Abstract: Packets in a bitstream are delineated by a) employing a first in, first out buffer (FIFO) with a storage capacity equal to the number of bits in a packet plus the number of bits in the synchronization pattern arranged so that comparison of its head end and tail end with the data pattern of the synchronization data pattern may be made, and b) declaring that a packet is detected when both the head end and the tail end of the FIFO each, substantially simultaneously, contains information equal to the synchronization pattern. Advantageously, the invention may be employed whether or not the bitstream is byte-aligned.
