Zusammenfassung:The present invention relates to a method of scanning for broadcast services in a broadcast signal to generate a broadcast service list for use with a digital radio receiver system, and the digital radio receiver system used for scanning for broadcast services to generate a broadcast service list. The system utilises spectrum awareness data, which comprises data defining one or more frequencies at which broadcast services may be receivable, in order to reduce the number of frequencies to scan such that the overall scan time may be reduced. The data in the spectrum awareness data is a filtered subset of the plurality of frequencies at which the broadcast services may be received, which allows the controller of a digital radio receiver to tune a tuner to only the frequencies that are likely to contain a broadcast service when generating or updating a broadcast service list.
