Time multiplexed reception on two carrier frequencies in digital broadcasting

摘要

A DAB (Digital Audio Broadcast) digital radio time multiplexed (T) signal receive circuit selects RDS (Radio Data System) type additional user information (S) from a second carrier frequency for storage and processing for use in intervals outside the time window of the demultiplexed signal being received from the first carrier frequency. Independent claims are included for time multiplexed signal reception procedures used by the circuit.
