CATV is a short way of saying "community antenna television.”but "cable television” is the term most people use. cable television allows viewers to receive TV programs that they cannot pick up with their regular antennas.
television signals do not follow the curve of the earth.they travel in straight lines in all directions. signals from a TV station move toward the horizon and the go into space. if you live only a few miles from a station, you may not get any picture at all.
CATV began in 1984. people in places far from TV stations shared the cost of putting up high antennas, a community antenna was usually placed on a hill, a mountain, or on a high tower. the antenna picked up TV signals and fed them into a small local station. from the station thick
wires called cables ran out to nearby homes. each person using the cable paid a monthly charge.
CATV worked well, and soon new uses were found for it, local stations could feed programs into empyty channels that were not in use. people along the cable could have local news, weather reports , and farm and school news at no extra charg.
today, cable television has moved into cities. it brings in extra programs that city viewers whith regular antennas cannot see. it is also used in many classrooms throughout the country.

CATV是"社区天线电视"一种简单的说法,但是有线电视才是大多数人使用的称呼.有线电视可以让观众们接收到用普通的天线不能收看到的电视节目.
电视信号的传播并不是地球的幅线的形状.它们是向着不同的方向以直线传播.电视信号从某电视台发出,直接沿着地平线方向进入太空.如果你住在电视台数英里的地方,也许你连任何图象都收不到.
CATV从1894年投入运营.住在远处的人们分摊了铺设高天线所需的成本.社区的天线也经常被安置在山丘,高山,或者高塔上.天线接收但是信号并把它们送入地方电台.从电视台的厚厚的线路,通常我们称之为电缆,信号通过它们被延伸到附近的居民家中.而使用缆线的人们也按月交纳费用.
CATV运作良好.很快的新用途也随之诞生.当地电台可以在那些没有使用的频道插入自己的节目.使用缆线的人们可以无须交纳额外的费用就可以看到地方新闻,天气预报,农场和学校的新闻.
今天,城市里的人们也开始使用有线电视.它为城市里的观众带来了常规天线收看不到的节目.有线电视也被应用到全国许多的教室中来.
恩恩,按你的要求,现在半夜两点了还在翻哦!
