Definitions

  • radio transmitters have also transmitted digital data telegrams in accordance with the RDS standard in addition to the radio signals.
  • These data telegrams contain, among other things, identifiers (PS) for the station name, e.g. B. NDR1, NDR3, FFN, ANTENNA and identifiers (PTY) for the program type, eg. B. Sports, news, classic.
  • PS station name
  • PTY identifiers
  • the latter identifier (PTY) is transmitted in each RDS group, i.e.
  • the transmitter identification appears on the display after 1 - 2 seconds at the earliest.
  • a menu mode can be set in the Blau Vietnamese car radio, in which a specific program type is selected and the receivable stations are then searched for in succession, which transmit a program of the selected program type.
  • the selected program type and the channels found are shown in a list below in the header.
  • the invention differs from the prior art by the features listed in the characterizing part of claim 1.
  • FIG. 1 shows a first exemplary embodiment of the invention in block diagram
  • FIG. 2 shows part of a block diagram corresponding to FIG. 1 with a modification corresponding to a second exemplary embodiment of the invention.
  • the digital RDS data telegrams from an RDS radio transmitter reach an RDS radio receiver via the antenna 1 and are separated from the signals of other transmitters in an HF input part 2 with the aid of a tuning part 3.
  • the data telegrams reach an RDS decoder 9 via an IF amplifier 4, which is terminated by an FM detector.
  • the low-frequency sound signals and, if appropriate, the associated stereo signals are further processed in an LF amplifier 5 and reproduced via one or more loudspeakers 6.
  • the tuning part 3 is tuned to the desired transmitter by pressing station buttons 7.
  • the station buttons 7 can optionally comprise several operating levels.
  • a scan processor 8 calls up the individual station buttons 7 one after the other and possibly also detects the individual operating levels.
  • the scan processor 8 can also control a tuning of the entire frequency band according to receivable transmitters. A special feature of the control is given when the scan processor 8 detects the found transmitters after a short playback time of e.g. B. leaves 8 seconds and searches for the next station if the listener does not interrupt this automatic.
  • the circuit connected to the RDS decoder 9 is used for this display.
  • an RDS data processor 10 the many of the above Information transmitted by RDS data telegram, the PTY identifier and the PS identifier are filtered out and the program type of the set station is stored in a memory 11 and the station name of the set station is stored in a memory 12.
  • the outputs of both memories 11, 12 lead to a switch 13, which connects the memory 11 to the input of a display driver 15 in its upper position.
  • the program type is shown on the display 16 via this display driver 15.
  • the program type identifier PTY is available as soon as 80 ms after tuning to the transmitter if reception is undisturbed.
  • the RDS processor 10 requires at least one second for the detection of the transmitter name identifier PS and up to two seconds in the case of error-free reception. Accordingly, group zero must be inserted into the RDS data telegram on the transmitter side.
  • a timer 14 controls the switch 13 into its second position after two seconds after a tuning change, so that the transmitter name is now read out of the memory 12 and shown on the display 16.
  • the timer 14 is of repetitive design, so that the information shown on the display changes again after a further two seconds.
  • Fig. 2 shows a modification of this circuit in the area of the switch 13.
  • the second input of the switch 13 is preceded by an AND stage 13A, so that in this position of the switch 13 both the transmitter name and the program type can also be shown on the display.
  • this presupposes the use of a multi-cell display 16A / B, the rows of which are either arranged one below the other, as shown in FIG. 2, or can also be arranged one behind the other, so that the manner of reading
  • one line i. H. a single information word up to 8 digits.
  • a key can also be provided parallel to the timing element, which switches the switch 13 back to the first position during the actuation of the key, so that the type of program can be displayed again at any time.
  • An alternative to this is to use the button to reset the changeover switch 13 and to trigger the timer 14 again.
  • a color change or a change of contrast in the display 16 can be connected to it.
