With the development of the economy and the intensification of competition, the demand for video conferencing systems is increasing. Therefore, the trend of video conference has become a major problem that plagues various video conference software development units. A large amount of data in the study shows that the video conference system is mainly developed towards flexibility and ease of use, popularization and civilianization, and home miniaturization.
Flexible and easy to use
The number of corporate users in the video conferencing market is increasing. Some corporate CIOs often complain that traditional video conferencing products are too expensive and use dedicated lines or ISDN. The performance of software products is very unstable, inconvenient to use, and complicated downloading and installation steps and bandwidth The higher requirements have not been able to meet the basic needs of users. Users' concerns about flexibility and ease of use indicate that video conference systems need to further simplify operations and improve compatibility with other systems: most current video conference systems use hierarchical menus for control, and the operations are still more complex. Data sharing refers to using video conferencing systems to enable collaborators in different places to understand each other and share applications (such as electronic whiteboards, shared Windows applications, etc.). With the development of integrated video, audio, and data networks, especially in the fields of distance education and telemedicine, users will pay more attention to data and application sharing; flexibility is also very important for users. In the field of video communications, conference applications are just one of them. One part: more and more users hope that the video conference system has the function of distance education and can be combined with the office automation system to improve the management quality. As a communication network system, the video conference system is very important for its manageability and maintainability. A high-quality system that can be easily loaded and unloaded is very important for users who need to move and travel frequently. It is extremely necessary to improve the portability of the system without reducing the performance of the system. In short, enterprise users need a more flexible and easy-to-use video conference system.
Popularization
The development of the electronic information software industry has enabled ordinary users to enjoy high-definition video communications, which is no longer a distant dream. Now more and more video conferencing systems are improving the efficiency of work, enhancing the ability to collaborate and reducing the cost of official business, making them an important means of information exchange and transmission for government departments and various industries. From 2004, many government agencies and universities Medium-sized enterprises have begun to expand video conferencing systems to third- and fourth-tier cities. This development trend is primarily due to the development of broadband networks. At present, broadband networks are becoming more and more popular. The network broadband environment of some cities, counties, and towns is already close. Large central cities, which makes it possible to provide low-cost, high-quality, professional video conferencing services in the third- and fourth-tier markets. At the same time, the rapid advancement of e-government and enterprise informatization and the video systems of primary and secondary markets in some industries The successful application is also accelerating the expansion of the video conference market to third- and fourth-tier cities. Data show that, driven by this trend of civilianization, government offices have accounted for 46.6% of the total market share in the entire video conference market. In order to improve the operating model and work efficiency, the telecommunications, finance, railway, and power industries are also vigorously developing video conference systems. They have a market share of 33.2%. Compared with the above fields, distance education and telemedicine in China are still in the early stages of development, and their share is 8.7% and 7.9% respectively. This reflects that the video conference system is not strong enough in distance education, telemedicine and other aspects. However, according to our research, the application of these two fields has shown a booming trend in recent years, and once again strongly demonstrates the trend of popularization and popularization of video conferencing.
Home miniaturization
The video conference system can allow users in different places to conduct "face-to-face" communication, which undoubtedly brings many benefits to enterprises to improve work efficiency and save conference expenses. In the past, the mainstream of video conference systems were room-type behemoths. They were expensive and had always been the exclusive rights of large companies and bosses. Ordinary enterprises could not reach it. However, with the rapid development of computer technology, computer processing capabilities and network transmission capabilities have been greatly improved. Video conferencing systems have been miniaturized and gradually become acceptable to the public. At a time, SMEs and individual users have become video The largest potential stocks in the conference area. How to work at home like an office, how to use a video conferencing system on a personal PC without the need for a dedicated network and the need to occupy high bandwidth, has provided a fuse for the trend of home video and miniaturization of video conferencing. These three trends pose a challenge to the major video conference manufacturers in the market. With the increasing trend of popularization and miniaturization, the market has called for a communication tool suitable for daily communication among small and medium-sized enterprises, families or individuals. This tool must have the convenience of qq, msn, and strong data collaboration. Functions, and put forward higher requirements for audio and video effects. Following this trend, many manufacturers have begun to consider the transition of professional video conferencing to general chat software, but this chat tool must still maintain the high audio and video quality of professional video conferencing and possess the ease of use of current chat tools.
