A transport stream provider for providing a plurality of transport stream packets describing digital media information is configured to provide a transport stream packet of a first packet type including a program association table and key information for decrypting encrypted media information. The program association table contains an association between a program No. and a packet type identifier of a further transport stream packet of a second packet type. The transport stream provider is configured to provide a transport stream packet of the second packet type in such a manner that the transport stream packet of the second packet type contains a reference to packet type identifiers of transport stream payload data packets which describe contents of different content types of the digital media information.

A device for controlling a service access authorization for a user device with regard to an access-restricted service includes a service access authorization provider, the service access authorization provider being configured to set a period of time in which the service access authorization is valid, responsive to an authorization message provided with a service-dependent user identifier, and the service access authorization provider being configured to disable an authorization allowing the service access authorization to be extended or reactivated using the previous service-dependent user identifier when at least a predetermined duration has passed since an end of a last authorization time interval for which a service access authorization was determined by the device.

Concept of efficiently distributing access authorization information

In a system comprising a transmitter, a receiver, and a module, a communication object is transmitted from the transmitter to the receiver which comprises a payload data block containing data for generation of a command to the chip module obeying a communication protocol specific for the chip module, and a parameter block comprising at least one instruction which defines how the generation of the command to the chip module is to be performed, thereby facilitating a control and change of the communication protocol between the receiver and the module.
