Abstract
A method and receiving device are provided that determine a synchronization byte in a plurality of transport stream packets, wherein the synchronization byte has a predetermined synchronization value. The method/receiving device receives, via a receiver, a portion of a first transport stream packet of the plurality of transport stream packets; detects, starting from the beginning of the portion of a first transport stream packet, a continuous four byte pattern that does not include the predetermined synchronization value; detects a first occurrence of a byte having the predetermined synchronization value; detects a subsequent byte separated from the first occurrence by a predetermined byte length; determines a byte value of the subsequent byte; and validates that the first occurrence is the synchronization byte based on a comparison of the byte value and the predetermined synchronization value.
