[Problem] It is hard to apply the A-VSB transport system to a mobile broadcast. [Solution] Provided are a method and apparatus for transporting a broadcast and a method and apparatus for receiving a broadcast. In the method of transporting a broadcast service for mobile communications, the method includes generating an encapsulation packet including configuration information adaptive to application data that is to be transmitted and the application data; generating transport packets having data regarding the encapsulation packet by dividing the encapsulation packet into predetermined-sized packets, where the transport packets include information regarding the structures of the transport packets; and generating service configuration information including information set about a channel having the transport packets, and including the service configuration information in a service information channel at a predetermined location from among at least one transport channel on a transport stream. Accordingly, it is possible to efficiently use a data region and increase the speed of data transmission.

La présente invention concerne un procédé et un appareil permettant d'appliquer à la diffusion mobile le système de transport A-VSB. À cet effet, l'invention propose, d'une part un procédé et un appareil permettant le transport d'une diffusion, et d'autre part un procédé et un appareil permettant de recevoir une diffusion. Ainsi, le procédé de transport d'un service de diffusion pour communications mobiles consiste à générer un paquet d'encapsulation incluant de l'information de configuration pouvant s'adapter aux données d'application à transmettre ainsi que les données d'application. Le procédé consiste ensuite à générer des paquets de transport comportant des données concernant le paquet d'encapsulation, et ce en divisant le paquet d'encapsulation en paquets de longueur déterminée, les paquets de transport incluant de l'information concernant les structures des paquets de transport. Le procédé consiste enfin à générer une information de configuration de service incluant de l'information définie au sujet d'un canal comportant les paquets de transport, et à intégrer l'information de configuration de service dans un canal d'information de service, en un endroit défini, à partir d'au moins un canal de transport du flux de transport. L'invention permet ainsi d'utiliser de façon efficace une région de données et d'augmenter la vitesse de transmission des données.
