Abstract
(EN) A broadcast signal transmission method, according to embodiments of the present invention, comprises the steps of: generating a packet including service data and signaling information for the service data; encoding the packet; and transmitting a broadcast signal including the packet. Moreover, the signaling information includes network information for the broadcast signal, wherein the network information includes first identification information for a main network or an other network, wherein when the first identification information indicates the other network, the network information includes second identification information for an Internet linear channel. In addition, the signaling information is transmitted on the basis of the Internet linear channel, and includes service discovery information for obtaining service data for the Internet channel and uniform resource identifier (URI) information which identifies the service data for the Internet channel.
(FR) L'invention concerne un procédé de transmission de signal de diffusion comprenant les étapes consistant à : générer un paquet comprenant des données de service et des informations de signalisation pour les données de service ; coder le paquet ; et transmettre un signal de diffusion comprenant le paquet. De plus, les informations de signalisation comprennent des informations de réseau pour le signal de diffusion, les informations de réseau comprenant des premières informations d'identification pour un réseau principal ou un autre réseau, lorsque les premières informations d'identification indiquent l'autre réseau, les informations de réseau comprennent des secondes informations d'identification pour un canal linéaire Internet. De plus, les informations de signalisation sont transmises sur la base du canal linéaire Internet, et comprennent des informations de découverte de service pour obtenir des données de service pour le canal Internet et des informations d'identificateur de ressource uniforme (URI) qui identifient les données de service pour le canal Internet.
