补充资料:辅助业务信道广播
      利用多路传输技术,在一个声音广播频道中,除广播声音节目外,还广播业务信息。它已在调频广播中得到实现。其方法是在声音节目信号频谱的上方设置一个副载波,这个副载波受业务信息信号调制后与声音节目信号一起去调制主载波,从而使业务信息与声音节?慷嫉玫焦悴ァ?
  
  辅助业务信道广播已用于 3方面:①发射台与发射台之间的业务通信 (包括通话、远动信号和数据等的传送);②向接收者提供进一步的服务。例如节目识别,接收机的自动调谐和切换,盲人教育,为旅馆提供背景音乐、数据传送等;③播送其他业务信号。例如关于地震、火山爆发、核电站泄漏等灾害的紧急报警广播,指导驾驶人员的公路交通广播等。
