CA 2702054

Provided are a method and apparatus for transmitting broadcast data and a method and apparatus for receiving broadcast data so as to provide a broadcast service. The method of transmitting broadcast data includes: receiving at least one Internet Protocol (IP) packet group, the IP packet group classified based on a service provided by IP packets; generating first mapping information which indicates mapping information between an IP address corresponding to each of the at least one IP packet and an address within a transmission channel on which each of the at least one IP packet group is to be carried; and transmitting the first mapping information and the at least one IP packet group via the transmission channel. A user accesses only desired IP packets quickly and processes them so that a data processing speed can be improved. Image

La présente invention concerne un procédé et appareil pour la transmission de données diffusées et un procédé et appareil pour la réception de données diffusées afin de fournir un service de diffusion. Le procédé de transmission de données diffusées comprend : la réception d'au moins un groupe de paquets de protocole Internet IP, le groupe de paquets IP étant classifié en fonction d'un service assuré par des paquets IP ; la génération d'une première information de mappage qui indique une information de mappage entre une adresse IP correspondant à chaque paquet IP et une adresse dans une voie de transmission sur laquelle chaque groupe de paquet IP doit être transporté ; et la transmission de la première information de mappage et ledit paquet IP via la voie de transmission. Un utilisateur accède uniquement aux paquets IP souhaités rapidement et les traite de sorte qu'une vitesse de traitement de données puisse être améliorée.
