Author: Zhao Yajun Teacher: Li Yulin
[Abstract] With the development of modern educational technology and long-distance education, TV education becomes an important form of school education. Many schools have built systems of CATV. But most of these systems were built in the late 1990s and were hardly suitable for the school education’s need in a fast developing time. Being according to the present conditions of school education construction in China, this article gives you a feasible plan. It called receiving system of the satellite & two-way transmission of cable. This system of CATV is suitable for most of schools. It can give the signal to every classroom and take back the situation of teaching in classroom on the air by the TV network. It brings about two-way transmission. This system has preponderances of low cost of equipment, short time limit for project, wide transmission band, and the desired effect quickly. It is fit in with different kinds of schools needed two-way transmission.
