摘要： The present invention relates to a digital radio receiver system and method for switching from receiving a first broadcast service to an alternative broadcast service. The present invention also relates to a digital radio receiver system and method for scanning for broadcast services in a broadcast signal to generate an alterative broadcast service list for use in controlling the digital radio receiver system.
A digital radio receiver utilises spectrum awareness data, which comprises 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.

摘要： A broadcast receiver includes a transfer start time calculating unit (131) that calculates a time at which to start the transmission of each file to be received in first reception processing, a switching timing determining unit (132) that determines a switching time at which a switchover from second reception processing to the first reception processing is to be made by a second tuner unit (120, 120'), according to the calculated time at which to start the transmission of each file, and a switching control unit (133, 133') that controls the second tuner unit (120, 120') so that it makes a switchover from the second reception processing to the first reception processing according to the determined switching time. When the second tuner unit (120, 120') makes a switchover from the second reception processing to the first reception processing, a file can be received from its beginning.

摘要： The invention relates to a method for receiving radio broadcast signals by means of a radio broadcast receiver (1) and to a radio broadcast receiver designed accordingly for performing the method, wherein the broadcast receiver (1) has at least two receiving units (2, 3, 4) for different transmission techniques. The user selects a radio broadcast service of a first receiving unit (2) of the at least two receiving units (2, 3, 4), and the selected radio broadcast service is then played back by the radio broadcast receiver (1). Furthermore, according to the invention, the other, second receiving unit (3, 4) for the different transmission technique of the radio broadcast receiver (1) searches for an alternative radio broadcast service having preferably the same or comparable content during the playback of the radio broadcast service selected by the user, and the radio broadcast receiver (1) automatically switches over to the second receiving unit (3, 4) having the alternative radio broadcast service if the first receiving unit (2) cannot play back the selected radio broadcast service.
