Title (EN) METHOD AND APPARATUS FOR PROVIDING BROADCAST SERVICE
(FR) PROCÉDÉ ET APPAREIL DE FOURNITURE DE SERVICE DE DIFFUSION
Abstract:
(EN) A method for providing a broadcast service is provided. The method includes transmitting a user datagram protocol (UDP)/internet protocol (IP) packet including a first message, the first message containing information about a message to be signed and transmitted, and transmitting a moving picture experts group (MPEG) media transport protocol (MMTP) packet including a second message, the second message containing information about the broadcast service and information indicating whether the information about the broadcast service is signed. The first message includes an identifier of a key used to verify a signature of the message to be transmitted and signed and an identifier of a hash algorithm used to calculate a hash value of the message to be transmitted and signed.
(FR) L'invention concerne une méthode pour fournir un service de diffusion Le procédé comprend la transmission d'un paquet de protocole de datagramme utilisateur (UDP)/protocole internet (IP) comprenant un premier message, le premier message contenant des informations concernant un message à signer et transmettre, et la transmission d'un paquet de protocole de transport media (MMTP) de MPEG (Picture Experts Group) comprenant un second message, le second message contenant des informations concernant le service de diffusion et des informations indiquant si les informations concernant le service de diffusion sont signées. Le premier message comprend un identifiant d'une clé utilisée pour vérifier une signature du message à transmettre et à signer et un identifiant d'un algorithme de hachage utilisé pour calculer une valeur de hachage du message à transmettre et à signer.
