What is the composition of the video conferencing system?

1. The composition of the video conferencing system generally includes four parts: terminal equipment, multi-point control unit (MUC), network management system and transmission network.

2. Video conferencing system IIt generally includes four parts: video conferencing terminal, video conferencing server (MCU), network management system and transmission network: video conferencing server (MCU): as a video conferencing server, it is equivalent to a switch.

3. The video conferencing system includes the following equipment: video conferencing terminal: including software terminal and hardware terminal. Audio and video equipment: including microphones, cameras, display equipment (projection, TV, TV wall) and audio. Other devices: including recording and broadcasting servers, storage servers, conference gateways, etc.

4. Intelligent central control system Intelligent central control system can centrally control various equipment such as sound, light and electricity. It is generally used in multimedia conference rooms, electrochemical classrooms, monitoring and guidance centers, press release rooms and other places.

5. A complete video conferencing system is usually composed of five major parts: video conferencing terminal, multi-point control unit MCU, network management software, transmission network and related accessories.

What are the network conference systems

Webconferencing systems include: Tencent Conference, Hovision, Cisco WebE xMeeting, Zoom, attention, etc.Tencent Conference Tencent Conference is a special video conferencing software launched by Tencent in addition to enterprise WeChat. It claims to provide one-stop cloud conference solutions based on Tencent's more than 20 years of audio and video communication experience.

It is classified according to the signal transmission medium: it is divided into telephone (telecommunications network) conference system, video conference system and computer network conference system. It can be divided into analog and digital conference systems according to the continuity of the signal.

-Boom video conferencing Boom, as a simple high-quality cloud video conferencing system, can realize various forms of conference communication such as audio and video communication, data interaction, remote assistance and content sharing in a low-bandwidth network environment. It can be used in enterprise meetings, remote training, government party building, telemedicine and other fields.

I think the intelligent conference systems are Kebest, Lanling Software, Jinghuitong and Daotianqin.

Which video conferencing system is better?

1, TOP. Huawei HUAWEI video conferencing system. TOP.POLYCOM video conferencing system. In terms of function, domestic products are better, because they are originally designed for domestic users, and they think domestic products are better in terms of usage habits and functional habits. The domestic brands are probably: Huawei, Huaping and ZTE.

2. Therefore, if the government department chooses video conferencing, you can try Huawan's Zhongmu video conferencing software.

3. Better systems for intelligent conference: Dingding, Hashitong, Tencent Conference, Tianyiyun, Xiaoyu Yilian, etc.

videoThe functions of the frequency conference system include

1. The functions of the video conference system generally include: multi-party audio and video interaction, electronic whiteboard, dynamic PPT, file sharing, collaborative browsing, media playback, desktop sharing, text communication, and conference recording.

2. The functions of the video conferencing system include video interaction function, audio communication function, text conversation function, synchronous recording function, document sharing function, real-time live broadcast function, screen sharing function, etc. Video interaction function In video conferencing, what is more important is the video display.

3. The functions of the video conferencing system generally include video calls, screen sharing, file sharing, real-time chat, multi-party calls, recording functions, etc. Video calls allow participants to have real-time video communication through the camera and see each other's facial expressions and body language.

Introduction to seven ways for video conferencing systems to access the network

At the same time, satellite communication is delayed, which is not suitable for video conferencing systems with high real-time requirements. Frame relay mode Frame relay access mode is also a professional conference access method.

– Encrypted conference: the maximum access bandwidth is 3Mbit/s. In addition to the terminal itself, it can also access up to 3 576p 30fps video venues, and the maximum access bandwidth of each video venue is 1Mbit/s. L Support access to H.32SIP type HD, SD video venues and pure audio venues.

The access mode of IP metropolitan area network is generally divided into LAN access (network cable) andFTTX access (optical fiber): LAN access refers to pulling the network cable directly to the user's home from the node of the metropolitan area network through the switch and hub.

What equipment does the video conferencing system include

Projection display equipment is the main presentation part of the video conferencing system. Among them, display equipment can also be called monitors, or directly and commonly referred to as display screens, screens, etc., such as TV display equipment and curtain display equipment. Projection equipment is distinguished by projection method. There are three ways: positive projection, back projection and combination splicing.

Video conferencing system includes: hardware video conferencing: traditional hardware video conferencing generally includes video conferencing terminals, MCUs, network switching equipment, etc., but with the application of cloud computing technology,In cloud computing video conferencing equipment, users do not need to buy MCU, but only need to install the video conferencing terminal.

Microphone Microphone is one of the necessary equipment for remote video conference rooms. It can transmit the voice of participants to the video conference terminal to ensure the audio clarity and stability of the meeting. The selection of microphones should consider factors such as sound clarity and anti-interference ability to ensure the clarity and stability of the audio.

The video conferencing system includes the following equipment: video conferencing terminal: including software terminal and hardware terminal. Audio and video equipment: including microphones, cameras, display equipment (projection, TV, TV wall) and audio. Other devices: including recording and broadcasting servers, storage servers, conference gateways, etc.

Audio equipment includes microphones, speakers and audio systems are used to ensure that participants can hear and make sounds clearly to ensure the smooth progress of the meeting.
