近年在欧美出现了一种新颖的广播系统。在欧洲为RDS广播,北美称RBDS广播,两者均为无线电数据广播。 什么是无线电数据广播,它有什么优越性? 你问问常用收音机的人,他收听的电台有几个,栏目又是哪些。给你的回答多半很简单,因为,大多数人总是听这么几个电台和栏目。而当今天空中,电台节目真是太多了,而人们没法使用,其原因主要是寻找电台太困难。PLL功能虽然解决了找台部分的困难,但你对每个台的节目程序,节目内容还是记不住很多。RDS和RBDS就是针对上述弊病而发展起来的。
In recent years there has been a new type of broadcasting system in Europe and the United States. RDS broadcast in Europe and RBDS broadcast in North America, both of which are radio data broadcasts. What is radio data broadcasting, what are its advantages? You ask the people who use the radio, how many radio stations he listens to, what are the columns. The answer to you is mostly simple, because most people always listen to these few radio stations and columns. In today’s sky, there are so many radio programs that people can not use. The main reason is that finding a radio station is too difficult. Although the PLL function to solve part of the difficulties to find Taiwan, but you program each program, program content or not remember a lot. RDS and RBDS are developed against the above shortcomings.
