Abstract
Divers systèmes et méthodes de comparaison de signaux média sont décrits. Selon certains modes de réalisation, des signaux média sont comparés en relevant des caractéristiques de chaque signal puis en analysant ces caractéristiques pour déterminer si les signaux contiennent du contenu correspondant. Selon dautres modes de réalisation, les caractéristiques sont analysées pour déterminer lampleur de la synchronisation temporelle des signaux.
