Abstract

La présente demande concerne un système de publication de vidéo, un téléviseur, un procédé de publication de vidéo et une passerelle de télévision. Lorsque le contenu vidéo transmis au moyen d'une onde de diffusion est commuté vers un contenu vidéo publié au moyen d'un réseau, l'opération de commutation peut être réalisée facilement sans provoquer de gêne pour les utilisateurs et les téléspectateurs en raison de différences dans des services de transmission et de publication de contenu. Dans le téléviseur, lorsque le contenu vidéo transmis au moyen de l'onde de diffusion ne peut pas être reçu, il est commuté vers le contenu vidéo publié au moyen du réseau. Au moyen de métadonnées fournies par la passerelle de télévision, une fonctionnalité de visualisation à région limitée est fournie; en outre, la commutation est automatisée au moyen de la détermination de l'intensité de champ électrique de l'onde de diffusion. De plus, un contrat de réception dans la diffusion est automatiquement hérité d'une publication basée sur un réseau, de telle sorte que l'opération de commutation peut être réalisée facilement sans provoquer de gêne pour les téléspectateurs.
