Abstract

Un récepteur reçoit un signal numérique. Ce signal numérique contient une trame de données BLA et ATSC robustes, ainsi qu'une carte. Cette carte contient les informations relatives à l'emplacement des données BLA et ATSC dans la trame. Un décodeur du récepteur décode le signal numérique. Un processeur du récepteur traite les données BLA et/ou ATSC robustes en fonction des informations d'emplacement contenues dans la carte.
