ABSTRACT:
An apparatus and method for accurate synchronization with inbound audio data which packets at relatively low sampling rates. By using previously known information such as the time of arrival of the beginning of the data packet, a reference timer in a digital signal processor can be used to calculate a number of samples and/or portions thereof between a beginning reference time and the beginning of a data packet, and then calculate the timing error between the first sample point after the arrival of the data packet and the beginning of the data packet. Using this information, the actual arrival of the data packet can be derived and utilized to very accurately, within very small margins of error, synchronize the beginning of the data packet with the scrambling algorithm used in the receiver.
