What is the difference between a software video conference terminal and a hardware video conference terminal?

First, the advantages of hardware video conferencing system? ：

1, high integration: the hardware video terminal can provide a variety of video and audio interfaces and network communication interfaces, and some of them also have built-in video matrix functions, which can be used by simply connecting peripheral video and audio input/output devices and accessing the network.

2, with high security and stability? Embedded architecture has good anti-virus ability, and more than 99% viruses circulating on the network cannot attack embedded systems. The hardware video conference equipment based on DSP processor has low power consumption and good stability. Some high-end hardware video conferencing equipment also has the functions of key processing unit backup, redundant heat dissipation, hardware AES encryption, firewall and so on, which further ensures the safety and reliability of the system and realizes the uninterrupted operation of the network for 7×24 hours.

3. Good video and audio effects: Due to the adoption of real-time operating system and efficient coding and decoding technology, the video quality of hardware video conferencing products is generally higher than that of software products, and the synchronization of video and audio is also easy to achieve. Hardware video conferencing products can integrate video preprocessing, video optimization and audio optimization technologies to further improve the video and audio effects.

4. Flexible operation: hardware video terminals generally integrate remote control function, and people who are not familiar with computers can set up and operate video conferences through the remote control and OSD menu. Of course, the hardware video conference system can also be built and operated by PC, which is convenient for the control and management of large-scale conferences.

5. Is there a good QoS guarantee mechanism? The hardware video conference system can support various QoS technologies such as RSVP and Diff Serv, and ensure the video conference to run well in the poor network quality environment through various underlying control and processing technologies.

6. Support a wide range of communication networks? The hardware video conference system can support both H.323 and H.320 system standards, and can adapt to various private line or Ethernet network transmission conditions.

Second, the shortcomings of hardware video conferencing system:

1, the price is slightly higher.

2. Desktop expansion needs software support.

3. Large initial investment

Third, the software video conference system and its characteristics:

1. Software video is a video communication mode based on PC architecture, which mainly relies on CPU to encode and decode video and audio. Its biggest characteristics are low price, good openness and convenient software integration and deployment. However, the stability and reliability of software video need to be improved, and the quality of audio and video can not surpass that of hardware video system. Its current market is mainly concentrated in individuals and enterprises.

2. Software video conference system is an important application of software video, which mainly adopts the structure of server +PC. Deploy MCU server, multi-screen processing server and streaming media server at the central point; Configure USB camera, earphone and conference terminal software on ordinary desktop PC; Configure high-performance PC, video capture card, conference camera and conference terminal software in the conference room. When holding a video conference, use a Windows-based user interface to set up and manage the conference.
