Abstract
A method and a system for recognizing, by a broadcasting platform, content sequences of an input linear content stream by retrieving content information determined by small fingerprints of portions of the linear content and comparing the small fingerprint with reference fingerprints stored in a database. The output stream transmitted to the user units is modified by the addition of a synchronization stream including at least identifiers of the content sequences and associated temporal information determined on the basis of the reference fingerprints. The content information is exploited by the broadcasting platform or the users units for replacing a sequence by anther one, removing predefined sequences, skipping or forcing viewing content sequences, The initial linear content stream is thus enriched with accurate content information allowing the viewer to navigate and select the content to play either in live or replay mode. A back in time feature may also be introduced allowing navigating back and forward inside a content currently played.
