Abstract

Настоящее изобретение относится к способу и устройству для передачи телевизионной информации в многочастотной системе связи. Сигналы синхронизации в системе передаются в диапазоне частот 1,25 Мгц, то есть на нескольких несущих частотах, по нескольким выбранным каналам синхронизации вместо передачи по каналам системы, выделенным для передачи данных. Сообщения, передаваемые по каналу синхронизации, могут содержать дополнительную информацию об основной несущей частоте в диапазоне выделенных частот. В качестве предпочтительных каналов для передачи сигналов синхронизации в системе персональных услуг связи могут быть выбраны каналы 75, 150 и 225. Такой выбор обеспечивает то, что один из предпочтительных каналов для передачи сигналов синхронизации будет всегда использоваться любой многочастотной системой передачи информации независимо от выбора канала, соответствующего основной несущей частоте.
