The invention relates to a method for receiving radio broadcast signals by means of a radio broadcast receiver and to a radio broadcast receiver designed for performing the method, wherein the broadcast receiver has at least two receiving units for different transmission techniques. The user selects a radio broadcast service of a first receiving unit of the at least two receiving units, and the selected radio broadcast service is then played back by the radio broadcast receiver. The other, second receiving unit for the different transmission technique of the radio broadcast receiver 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 automatically switches over to the second receiving unit having the alternative radio broadcast service if the first receiving unit cannot play back the selected radio broadcast service.

A digital broadcast receiver includes a first receiving module tunable to a foreground broadcast service to extract a program information, a first decoder module coupled to the first receiving module and decoding the program information, an output module switchably coupled to the first decoder module and adapted to output the program information, at least one second decoder module coupled to the first receiving module and tunable to a background broadcast service to decode a program information associated with the background broadcast service, and a control unit adapted to tune the first receiving module and the first decoder module to the foreground broadcast service and to tune each of the at least one second decoder modules to a background broadcast service. The control unit determines the foreground broadcast service based on a user input and determines the background broadcast services based on the foreground broadcast service and a predefined rule.

In one example, a system includes: a circuit board; at least one tuner adapted on the circuit board to receive and process a radio frequency (RF) signal to output a downconverted modulated signal; a processor adapted on the circuit board to demodulate the downconverted modulated signal, process the demodulated downconverted signal and output an audio signal; a location on the circuit board to receive a demodulator circuit; and a shunt element adapted on the circuit board to direct the downconverted modulated signal from the at least one tuner to the processor when the system does not include the demodulator circuit.

A receiver and associated methods are described. The receiver comprises a first oscillator 14, a second oscillator 16, a controller 18 operable to control frequencies to which the first and second oscillators are tuned, and a discrimination circuit 24 operable to receive and monitor transmitted signals; wherein the discrimination circuit is configured to receive a signal at a first transmission frequency determined based on a first tuned frequency to which the first oscillator is tuned, and to determine, in a capture time period, whether data is being transmitted at the first transmission frequency; wherein the controller is configured to tune, in a tuning time period, the second oscillator to a second tuned frequency; and wherein the tuning time period is shorter than the capture time period.

A broadcast receiving system capable of receiving mobile broadcast data and a method for processing broadcast signals are disclosed. The broadcast receiving system includes N number of antenna elements, a demodulator, a transmission parameter detector, and a block decoder. The N number of antenna elements receives each of the broadcast signals. The demodulator demodulates the broadcast signal having greater signal strength among each of the received broadcast signals. The transmission parameter detector detects the transmission parameter. The block decoder symbol-decodes the mobile broadcast service data included in the received broadcast signal in block units, based upon the detected transmission parameter.

A method for scanning a frequency band for producing a service plan. The method parallelises the scanning by dividing the analysis into two steps: an exploration step for the purpose of detecting channels or frequencies carrying services; and an analysis step for extracting detected channels from program information in order to supply a service plan. Each of the steps is performed by multiple task instances. These tasks share the band to be explored and synchronise, for one same step, via semaphores and, for an inter-step communication, according to a producer/consumer principle.

When the reception level of a main tuner (3) is equal to or lower than a first threshold or the reception level of a sub tuner (4) is equal to or lower than a second threshold while the sub tuner (4) performs data service reception, a sub tuner processing control unit (90), a broadcast program search control unit (91), and a data service control unit (93) cause the sub tuner (4) to suspend the running data service reception and start a broadcast program search. Then, while the reception level of the main tuner (3) is equal to or lower than the first threshold or the reception level of the sub tuner (4) is equal to or lower than the second threshold, the sub tuner processing control unit (90) and the broadcast program search control unit (91) cause the sub tuner (4) to repeatedly and continuously perform a broadcast program search.

The present disclosure relates to a method and system for receiving a broadcast signal. The system includes a broadcast receiver device having two receiving units, two decoding units, a combining unit and a further processing unit. A broadcast signal is received by both receiving units, so that two reception signals are provided. From each reception signal, a raw data stream is extracted and decoded by the decoding units. It is checked if the data stream provided by each decoding unit is complete. If a first data stream is complete, it is processed by the further processing unit. If the first data stream is incomplete and the second data stream is complete, the second data stream is further processed. If both data streams are incomplete, they will be combined to a combined data stream by the combining unit, the combined data stream being further processed, if it is complete.
