Abstract
(EN)  A content transmission method capable of transmitting content by using a broadcast wave and a communication channel, the content transmission method including an information transmission step for transmitting, when transmitting content using each of the broadcast wave and the communication channel, information for synchronizing content obtained by the broadcast wave and content obtained by the communication channel when received by a receiving side, and pertaining to content transmitted by the communication channel, by using at least the broadcast wave among the broadcast wave and the communication channel, the information being included in application control information when transmitted. The present invention thereby provides a content transmission method for enabling quick access to content obtained by communication when content using broadcast and communication together is reproduced on the receiving side.
(FR)  Procédé de transmission de contenu à l'aide d'une onde de diffusion et d'un canal de communication. Ce procédé de transmission de contenu comprend une étape de transmission de l'information. Lorsque le contenu est transmis à la fois par l'onde de diffusion et le canal de communication, il comprend également des informations de synchronisation du contenu obtenu par l'onde de diffusion et du contenu obtenu par le canal de transmission lors de la réception du côté réception. En fonction du contenu transmis par le canal de communication, le procédé utilise au moins l'onde de diffusion sur les deux voies de transmission (onde de diffusion et canal de communication), l'information étant incluse dans les informations de commande de l'application lors de la transmission. Ainsi, la présente invention offre un procédé de transmission de contenu permettant d'accéder rapidement au contenu obtenu par la communication lorsque le contenu, utilisant à la fois la diffusion et la communication, est reproduit du côté réception.
