Now, video conferencing has become the most advanced means of communication, then, what types of video conferencing system?
In Terms of Video Conferencing Technology Level
First, from the video conferencing technology to achieve the level of distinction, the current video conferencing systems are:
- TV Live Video Conferencing System
This system needs to rent a dedicated satellite channel, the transmission mode for the one-way transmission. To bidirectional transmission, it must be rented two channels. The cost of renting a satellite is very expensive and must also be complicated through approval. So this video conference system can only be used for some special industries such as television stations.
- MPEG1/MPEG2 Compression Format Video Conferencing System
MPEG1 requires a bandwidth of 5 Mb/s, MPEG2 requires a bandwidth of 3Mb/s, and the image quality drops sharply with the network transmission distance. Therefore, the system is usually only available for local high-speed network segments.
- Based on ITU (International Telecommunication Union) H.320, H.323 Series of Standards And MPEG4 Compression Format Video Conferencing System
The emergence of the system makes expensive video conferencing systems into commercial areas. As the MPEG4 standard set late, the first business development of the MPEG4 standard is not very uniform, which resulted in MPEG4 standard video conferencing system congenital compatibility. Currently in the market technology is mature and the real dominant is based on H.320 / H.323 standard video conferencing system.
In Terms of Video Conferencing Nature
Second, from the nature of video conferencing distinction, the current video conferencing systems are:
- Hardware Video Conferencing System
Hardware video conferencing is based on the embedded architecture of video communication, relying on DSP + embedded software to achieve video and audio processing, network communications and the conference function. As the current hardware video conferencing systems need to be equipped with high-performance DSP processor and dedicated operating system, so there are expensive and high risk of investment, maintenance operations and more complicated features.
- Software Video Conferencing System
Software video conferencing is based on the PC architecture video communication, mainly rely on CPU processing, audio codec work. Its biggest feature is cheap, and good openness, software integration convenience. It is also because of the advantages of software video conferencing systems, software video conferencing has now become the first choice for enterprises to set video conferencing systems.
- SaaS-based Video Conferencing System
With the rapid development of Internet communication in recent years, especially the rapid development of “cloud” technology, the software video conferencing system has emerged a new trend, that is based on SaaS platform video conferencing system. This type of video conferencing system is characterized by: users do not need to install video conferencing software server (or even a client), as long as the computer can access the Internet. The computer is equipped with audio and video output, so you can achieve remote video conferencing, remote interactive collaboration through the browser. Among the SaaS video conferencing system, ezTalks Cloud Meeting has 20 years of successful experience in video conferencing, which is one of the best.
