Abstract:
(EN) The present invention effectively enables clock synchronization and presentation synchronization in a case where media transmission packets obtained by fragmenting video, audio, or other media for transmission are transmitted via a broadcast signal. A 27 MHz clock synchronized with time information obtained from a time information server is generated. Time information that includes frequency information for the 27 MHz clock and is synchronized with the time information obtained from the time information server is generated. Media for transmission is encoded. The encoded media for transmission is fragmented into prescribed units, and media transmission packets including each fragment are generated. A stream including, in a time-division manner, the media transmission packets, packets having the time information, and packets having a control signal are transmitted via broadcast waves.
(FR) La présente invention réalise efficacement un synchronisation d'horloge et une synchronisation de présentation dans un cas où des paquets de transmission de contenu multimédia obtenus par fragmentation de vidéo, d'audio ou d'autre contenu multimédia pour une transmission sont transmis par l'intermédiaire d'un signal de diffusion. Une horloge à 27 MHz synchronisée avec des informations de temps obtenues à partir d'un serveur d'informations de temps est générée. Des informations de temps qui comprennent des informations de fréquence pour l'horloge à 27 MHz et sont synchronisées avec les informations de temps obtenues à partir du serveur d'informations de temps sont générées. Un contenu multimédia pour une transmission est encodé. Le contenu multimédia encodé pour une transmission est fragmenté en unités prescrites, et des paquets de transmission de contenu multimédia comprenant chaque fragment sont générés. Un flux comprenant, dans une manière à division temporelle, les paquets de transmission de contenu multimédia, des paquets ayant les informations de temps, et des paquets ayant un signal de commande sont transmis par l'intermédiaire d'ondes de diffusion.
