[摘 要] 随着现代教育技术和远程教育的发展，电视教育成为学校教学活动的一种重要形式。很多学校已经建设了有线电视网络，这些系统多为上世纪90年代中后期建成，已经很难与快速发展的学校教学需要相适应。本文根据我国校园建设状况，提出了一套可行性方案，即：卫星接收邻频前端系统+电缆双向传输。一个很适合广大校园的有线电视系统，这个系统既能将有线电视信号传输到每一间教室,还可以把教室的授课情景通过有线电视网络进行实况转播，实现双向传输。该系统具有传输频带宽、设备成本低、建设工期短、见效快等优势，适用于需要实现双向信号传输的各类学校。

The System of School CATV Designs the Construction
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.
