Abstract

La présente demande concerne un système de publication de contenu vidéo, qui peut réduire la charge imposée à un récepteur de télévision qui reçoit des métadonnées, telles que des informations de programme publiées dans une communication radiodiffusée. Le système de publication de contenu vidéo comprend : un système de publication, qui publie un contenu vidéo et des métadonnées ; un serveur partagé intermédiaire, qui reçoit et accumule les métadonnées pour sélectionner un contenu vidéo, et effectue une conversion et un envoi ; un serveur de transmission, qui reçoit les métadonnées délivrées par le serveur partagé intermédiaire, convertit une pluralité de vignettes en une image intégrée, effectue une conversion de format de transmission sur l'image intégrée, et envoie les métadonnées ; et un récepteur de télévision, qui reçoit le contenu vidéo en provenance du système de publication et reçoit les métadonnées en provenance du serveur de transmission. Un système d'exploitation de télévision reçoit les métadonnées et affiche une image, de sorte qu'un contenu vidéo basé sur la communication puisse être facilement sélectionné.
