not need to be online simultaneously; they can communicate through email or message boards. Synchronous conferences require all participants to be active at the same time, using real-time video, audio, or data transmission for instant interaction. Third, based on the type of information flow 1. Audio and Graphic Conferencing System This system mainly relies on voice communication, with graphic file sharing facilitated by devices such as fax machines. It represents an early form of conferencing technology, focusing on basic audio and document exchange rather than full video interaction. 2. Video Conferencing System Video conferencing utilizes digital compression techniques to transmit real-time video and audio during meetings. It is also known as audiovisual conferencing. Participants can see each other's facial expressions and body language, enhancing the sense of presence and engagement. This system is widely used in both business and educational settings for remote collaboration. 3. Data Conferencing System A data conferencing system enables the exchange of data over narrow bandwidth networks. It can operate in either synchronous or asynchronous modes, depending on the needs of the participants. The system runs on the conference terminal, allowing users to access and share data applications in real time. Fourth, Multimedia Conference System Multimedia conference systems handle real-time streams of audio, video, and other media. They support collaborative work by enabling shared applications, electronic whiteboards, and text chat features. Beyond just transmitting data, these systems create an integrated environment that fosters multi-user interaction and synchronized control of multimedia content, making them ideal for complex, interactive meetings. Fifth, Virtual Conference System A virtual conference system represents an advanced evolution of traditional conferencing. Instead of displaying participants in separate video windows, it creates a simulated virtual meeting space. The Multipoint Control Unit (MCU) combines incoming video and audio streams, generating a unified virtual room. Each participant receives the mixed stream, and individual video feeds are rendered in real time based on the data received. This approach enhances the immersive experience and makes remote meetings feel more natural and engaging. The water glass shell process has low cost, simple operation, and low requirements for raw materials. The basic feature of the process is the use of paraffin-stearic acid low-temperature mold material, and the use of water glass as the binder in the process of shell making. In terms of shell process, its surface quality is average, and its dimensional accuracy is not as high as that of silica sol process, but because of its unique cost, it is widely used in some civil and low-precision internal combustion engines in my country.
