Abstract:
In digital broadcast systems, it is common to broadcast besides main services additional services like news services. Typically, these additional services are regularly updated and broadcasted by a service provider (3) several times a day. In order to keep service data transmitted by the additional services up to date in a receiving device (1) receiving the services, a method of accessing services is given according to which a respective service information about the services provided by service providers (3) is extracted from a service presently received by the receiving device (1), and then at least one of the services about which service information was extracted according to the respective extracted service information might be accessed. Thus, the service data can automatically be updated by the receiving device (1) itself, even if transmission conditions of an additional service like update rates change over the time.
