标准摘要
[中文适用范围]： 本国际标准描述了无线电数据系统@ RDS@，旨在应用于 87@5 MHz 至 108@0 MHz 范围内的 VHF/FM 声音广播，可以承载立体声（导频音系统）或单声道节目（如ITU-R 建议书 BS 450-3 和 ITU-R 建议书 BS.643-3）。 RDS 的主要目标是改进 FM 接收器的功能，并通过使用诸如节目识别、节目服务名称显示和@特别是便携式和汽车收音机的自动调谐等功能，使其更加用户友好。因此，相关的基本调谐和切换信息必须由类型 0 组实现（参见 6.1.5.1）@，并且与 RDS 中的许多其他可能功能不同，它不是可选的。 [外文原描述]： IEC 62106:2015(E) describes the Radio Data System, RDS, intended for application to VHF/FM sound broadcasts in the range 87,5 MHz to 108,0 MHz which may carry either stereophonic (pilot-tone system) or monophonic programmes (as stated in ITU-R Recommendation BS 450-3 and ITU-R Recommendation BS.643-3). The main objectives of RDS are to enable improved functionality for FM receivers and to make them more user-friendly by using features such as Programme Identification, Programme Service name display and, where applicable, automatic tuning for portable and car radios, in particular. The relevant basic tuning and switching information therefore has to be implemented by the type 0 group (see 6.1.5.1), and it is not optional unlike many of the other possible features in RDS. This third edition cancels and replaces the second edition, published in 2009 and constitutes a technical revision. It includes the following changes: - for the RDS feature EON and the use of group types 14A and 14B some additional explanations were added; - in Annex E, containing the character code tables to be used in RDS, the explanation for Table E.1 and Table E.2 was extended; - several small typing errors were corrected; - to Enhanced RadioText in Annex Q an additional explanation was added.
