Abrégé
(EN)
The present invention relates to a method and apparatus for transceiving a broadcast signal. A method for receiving a broadcast signal comprises the following steps: extracting, from the received broadcast signal, a broadcast stream including at least one program, first program table information for indicating the broadcast stream, and second program table information for indicating the correlation among a plurality of programs provided using at least one broadcast service; parsing the broadcast stream using the extracted first program table information; and acquiring, using the extracted second program table information, information on the group to which the plurality of programs belong.

La présente invention porte sur un procédé et un appareil d'émission/réception de signal de diffusion. Un procédé de réception de signal de diffusion comprend les étapes suivantes : extraction, à partir du signal de diffusion reçu, d'un flux de diffusion comprenant au moins un programme, de premières informations de tableau de programme destinées à indiquer le flux de diffusion, et de secondes informations de tableau de programme destinées à indiquer la corrélation entre une pluralité de programmes fournis à l'aide d'au moins un service de diffusion; analyse du flux de diffusion à l'aide des premières informations de tableau de programme extraites; et acquisition, à l'aide des secondes informations de tableau de programme extraites, d'informations sur le groupe auquel appartiennent la pluralité de programmes.
