Abstract

La présente invention concerne un procédé, un équipement corrélatif et un système d'accès par un terminal de télévision numérique à la vidéo sur Internet. Le procédé d'accès par un terminal de télévision numérique à la vidéo sur Internet consiste en ce qui suit : une adresse URL (Universal Resource Locator) envoyée par un système de guide électronique des programmes interactif (iEPG) est reçue par un gestionnaire de flux vidéo sur Internet, et l'adresse URL correspond à une vidéo sur Internet ; on juge alors si c'est la première fois que l'adresse URL est reçue ; si c'est la première fois que l'adresse URL est reçue, alors un transcodeur vidéo et un système de réseau de distribution multimédia (MDN) sont notifiés d'exécuter des opérations correspondantes, et une adresse URL de protocole RTSP (Real Time Streaming Protocol) correspondant à l'adresse URL est générée ; l'adresse URL RTSP est envoyée au système iEPG de telle sorte que l'adresse URL RTSP peut être renvoyée à un terminal de télévision numérique par le système iEPG, et le flux vidéo enregistré par le système MDN devient accessible, selon l'adresse URL RTSP, par le terminal de télévision numérique. La solution de la présente invention permet de résoudre efficacement le problème selon lequel un terminal de télévision numérique traditionnel ne peut pas accéder à la vidéo sur Internet.
