Wide Range Of Video Conferencing Applications

 Wide range of video conferencing applications

Video conferencing systems are gradually shifting from high-end dedicated markets to low-end and mid-end markets, and their applications extend to areas such as external collaboration, business negotiation, internal communications, remote training, and paperless office.

Especially after enterprises and government agencies recognize the role of video conferencing and value-added functions, video conferencing is gradually integrated into the corporate network and e-government network.

The early video conferencing systems were mainly used in government and large-scale industry users. Now video conferencing systems are gradually shifting from high-end dedicated markets to low-end and mid-end markets. Their use far exceeds the scope of traditional executive meetings and office meetings, and the scope of application extends to Internal communication, external collaboration, business negotiation, remote training, paperless office and other fields. Especially after enterprises and government agencies recognize the role of video conferencing and value-added functions, video conferencing is gradually integrated into corporate networks and e-government networks. The demand for conference rooms and desktop conferences is strong.

At present, the mature and dominant technology in the market is a video conferencing system based on the H.320 or H.323 standard. The H.320 system is a dedicated solution for circuit-switched networks, and the H.323 system is an open solution for packet-switched networks. The H.323-based IP video conferencing system is gradually recognized by enterprise users. Considering compatibility and interoperability, mainstream manufacturers' video products support H.320 and H.323 dual-mode operation to protect user investment. With the improvement of computer computing power and the increasing network bandwidth, software video conferencing systems based on MPEG4 video compression standards are becoming more and more mature, and are favored by small and medium-sized enterprises.

Video conferencing solutions are highly specialized, and users' needs, venue points, and network environment are all factors to consider. Video conferencing requires very high real-time performance. When selecting a video conferencing solution for an enterprise, it is important to pay attention to the network environment and deploy a corresponding video conferencing bearer network. For business users, the stability and high quality of video conferencing is critical. Due to network conditions, video conferencing systems were mainly used in private networks in the past few years. In the field of professional video conferencing, H.320 systems dominated. In recent years, with the improvement and development of broadband networks, the stability and reliability of IP networks have been continuously improved, and the application of H.323 video conferencing systems based on IP networks has developed rapidly. However, the QoS problem based on the IP network has not been fundamentally solved. Problems such as network jitter, packet disorder, and network congestion may cause the stability of the conference system to be low. When the problem is serious, the conference may not even proceed normally. At present, the mature conference room-level video conferencing system requires a bandwidth of 384K. In practical applications, a dedicated private network and an IP private network are generally required, and users with low requirements may consider using the Internet.
