Method and system for injecting sub-synchronization signals

摘要

A system and method of communicating sub-synchronization information into a transmitted digital audio stream and extracting sub-synchronization information from a received digital audio stream is provided. The method includes the steps of having a transmitter (50) introduce sub-synchronization information (S) into a data stream at a period less than that of existing pre-amble signals (FSPs), and transmitting that data to a receiver (40). The method further includes the steps of receiving the transmitted data stream in the receiver (40), extracting the synchronization information (S), and using the synchronization information (S) to accurately decode the received audio data.
