The present invention relates to circuitry and an associated method for detecting a synchronization signal in a multi-media data transmission system. Preferably, the circuitry (10) includes process controller (40), memory (44), and a comparator (46). The process controller (40) controls the receipt of bit groups of data (52) and the storage of the bit groups of data (50) in the memory (44). The memory (44) operably couples to the process controller (40), receives the data, and stores the data in a predetermined order based upon the process controller (40). The comparator (46) couples to the process controller (40) and the memory (44) and compares the corresponding index locations of the bit groups (52) to a synchronization pattern (58). When the synchronization pattern (58) matches the predetermined set of bit groups (52), the comparator (46) generates the synchronization detection signal (60). The synchronization detection signal (60) then allows further equipment within the receiver to selectively operate on the data blocks received.
