Abstract: The present invention provides for an analog and/or digital radio broadcast transmission system and radio receiver therefor, which includes a control signal having an item of control information concerning another, different type of transmission/receive system. The receiver is a hybrid receiver able to receive both types of signals. When the same program material is available on both of the different systems, the control signal is used for switching the different systems so that the receiver receives the program on the system which provides the best reception.

Abstract: A VHF radio receiver intended for mobile use, e.g. in a car, features inputs from multiple antennas. Each antenna signal is mixed with a locally-generated oscillator signal; the resulting mixed signals are added, with controllable phase position, to form a summation signal. Alternate frequencies, as defined by the Radio Data System (RDS) international standard, are stored. At periodic time intervals, momentary switchover is made to alternate frequencies to measure their reception quality and to store this parameter. Whenever the originally-tuned frequency provides inadequate reception quality, a control circuit 19 switches over to the best of the alternate frequencies, so quickly that the changeover is almost imperceptible to the listener.

Abstract: Systems and methods for aiding user content navigation are described. An exemplary system may include an electronic device configured to receive audiovisual content and/or user inputs. The electronic device may additionally include one or more outputs coupled with a display device. The electronic device may further include one or more processors as well as memory, which when executed by the one or more processors, cause them to perform one or more navigation functions to receive a channel change command to adjust from a first channel to a second channel. The one or more processors may further be caused to determine that the second channel is presenting advertising content instead of program content, and determine that a third channel is presenting program content. The one or more processors may further be caused to adjust the output to the third channel.

Abstract: 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.

Abstract: A vehicle and a method for controlling the same are provided. In particular, linking information of a broadcast signal having been output during a turn-off mode is transmitted to a DAB receiver upon receiving a turn-on signal. The vehicle includes a Digital Audio Broadcasting (DAB) receiver that is configured to receive a first DAB signal that corresponds to a selected first broadcast signal. In addition, a speaker outputs the first broadcast signal based on the received first DAB signal or a first frequency-modulation (FM) signal corresponding to the first broadcast signal. In response to receiving a turn-on signal, a controller transmits linking information of the first broadcast signal from among linking information of a plurality of broadcast signals to the DAB receiver to output the first broadcast signal output during a turn-off mode.
