A reception device, comprising: a data processing unit configured to receive signaling data including - delivery method information indicating, per file, whether the file is transmitted via broadcasting or via a network, and - class information including a class identifier indicating a group of reception devices or users that are permitted to perform data reception via the network, determine whether a file is delivered via broadcasting or via the network based on the delivery method information, determine whether data reception of said file via the network is permitted for the reception device based on the class information by determining whether or not the class identifier recorded in the signaling data is identical to a class identifier which is assigned to the reception device or the user in advance, and perform data reception of said file - via the network if said file is delivered via the network and data reception of said file via the network is permitted for the reception device, which is the case when the class identifier recorded in the signaling data is identical to the class identifier which is assigned to the reception device or the user in advance, characterized in that the data processing unit is further configured to perform data reception of said file - via broadcasting if said file is not delivered via the network or data reception of said file via the network is not permitted for the reception device, which is the case when the class identifier recorded in the signaling data is not identical to the class identifier which is assigned to the reception device or the user in advance. a data processing unit configured to receive signaling data including - delivery method information indicating, per file, whether the file is transmitted via broadcasting or via a network, and - class information including a class identifier indicating a group of reception devices or users that are permitted to perform data reception via the network, - delivery method information indicating, per file, whether the file is transmitted via broadcasting or via a network, and - class information including a class identifier indicating a group of reception devices or users that are permitted to perform data reception via the network, determine whether a file is delivered via broadcasting or via the network based on the delivery method information, determine whether data reception of said file via the network is permitted for the reception device based on the class information by determining whether or not the class identifier recorded in the signaling data is identical to a class identifier which is assigned to the reception device or the user in advance, and perform data reception of said file - via the network if said file is delivered via the network and data reception of said file via the network is permitted for the reception device, which is the case when the class identifier recorded in the signaling data is identical to the class identifier which is assigned to the reception device or the user in advance, characterized in that the data processing unit is further configured to perform data reception of said file - via broadcasting if said file is not delivered via the network or data reception of said file via the network is not permitted for the reception device, which is the case when the class identifier recorded in the signaling data is not identical to the class identifier which is assigned to the reception device or the user in advance. - via the network if said file is delivered via the network and data reception of said file via the network is permitted for the reception device, which is the case when the class identifier recorded in the signaling data is identical to the class identifier which is assigned to the reception device or the user in advance, characterized in that the data processing unit is further configured to perform data reception of said file - via broadcasting if said file is not delivered via the network or data reception of said file via the network is not permitted for the reception device, which is the case when the class identifier recorded in the signaling data is not identical to the class identifier which is assigned to the reception device or the user in advance.
