Definitions

  • the invention relates to a radio receiver with an LF amplifier and with at least one traffic radio decoder for received traffic information according to the preamble of claim 1.
  • a 57 kHz carrier is provided for the station identification, which serves to identify all traffic radio stations.
  • the 57 kHz carrier is modulated with one of six possible range frequencies (letters A-F). In this way, an identification is made of the traffic radio area to which the relevant traffic radio station belongs.
  • a second modulation of 125 Hz on the 57 kHz carrier is used as the announcement identifier during a traffic announcement to identify the relevant traffic information.
  • a special decoder is required within the radio receiver for the evaluation and processing of the three identifiers or characteristic frequencies mentioned, and the known system advantageously allows the construction of very inexpensive traffic radio decoders which are able to give the driver the ver inevitably bring sweeping instructions to your hearing.
  • An additional receiver in the car radio searches for the responsible traffic radio station using the transmitter and area identification. By evaluating the announcement identifier, the driver is given the traffic information acoustically even if he hears another program or music from a cassette, for example.
  • a traffic radio decoder for processing digital signals has therefore already been described, the digital signals identifying the traffic information, and the digital signals being obtained by demodulating an auxiliary carrier on which the digital signals are modulated (magazine "Internationales Verledgement”; Special print from issue 5/85; Peter Brägas “Control and information systems in motor vehicles - a contribution to the improvement of traffic flow and traffic safety", pages 2 - 8).
  • the RDS system is intended for the transmission of digital signals on a subcarrier of 57 kHz via VHF radio transmitter, with a double sideband amplitude modulation of the 57 kHz carrier (carrier is suppressed) with the biphase-coded data signal. Due to the biphase coding, no spectral lines appear in the vicinity of the carrier, so that there is compatibility with the other system, which can thereby be further developed in an advantageous manner.
  • the basic idea behind the alternative of the RDS system is to transmit digital memory addresses or code words, the components of structures of traffic information being stored in the radio receiver or in the traffic radio decoder under the respective addresses and ready for display and for display playback using a speech synthesizer.
  • the focus is therefore not on sending a traffic announcement, but on the transmission of digital signals which represent certain traffic announcements, so that in addition to the RDS system, other digital transmission systems can also be considered in principle.
  • the RDS system is only at the beginning of a technically practical introduction, while - as already mentioned above - the first system has been in use for a long time. Since the RDS system has not yet been introduced correctly, and since the first system will not be replaced overnight, but rather will still be used during a long transition phase, the problem with the already existing and also with the newly manufactured radio devices is that the Users can receive only traffic messages from the first system or only RDS traffic messages.
  • the object of the invention is to create a radio receiver to avoid the disadvantages described, which enables the listener to receive all traffic reports, in particular during the transition phase to the RDS system.
  • the invention is based on the fact that, in addition to the new RDS system, the tried-and-tested other system will continue to be used during a long transition phase, and that in certain areas only this system will still be used. Nevertheless, the traffic reports and the traffic information should reach the listener regardless of the type of system, even if the respective traffic information is broadcast in parallel according to the first system and the RDS system.
  • both a traffic radio decoder of the first system and an RDS traffic radio decoder is provided in the radio device according to the invention, and that either either the traffic radio decoder of the first system or the RDS traffic radio decoder by means of a selector switch to the Amplifier of the radio receiver can be switched through, it is ensured that, given the parallelism of both systems, the radio receiver can still be used universally.
  • the selector switch ensures that traffic information received according to the first system on the one hand and the RDS system on the other hand is not heard in parallel, which would completely confuse the driver. Rather, it is ensured that only the traffic announcement of the first system or the RDS traffic announcement is brought to the listener or the driver. Since the radio receiver can receive both systems, it is ensured during the transition phase that no traffic information is lost.
  • This solution is also particularly advantageous because the traffic information can be saved using the RDS system. It is therefore possible to first reproduce the traffic information of the first system acoustically, and then, if necessary, the parallel RDS traffic information can then also be called up from the memory and played back via a speech synthesizer.
  • the radio receiver designated as a whole by the reference number 10, has a receiving antenna 12 for receiving the programs broadcast by a traffic radio station or also by another station.
  • the radio receiver 10 comprises a mixer stage 14 which is controlled by an oscillator 16 and to which an IF amplifier 18 and a demodulator 20 are connected.
  • the demodulator 20 is connected via a volume control 34 to an LF output stage 36, via whose loudspeaker 38 the demodulated signals can be reproduced.
  • the radio receiver described so far is known per se.
  • a first traffic radio decoder 22 is connected to the demodulator 20, the output of which leads to a switching stage 24.
  • the switch of the switching stage 24 is closed, while the program just heard via the loudspeaker 38 is interrupted by the transmitter. After the traffic announcement has ended, the system automatically switches back to the current radio program.
  • the switching stage 24 therefore interacts with a selector switch 26 which has three switch positions and can therefore connect the volume control 34 to three different contacts.
  • the demodulated radio signal reaches the LF output stage 36 via the volume control 34.
  • the middle switch position of the selector switch 26 only a traffic announcement from the first traffic decoder 22 is heard.
  • the output of the demodulator 20 leads to an RDS traffic radio decoder 28, which is followed by a memory 30.
  • a memory synthesizer 32 follows the memory 30, whose output is connected to the lower contact pole of the selector switch 26, so that in the lower switch position of the selector switch 26 the speech synthesizer 32 is connected to the LF output stage 36 via the volume control 34.
  • the new radio receiver 10 is additionally provided with an RDS traffic radio decoder 28 in addition to the first traffic radio decoder 22, it is possible with the aid of the selector switch 26 to send either the first traffic radio decoder 22 or the RDS traffic radio decoder 28 to the To switch on the NF output stage 36, in the latter case the synthetic speech of the RDS traffic radio decoder 28 is reproduced via the speech synthesizer 32.
  • the user or the driver can be brought to listen to the traffic announcement that is currently being received with the aid of the automatically controllable selector switch 26, it then being immaterial whether the traffic announcement is transmitted according to the first system or according to the RDS system and Will be received. It is thus ensured that all traffic messages em during a transition phase in which both systems coexist can be caught.
  • the first traffic radio decoder 22 is primarily connected to the LF output stage 36.
  • the RDS traffic information received simultaneously from the RDS traffic radio decoder 28 initially remains in the memory 30 and is only switched to the LF output stage 36 after the traffic information has ended, so that the traffic information is only then reproduced via the speech synthesizer 32.
  • the LF output stage 36 is connected here to the volume control 34 via a decoupling resistor 40.
  • the last-described operating mode with simultaneous presence of both a first traffic notice and an RDS traffic notice is indicated in FIG. 2 by the dashed lines 46.
  • the switches 42 and 44 are open, so that the em p Huaweie radio program and the speech synthesizer 32 are switched off by the LF power amplifier 36.
  • switch 42 In the case of a subsequent transmission of a normal radio program, switch 42 according to FIG. 2 is closed, while switches 24 and 44 are open. When an RDS traffic information is transmitted, only switch 44 is closed, while switches 42 and 24 are open. It is possible to route a stored RDS traffic message to the LF output stage 36 via the speech synthesizer 32 and to make it audible via the loudspeaker 38.
