Abstract[English]
Techniques are described for expanding and/or improving the Advanced Television Systems Committee (ATSC) 3.0 television protocol in robustly delivering the next generation broadcast television services. In a boundary region (302) between first and second broadcast stations (304) in which a receiver (300) can pick up signals from both stations, a primary tuner (502) presents (600) a demanded service while a secondary tuner (502) scans (602) for duplicate transmissions of the service and tunes to it if found. When the primary tuner loses signal (606), it tunes (608) to the frequency of the secondary tuner and acquires (612) any missing NRT data recorded from the secondary tuner prior to the handover.[French]
L'invention concerne des techniques destinées à étendre et/ou améliorer le protocole de télévision ATSC (Comité des systèmes de télévision avancés) 3.0, par la fourniture robuste des services de diffusion télévisée de nouvelle génération. Dans une région limite (302) entre la première et la seconde station de radiodiffusion (304) dans laquelle un récepteur (300) peut capter les signaux des deux stations, un syntoniseur primaire (502) présente (600) un service demandé tandis qu'un syntoniseur secondaire (502) recherche (602) des transmissions dupliquées du service et le syntonise s'il est trouvé. Lorsque le tuner primaire perd le signal (606), il s'accorde (608) sur la fréquence du tuner secondaire et acquiert (612) toutes les données NRT manquantes enregistrées à partir du tuner secondaire avant le transfert.
