随着村村通广播电视事业的发展,使许多居住在偏远山区的人们也看上了电视。有些远离城市的农村为了解决看电视难的问题,建立了自己的小型闭路电视系统。这些小系统往往只供一个镇或一个村使用,所用传输系统为300MHz系统,这些小系统大多数由村里电工管理。但由于农村电工缺乏必要的测试仪器和维修技能,使有线电视系统的故障不能得到及时的维修,影响了广大群众的收看。
With the development of village-to-village radio and television programs, many people living in remote mountainous areas have also spotted television. Some villages far from the city set up their own small-sized closed-circuit television system to solve the problem of watching TV. These small systems are often used by only one town or village, and the transmission systems used are 300 MHz systems, most of which are managed by village electricians. However, due to the lack of the necessary test equipment and maintenance skills of rural electricians, failure of the cable television system can not be timely repaired, affecting the broad masses of people watching.
