METHOD AND DEVICE FOR DELINEATING A DATA STREAM AND COMMUNICATION SYSTEM COMPRISING SAID DEVICE

摘要

The present invention is directed at a method of delineating a data stream transmitted by a communication system using a protocol stack. According to the invention, the method consists in utilizing the redundancy of sequences whose content is fixed on one or more layers in a protocol stack so as to delineate packets which are or are not erroneous in a continuous data stream; the method consisting for this purpose in searching at the level of the receiver for the sequences corresponding to a known sequence SP present on the stream received, doing so by detecting sequences similar to this known sequence, the non-similar sequences not being retained; the method consisting moreover, in the presence of similar sequences, in storing their position so as to determine the start of the packets.
