Modern information technology has been widely used in information industry. Multimedia communication is the product of the combination of multimedia technology and communication technology, which combines the interactivity of computers, the distribution of communication networks and the comprehensiveness of multimedia information, and provides people with brand-new communication services. At present, economically developed countries have invested heavily in developing hundreds of multimedia application systems. The application of multimedia communication mainly includes the following aspects: videophone, video conference, telemedicine service, teaching and training, multimedia mail, consultation and service, etc. For example, telemedicine service, after computer input into comprehensive medical information system, medical automation and intelligence will become possible. When the patient speaks into the computer terminal, the computer can tell the patient or nurse whether the patient needs to see a doctor or what kind of doctor he should see. With the application of multimedia computers, TV network can not only meet the long-distance communication between doctors and patients, but also enable doctors to seek expert advice and connect doctors' offices, consulting rooms, beds and laboratories. Access to better medical services is a major application of new information technology.
Multimedia communication technology can make fundamental changes in education. Education will provide people with educational services in various new forms. The TV network employs well-known teachers to teach, and high-level teachers can make teaching videos or write computer-aided teaching software. In this way, as long as we have the best teachers and the best teaching content, we can use the TV education system to help people realize auxiliary teaching and learning at a convenient time through computers and receive education without geographical restrictions.
Informatization has become an important trend in the development of the world today. In order to make the information system exert greater economic and social benefits, it is necessary to realize digitalization of information resources, serialization of software services, socialization of information consultation, networking of information access and standardization of information service management. Of course, if we want to realize it, we must use computer technology, optical fiber technology, optical storage technology and multimedia technology. We can't predict the future world, but we can't always live in the fantasy of it, but we should challenge it and challenge a better tomorrow.
The world we live in now is made up of the known and the unknown. The more we know, the bigger the unknown area. The vast unknown field constitutes the unknown world that we are eager to explore. The unknown world has a charm, which always attracts us to make a breakthrough when we find the truth in the unknown field, rather than sticking to the rules all the time.
The 21st century will be the information age. With the development of information science and technology, computer network, communication network and cable TV network will be greatly combined. At that time, people could work from home. As long as you turn on the computer, you can get in touch with leaders and colleagues, exchange information, ask for instructions and report, and discuss problems, which is very convenient. After work, it is relaxing and enjoyable to browse business information, stock market, football match or shopping online. Information science and technology will bring new ways of working and living to mankind.
