| description | Provided is a digital radio receiver system and method for switching from receiving a first broadcast service to an alternative broadcast service. Also provided is a digital radio receiver system and method for scanning for broadcast services in a broadcast signal to generate an alternative broadcast service list for use in controlling the digital radio receiver system. A digital radio receiver utilizes spectrum awareness data, which includes data defining one or more frequencies at which broadcast services may be receivable, in order to faster selection of an alternative broadcast service from an alternative broadcast service list containing data relating to alternative broadcast services that are linked by a relationship to other broadcast services. By using the spectrum awareness data, only entries that are considered valid (i.e. entries that are determined to be alternative services that the receiver may receive) are retrieved from the alternative broadcast service list, which reduces the time taken for a receiver to switch to an alternative broadcast service from an initially received broadcast service. |
