Definitions

  • the invention relates to a method for receiving and outputting a broadcast program with added digital information according to the preamble of independent claim 1.
  • RDS radio data system
  • the broadcast program and the digital information are received and output by a broadcast receiver according to the preamble of independent claim 12.
  • This is for example Franz Stollenberg, "RDS - a new service in FM broadcasting", NTZ, Volume 40, 1987, Issue 5, page 346 ff , described.
  • the radio data system is a data channel with which additional and inaudible digital data is transmitted in parallel to the broadcast program.
  • Broadcast receivers with appropriate RDS decoders record RDS data transmitted in addition to broadcast reception with the same receiving section, decrypt RDS data and reproduce it.
  • Over the RDS data channel information such as e.g. Traffic messages, transmitted by code words, with the location of the event and the event itself be transmitted. Instead of traffic reports, other RDS payloads of any kind such as e.g. Event notes are transmitted.
  • the RDS data received includes, in addition to the RDS payload, a program identifier identifying the sender of the RDS data, and a program service name representing the sender of the RDS data.
  • DAB digital broadcasting
  • the inventive method with the features of independent claim 1 and the radio receiver with the features of independent claim 8 have the advantage that digital information of any station regardless of the set radio station whose broadcast program is heard, are issued. In this way, regardless of the broadcast program selected, digital information of another station can be output at a selected station for the broadcast program. This makes the output of broadcast programs and digital information more flexible.
  • the listener is thus not limited to the information of the radio program. This is particularly advantageous in a multi-tuner concept in which a first tuner receives the broadcast program and a second tuner receives the digital information.
  • DAB digital broadcasting
  • RDS radio data signal
  • An advantage of the method according to the invention is to use RDS data of a radio data signal as digital information and to output a designation for the transmitter of the RDS data in addition to RDS user data. This ensures that the listener gets the information from which station the output RDS payload data is sent. Thus, the output RDS payload data can be uniquely assigned to a sender.
  • a further advantageous embodiment of the method according to the invention is achieved in that together with the RDS data, the program identifier of the transmitter of the RDS data is stored. In this way, a simple and secure allocation of the received RDS data to the transmitter of the RDS data is possible.
  • a further advantageous embodiment of the method according to the invention is to use a table which contains a direct assignment of the program identifier to the name, in particular the program service name, of the transmitter of the RDS data.
  • the name of a transmitter can be read out in a simple manner via the program identifier.
  • a simple distinction between the program service name of the broadcast program and the program service name of the RDS data is achieved in that the program service name of the transmitter of the RDS data is carried out by means of an acoustic output or on a display in striking shape, such as is displayed as a marquee and / or flashing and / or in inverse representation and / or in a striking color.
  • Figure 1 shows schematically a radio receiver with two tuners.
  • An antenna 6 is connected via a first antenna line 11 to an input of the first tuner 1, which represents a first receiving part.
  • the first tuner 1 is connected via a second antenna line 12 to an input of the second tuner 2, which constitutes a second receiving part.
  • the second tuner 2 is connected to a microprocessor 3 via a second output line 13.
  • the first tuner 1 is connected to the microprocessor 3 via a first output line 14.
  • the microprocessor 3 is connected to an input unit 10 via a first data line 15. Furthermore, the microprocessor 3 is connected via a second data line 16 with an optical display unit 9, a third data line 17 with a first memory 4, with a fourth data line 18 with a second memory 5 and with a fifth data line 19 with a speech synthesizer 7.
  • the speech synthesizer 7 is connected to a loudspeaker 8 via a sixth data line 20.
  • the microprocessor 3 is connected via an audio line 21 to the speaker 8.
  • the arrangement according to FIG. 1 functions as follows: A received signal from the first tuner 1 is received via the antenna 6.
  • the first tuner 1 is set to a transmitter and transmits its broadcast program to the microprocessor 3 on.
  • the microprocessor 3 outputs the received broadcast program as an audio signal via the audio line 21 and the speaker 8.
  • the reception signal is made available to the second tuner 2 via the first tuner 1.
  • the second tuner 2 is set to a second transmitter and receives RDS data and passes them to the microprocessor 3 on.
  • the microprocessor 3 determines from the supplied RDS data the RDS payload data, e.g. Traffic information, the program identifier and the program service name.
  • the microprocessor 3 stores the RDS payload data, and the program identifier of the RDS data in the second memory 5.
  • the microprocessor 3 stores the program identifier and the program service name of the RDS data in the form of a table in the first memory 4, if the program identifier and the program service name have not yet been stored in the first memory 4.
  • the table provides a direct mapping between the program identifier and the program service name.
  • the second tuner 2 may advantageously also receive additional digital information of a digital broadcast program and from the additional information payload data, such as e.g. Determine traffic messages and a name for the transmitter of the additional information according to the method described.
  • additional information payload data such as e.g. Determine traffic messages and a name for the transmitter of the additional information according to the method described.
  • the user data and the designation are output independently of the broadcast program output in accordance with the described method.
  • the output of the broadcast program (audio signal) is independent of the reception of the RDS data by the second tuner 2
  • the second tuner 2 searches for RDS data at different reception frequencies, so that the microprocessor 3 receives the RDS data different program service provider in the second memory 5 stores.
  • the microprocessor 3 outputs the currently received RDS data optically via the display unit 9 or acoustically via the speech synthesizer 7 and the loudspeaker 8.
  • the microprocessor 3 outputs the program service name acoustically or optically in parallel with the RDS data.
  • the presentation of the program service name of the provider of the RDS data takes place advantageously in the form of a marquee and / or or flashing and / or inverse and / or conspicuous colors different from other representations of the optical display unit 9.
  • the table is stored, which allows a direct assignment of the program identifier to the program service name. In this way it is possible for the microprocessor 3 to determine the program service name of the provider of the RDS data via the program identifier for the received RDS data. This offers the advantage that the program service name must be determined only once from the RDS data, which is relatively expensive.
  • the output of the RDS user data is carried out according to a development of the method according to the invention after an input, which takes place via the input unit 10.
  • a key of the input unit 10 is pressed and thus causes the output of the RDS user data.
  • the method of the invention especially for the issue of traffic messages ("Traffic Massage channel”), which are collected and then output on input.
  • FIG. 2 shows a schematic program sequence for carrying out the method according to the invention.
  • the first tuner 1 receives at a predetermined reception frequency a broadcast program (audio signals) output via the microprocessor 3 and the speaker 8.
  • the second tuner 2 receives the RDS data of a transmitter.
  • the transmitter or program provider of the RDS data can - but need not - match the transmitter that the first tuner 1 receives.
  • the RDS data is passed to the microprocessor 3.
  • the microprocessor 3 stores the RDS payload and the program identifier of the RDS data in the second memory 5.
  • the microprocessor 3 checks at program point 32 whether the received RDS user data match already stored in the second memory 5 RDS user data. If the received RDS user data is new, the microprocessor 3 searches the program identifier of the newly received RDS data at program point 33 in the table which is stored in the first memory 4.
  • the program identifier of the newly received RDS data has not yet been stored in the first memory 4
  • the program identifier and the program service name are now first stored by the microprocessor 3 in the first memory 4 in the table.
  • the microprocessor 3 must determine the program service name from the RDS data.
  • the program service name is then read from the table and output with the RDS user data at program point 33. Afterwards, branch back to program point 30.
  • the query at program point 32 indicates that the RDS payload is not new, i. that both the RDS user data and the program identifier and the program service name are already stored, the query is made at program point 34, whether a manual operation via the input unit 10 is done. If this is the case, then at program point 35 the stored RDS user data are output with the respective program service name. Afterwards, branch back to program point 30. If the query at program point 34 shows that no input has occurred, then the program branches back to point 30.
  • the output of the program service name is advantageously carried out either before the output of the traffic reports or after the output of the traffic reports via the speaker.
  • the program service name can be output visually via the optical display unit 9 parallel to the acoustic output of the traffic reports. If the traffic reports are output via the optical display unit 9, the program service name is also output via the optical display unit 9 either before or after the output of the traffic reports. As the output device, the optical display unit 9 and the speakers 8 are used.
  • the program service name is conspicuously displayed in the optical output so as to be different from other representations of the optical display unit 9. This is done e.g. in the form of a marquee or flashing and / or inverse and / or in a distinctive color, which differs from the colors of the other representations of the optical display unit 9.
  • the program identifier of the transmitter is stored, from which the traffic message was first received.
  • An additional advantageous embodiment of the method according to the invention is to store the program identifier of the transmitter from which the traffic message was last received.
  • inventive method and the radio receiver according to the invention have been described by way of example for a broadcast program with a radio data signal.
  • the inventive method and the radio receiver according to the invention are not limited to broadcast programs with a radio data signal, but can also be applied to other radio transmission systems such as e.g. be applied to digital broadcasting.
  • both the broadcast programs and the supplemental information representing the digital information are transmitted digitally.
  • the digital broadcasting programs and the digital information e.g. Traffic messages are displayed, and are issued by various transmitters to receive and output the digital information regardless of the issuing broadcast program, in addition a label for the transmitter of the digital information is output.
