Abrégé
(EN) A multicast transmission method for OTT media comprises: a terminal sends request media description information corresponding to OTT media to a multicast server; the terminal receives media description information fed back by the multicast server for the request media description information, the media description information comprising multicast information, and the multicast information comprising multicast group information; and the terminal receives, according to the multicast group information, a multicast data packet sent by the multicast server, the multicast data packet being generated by encapsulation of a media index file corresponding to the request media description information and/or a media content file corresponding to the request media description information.
(FR) L’invention concerne un procédé de transmission en multidiffusion de contenu multimédia OTT comprenant les étapes suivantes : un terminal envoie à un serveur de multidiffusion une demande d’informations de description multimédia correspondant à un contenu multimédia OTT ; le terminal reçoit des informations de description multimédia retournées par le serveur de multidiffusion en réponse à la demande d’informations de description multimédia, les informations de description multimédia comprenant des informations de multidiffusion comprenant des informations de groupe de multidiffusion ; et le terminal reçoit, selon les informations de groupe de multidiffusion, un paquet de données de multidiffusion envoyé par le serveur de multidiffusion, le paquet de données de multidiffusion étant généré en encapsulant un fichier d'index multimédia correspondant à la demande d’informations de description multimédia et/ou un fichier de contenu multimédia correspondant à la demande d’informations de description multimédia.
