The characteristics of medical and health system and the demand of video communication;
1, which can be organically integrated with other digital medical systems and work together.
2. At the same time, it is integrated and decentralized: it can not only be purchased in most hospitals in a province or city, but also implement telemedicine systems and form a large-scale telemedicine network; It can also be purchased spontaneously by hospitals or academic institutions to achieve interconnection and consultation or training.
3, pay attention to practicality, in addition to teleconference, remote training, remote consultation, epidemic report and academic exchanges and other forms of application are more.
4. We need more multimedia data functions, such as enjoying pictures and texts, storing and sending slides, and annotating interactive electronic whiteboards. There are requirements for the quality of audio and video and the reliability and stability of communication, especially for remote consultation, which requires higher quality of video images. The network environment is relatively complex: national, provincial, medical schools or research institutions often have their own private networks and rich bandwidth resources, while municipal or county-level medical institutions do not have their own networks, so they need to rent networks with low communication rates such as ADSL and ISDN in the telecommunications sector. Different network environments need different products and solutions.
The video conference system of medical and health system can have many different applications, such as expert consultation, remote training, hospital rounds, industry meetings, administrative meetings (epidemic emergency command, epidemic report and notification), remote diagnosis and interactive public education. According to different application environments and uses of medical and health systems, VTEL makes full use of various video terminals (such as personal desktop terminals and conference room terminals) of VTEL, and selects appropriate access modes (including E 1, DDN, ISDN, LAN and ADSL). According to users' network conditions, it provides three different applications, including remote diagnosis solutions, remote training solutions and industry conference solutions.
