CA 2742348

An audience measurement system generates signatures of unknown pieces of content viewed by panel members, and generates reference signatures of known pieces of content. The signatures of the unknown pieces of content are stored and transmitted to a central processing site, .cndot. where they are compared with the reference signatures for their identification. A scanning engine finds matches between the signatures of the unknown and the known contents, and stores matches so as to build "tracking segments", i.e., strings of matches that indicate a coincidence between the unknown content and one or more known pieces of content for a certain period of time, and associates the unknown content to the known piece of content with the longest tracking segment.

Un système de mesure d'audience génère des signatures de contenus inconnus vus par les membres d'un panel, et génère des signatures de référence de contenus connus. Les signatures des contenus inconnus sont conservées en mémoire et transmises à un site de traitement central où elles sont comparées pour identification aux signatures de référence. Un moteur d'analyse trouve des concordances entre les signatures de contenus inconnus et connus et conserve en mémoire les concordances de façon à construire des "segments de suivi", c'est-à-dire des suites de concordances qui indiquent une coïncidence entre le contenu inconnu et l'un au moins des contenus connus pendant une certaine période de temps, puis ce moteur d'analyse associe le contenu inconnu au contenu connu du segment de suivi le plus long.
