  • the third NAL-unit is of type 6, which means that the payload contains additional information.
  • This NAL-unit does not contain data about the pixels.
  • a legacy decoder comprised in an STB will recognize that the payload type is equal to 6 and will ignore it, so it should not impose any problems to a legacy STB.
  • an STB according to this disclosure will parse the payload and will detect that it comprises meta data. The STB will further store the meta data internally or externally and will upon request retrieve a code from it. The retrieved code is then sent to be displayed on the screen.

Abstract

La présente invention concerne un procédé et un nœud de réseau (12, 20) permettant d'afficher un code sur un écran (14) faisant appel à la réception, d'un nœud opérateur (10) compris dans le réseau d'opérateurs (22), d'un flux de données comprenant des données et des métadonnées, et à l'extraction des données et des métadonnées du flux de données reçu. Selon l'invention, le nœud de réseau envoie les données extraites à afficher sur l'écran et mémorise les métadonnées. Lors de la réception d'une requête sur le code d'un dispositif de communication configuré au préalable (16), le nœud de réseau récupère alors un code généré à partir des métadonnées mémorisées et envoie le code pour affichage sur l'écran.
