无线电数据系统（RDS） 频率范围从 64.0 MHz 到 108.0 MHz 的 VHF/FM 声音广播 第9部分：RBDS 在北美使用的 RDS 变体

[中文适用范围]： IEC 62106 的这一部分指定了无线电广播数据系统 (RBDS)，它是北美国家/地区使用的 RDS 兼容变体。 RBDS 于 1993 年首次由美国国家无线电系统委员会 (NRSC) 标准化，随后于 1998 年、2004 年、2005 年进行了修订 [外文原描述]： IEC 62106-9:2021 specifies the Radio Broadcast Data System (RBDS), which is an RDS-compatible variant used in countries of North America. RBDS was first standardized by the U.S. National Radio Systems Committee (NRSC) in 1993 and subsequently revised in 1998, 2004, 2005 and 2011 . With the publication of this edition of IEC 62106, the RDS and RBDS standards are now harmonized into a single document. The frequency range of operation (64,0 MHz to 108,0 MHz as indicated by the title of this document) varies according to regional regulatory authority. The U.S. range is 88 MHz to 108 MHz, as set by the U.S. Federal Communications Commission.
