    Abstract: For the purpose of transmitting digital audio signals from recording studios to the various broadcasting stations of a broadcasting network, the data flow of the digital audio signals to be transmitted is initially reduced in accordance with a technique which utilizes the psychoacoustic phenomena of the human ear. Then groups of these data-reduced digital audio signals are respectively encoded in a baseband in accordance with a DS1-technique and combined to form respective DS1/M-signals. Finally, the thus produced DS1/M-signals are transmitted in accordance with the DSR technique by use of a wide-band transmission system to the individual broadcasting stations of the broadcasting network.

    Abstract: A receiver, adapted to the reception of identification data in accordance with the RADIO DATA system (RDS) and having only one tuner, effects the acquisition of the identification code of an alternative channel by sampling the alternative channel during periods in which the audio output of the receiver is muted. These periods are of such a short duration that they are not noticed by the listener.

    Abstract: In the evaluation of traffic announcements received in digitally encoded form in a data packet, the data packet is decoded continuously, and the traffic announcements are stored in memory after the decoding and evaluation. A computer in the receiver must evaluate the incoming data stream continuously. Since evaluation is difficult, particularly under unfavorable broadcasting conditions in which error corrections may be necessary, the computer would have to have a very complex program structure and configuration. To make it possible to use a simpler computer configuration and program structure, one complete cycle of traffic announcements is first decoded, optionally error corrected and stored in memory. Next, an updating bit present in the data packet and altered upon any change in the traffic announcements, is identified and evaluated. As a fuction of this evaluation, a further complete cycle of traffic announcements is decoded and stored in memory only if the updating bit has altered.

    Abstract: A demodulator for biphase, suppressed-carrier PSK signals, in particular useful for the demodulation of digital information transmitted as an auxiliary information in radio transmission channels, in particular of the "radiodata" kind comprising a filter for the extraction of the portion of the base band spectrum carrying said PSK signals, an amplitude limiter connected to the output of said filter for standardizing the amplitude of said PSK signals, a double-loop circuit receiving the limiter signal comprising a first loop associated with a data transition tracking loop decoder; a second loop constituted by a digital phase-locked loop. The double loop circuit cooperates with a stable oscillator for providing a frequency at a predetermined multiple of the frequency of the suppressed carrier of said PSK signal from the limiter signal.

    Abstract: In a vehicular radio receiver having a decoder for decoding digitally encoded received traffic announcements, a memory device for route-specific characteristics and a visual and/or acoustical output device for the traffic announcements are provided. The output is effected by the readout of information from the memory device. To output not only factual information but detour recommendations as well, place names and detour route names are stored in the memory device in jointly addressable memory fields. In transmitting the encoded traffic announcements it is then possible to allow or suppress the output of the already stored detour recommendations only on the basis of a control signal.

    Abstract: Disclosed is an electronic device including a communication module, a processor and a memory that stores instructions. The instructions, when executed, cause the processor to receive a first signal from a first external electronic device through the communication module while a communication connection to at least one second external electronic device is being established, select a specified number of third external electronic devices or less from among the first external electronic device and the at least one second external electronic device based on the first signal, and transmit data to or receive data from the selected third external electronic devices through established communication connections to the selected third external electronic devices. The third external electronic devices are selected in order of having a weak signal intensity or a greater distance from the electronic device from among the first external electronic device and the at least one second external electronic device.

    Abstract: Implementing and applying a database with radio station information that is gathered from client devices as stations become available to a plurality of users (i.e., “crowd sourced” radio station information) and allowing for a client device to download only the radio station information that is pertinent to the travel route of the user and/or radio station selection criteria associated with the client device or the user. Radio station information can be rendered via a graphical interface of a client device to allow the user to informatively select a new radio station, either before or as a current radio signal degrades to the point of being unusable. Radio station information may be rendered to cause the user's terrestrial radio to tune to a new station.
