Abstract

L'invention concerne un appareil de communication (100) qui transmet un contenu vidéo, qui comprend une indication vidéo et non vidéo, telle qu'un sous-titre, à un dispositif externe (200) ayant une unité d'affichage (210). L'appareil de communication (100) génère, sur la base d'informations d'instruction qui ont été reçues en provenance du dispositif externe (200) et qui sont associées à une position d'affichage, des données vidéo à utiliser pour afficher le contenu vidéo sur l'unité d'affichage (210), et transmet les données vidéo générées au dispositif externe (200). Si les informations d'instruction sont associées à l'indication non vidéo, l'appareil de communication (100) génère des données vidéo de telle sorte que l'indication non vidéo sera affichée conformément à l'instruction.
