Definitions

  • the invention relates to an RDS receiver and a method for operating a such.
  • the inaudible RDS data stream transmitted in addition to the audible audio signal is demodulated in an RDS demodulator and the various RDS data are made available to the RDS receiver.
  • RDS data include the so-called PI code (Program Identification Code), the PS code (Program Service Name), alternative frequencies and the like.
  • the PS code is in the RDS groups 0A "and 0B "transmitted in pairs.
  • the PS code represents the common name of the received radio program, which is regularly shown on a display of the RDS receiver.
  • the PS code is not being used by an increasing number of radio stations only for the transmission of the program name but also for the use of others Information such as Football results, weather forecasts, traffic jam reports or other comparable data used. With the known RDS receivers, this leads this additional information is shown on the display. The The additional information shown is not specific to the sender and cannot be linked to one specific distinction of the program. As a result, the user loses the opportunity to orientate yourself based on the name of the program and if necessary to choose another station.
  • the object of the invention is to give the user of the RDS receiver the opportunity give the programs despite the transmission of additional information about the PS code to differentiate safely.
  • the received PS code is checked in a correction unit and replaced by a new PS code that one from the RDS receiver or from whose correction unit represents the corrected PS code.
  • This corrected PS code will in the following, as is customary in the prior art, in accordance with the received uncorrected PS code used.
  • the variable and thus not the actual PS code according to circumstances with a new, corrected PS code, the corresponds to the actual circumstances.
  • This new corrected PS code regularly represents the actual program name or at least comes after it to the extent that the user uses the corrected PS code to run the program can differentiate better than with the uncorrected changing PS code.
  • the correction provides various insights into the spelling of real PS codes used to discard and pass through incorrect, incorrect PS codes replace potentially correct PS codes received earlier. Based on such A corrected PS code can be obtained in a fairly secure manner determine.
  • the knowledge is used, that despite the constantly changing PS codes, the program name, which is the desired one Program Service Name represents the most frequently transmitted time.
  • the continuously received PS code is statistically evaluated and the PS code with the maximum frequency as a new, corrected PS code RDS receiver provided for further processing.
  • This will be the Display the new, corrected PS code on a display, for example.
  • This makes it possible, for example, despite short-term transmission of messages in Form of additional information about the PS code such as KSC vs. VFB 5: 2 suppress this representation of the additional information and correct it Name of the program e.g. To display Regnbogn.
  • the correction unit shows a memory in which a table with correct PS codes and various others specific information about the broadcast programs received regardless of the currently received PS code.
  • This Additional information of the program enables a secure assignment a specific PS code, which is the correct PS code of the station currently being received represents, to create and from the tabular assignment of the specific Information on the correct PS code to determine this and the To provide radio receivers as a corrected PS code.
  • specific Information in particular has the frequency, the PI code, possible alternative Frequencies, the identification of the transmitter or the transmitter tower or the EON information highlighted as particularly suitable.
  • the invention also relates to various methods for Operate this RDS receiver. These methods according to the invention show processes and advantages comparable to the advantageous, previously described, RDS receiver according to the invention.
  • FIG. 1 A preferred embodiment of the invention is shown in FIG. 1 and will be described in more detail below.
  • the schematically illustrated RDS radio receiver 1 is included an antenna 2 connected, via which the RDS radio receiver 1 the Receives broadcast signals including the RDS signals.
  • the RDS radio receiver 1 shows a receiving unit 3 which receives the signals received by the antenna 2 processed and the NF signals to the amplifier 4, which passes these signals amplified and the connected speakers 5, of which only exemplary here one is shown, forwards. This describes the signal path of the audio signals.
  • the path of the RDS signals looks different. These signals come from the antenna 2 via the receiving unit 3 to the RDS demodulator 6 which supplies the RDS signals demodulated and the individual RDS data codes selected from the RDS data stream.
  • the PS code is used in particular to represent the program name of the program used in the display 8.
  • other typical uses such as using the PS code with the Structure of tables, for example tables of reception quality of various alternative frequencies of a program.
  • the received and by the RDS demodulator is not 6 demodulated PS code shown in the display 8 or otherwise used, but the corrected PS code formed by the correction unit 7.
  • This PS code is created with the help of various specific information such as the reception frequency of the reception unit 3, the PI code of the received Program, information regarding the EON transmitter used or the transmitted alternative frequencies formed from the RDS data stream. With help one or more of these specific pieces of information is identified in the Correction unit existing memory table, not shown here, the correct PS code determined and supplied to the display 8 as a corrected PS code. So it works distinguishing the programs in a particularly safe and technically simple manner by the user even in the event of a non-specific transmission of changeable PS codes such as soccer scores, weather information and the like guarantee.
  • the individual units of the RDS radio receiver 1 are controlled with a microprocessor, not shown here, which in particular the setting of Receiver unit 3 controls how the display is controlled by the controller.
