Abstract
Un système (FIG. 9) de traitement de données comprend une application orientée logiciel qui permet d'extraire des données (FIG. 21) codées de réponse partielle d'un intervalle de suppression verticale d'un signal de télévision. Le système se synchronise sur un signal de synchronisation, tel qu'une rafale chromatique, et extrait les données (FIG. 4A-4B) codées à plusieurs niveaux. Le système peut comprendre plusieurs modes ayant des débits (FIG. 22) de transfert de données différents pour s'adapter à des environnements de transmission et des vitesses de transmission différents.
