无线数据广播系统(Radio Data System,RDS)能在调频广播发射信号中利用副载波把电台名称、节目类型、节目内容及其它信息以文字形式发送出去。文章介绍了利用RDS传送广播文本的方法,首先分析RDS的原理、消息格式和编码结构,之后详细解说了广播文本这个组型的结构与编码方式,然后用一个具体的例子通过RDS编码生成了广播文本信息。最后,实验结果验证了其传输广播文本的正确性。
The Radio Data System (RDS) can use subcarriers to transmit station names, program types, program contents and other information in text form on FM broadcast transmissions. The article introduces the method of using RDS to transmit broadcast texts. First, we analyze the principle, message format and encoding structure of RDS. Then we explain the structure and encoding of broadcast texts in detail, and then use a specific example to generate broadcasts by RDS encoding Text message Finally, the experimental results verify the correctness of the transmitted broadcast text.
