DIGITAL DATA STREAM PROCESSING

摘要

The invention relates to a method for processing a digital data stream including sequences and intersequences, wherein said method comprises a step (E1) of cutting the stream into segments on the fly and calculating signatures for said segments, and a step (E2) of detecting intersequences during which the following operations are applied to said stream on the fly: a first detection of intersequences by separation detection; the supply of a reference base (BR) with at least the signatures of the intersequences detected by the first detection; a second detection of intersequences by comparing the signatures of the stream segments obtained during the cutting step (E1) with the signatures of the intersequence segments contained in the reference base (BR).
