Hardware video conferencing system and its characteristics
Hardware video is a video communication mode based on embedded architecture, which relies on DSP+ embedded software to realize video and audio processing, network communication and various conference functions. Its biggest feature is high performance, good reliability, most of the high-end video applications are used in the hardware video.
Hardware video conferencing system mainly includes embedded MCU, conference room terminal, desktop terminal and other devices. The MCU is deployed in the network center and is responsible for the processing and forwarding of the stream. The conference room terminal is deployed in the conference room and connected with peripheral devices such as cameras, microphones and televisions. The desktop terminal integrates a small camera and LCD display, which can be installed on the desk as a dedicated video communication tool.
Advantages of Hardware video conferencing system:
- High integration
Hardware video terminals can provide a variety of video and audio interfaces and network communication interfaces, and some have built-in video matrix functions, which can be used only by connecting peripheral video and audio input/output devices and accessing the network. The hardware multipoint control unit (MCU) can integrate various hardware modules such as multi-picture segmentation, data service, digital mixing, etc., and its integration is much better than the way that multiple servers run together in the software system.
2, with high safety and stability
Embedded architecture has a good anti-virus ability, more than 99% of the viruses circulating on the network can not attack the embedded system. The design based on DSP processor makes the hardware video conferencing equipment have very low power consumption and good stability, some high-end hardware video conferencing equipment also has the key processing unit backup, redundant heat dissipation, hardware AES encryption, firewall and other functions, to further ensure the security and reliability of the system, to achieve 7×24 hours of uninterrupted network operation.
3, video and audio effect is good
Due to the use of real-time operating system and efficient codec technology, the video quality of hardware video conferencing products is generally higher than that of software products, and video and audio synchronization is also easy to achieve. Hardware video conferencing products can integrate video preprocessing, video optimization, audio optimization technology to further improve the video and audio effect.
4, flexible operation
The hardware video terminal generally integrates the remote control function, and the personnel who are not familiar with the computer can set up and operate the video conference through the remote control and OSD menu. Of course, the hardware video conferencing system can also be set up and operated by a PC to facilitate the control and management of large meetings.
5, with a good QoS guarantee mechanism
The hardware video conferencing system can support various QoS technologies such as RSVP and Diff Serv, and ensure the good operation of video conferencing in the environment of poor network quality through various low-level control and processing technologies.
- Support a wide range of communication networks
The hardware video conferencing system can support both H.323 and SIP system standards, and can adapt to all kinds of network transmission conditions of special line or Ethernet.
