Abstract
The invention presents a method of frame synchronization of Digital Video Broadcasting (DVB) data using a temporary storage area (regfile) of substantially smaller dimension than the repetition rate of the sync pattern. Synchronization is achieved by detecting the sync pattern by correlation and determining if the pattern has a fixed repetitive separation. The synchronization scheme of the invention is simple and easily implementable as an integrated circuit, using software and a microprocessor, or as discrete circuitry.
