Abstract

PROBLEM TO BE SOLVED: To effectively broadcast programs by receiving and outputting the digital information of another broadcasting station without relying upon an outputted broadcasting program. SOLUTION: Since the output of an audio broadcasting program is performed without relying upon the reception of radio data signals RDS by means of a second tuner 2, the tuner 2 can scan RDS data in another receiving frequency. Therefore, a microprocessor 3 can file the RDS data of another program service provider in a second memory 5. Then the RDS data instantaneously received by means of the microprocessor 3 are outputted through an indicating device 9 optically or a sound synthesizer 7 and a loudspeaker 8 in accordance with the operation mode inputted from an input unit 10. In this case, the output of useful RDS data is caused by operating the keys of the input unit 10.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for receiving and outputting a broadcast program accompanied by added digital information, which is described in the preamble of claim 1.

[0002]

2. Description of the Related Art It is already known from the radio broadcasting system based on the radio data system (RDS) to add digital information in the form of RDS data to a broadcasting program. The broadcast program and the digital information are received and output by the radio receiver according to claim 12. This can be seen, for example, in Franz Stollenberg, “RDS-ein neuer
Dienst im UKW-Rundfunk ”, NTZ, Band 40,1987, Heft 5,
It is described on page 346.

A radio data system is a system in which additional, inaudible digital data is transmitted with a broadcast program.

A radio receiver equipped with a suitable RDS decoder receives the transmitted RDS data in the same receiving section in addition to the radio reception, decodes the RDS data and outputs it again. Information, eg traffic information, is transmitted by codewords over the RDS data channel. At this time, the place of occurrence of the event and the event itself are transmitted. Instead of traffic information, any other RDS useful data can be transmitted, for example event instructions. In addition to the RDS useful data, the received RDS data has in particular a program identifier and a program service number. The program identifier represents the RDS data broadcasting station, and the program service number represents the name of the RDS data broadcasting station.

It is also known to digitally broadcast broadcast programs and digital information, such as traffic information, using digital broadcasting (DAB) and output the broadcast programs and digital information.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to make it possible to output digital information of an arbitrary broadcasting station without depending on a tuned radio broadcasting station listening to a broadcasting program. is there.

[0007]

According to the present invention, the above problem can be solved by receiving digital information of another broadcasting station and outputting the digital information without depending on the broadcast program to be output.

[0008]

According to the present invention, even when a broadcasting station is selected for a broadcasting program, it is possible to output digital information of another broadcasting station without depending on the selected broadcasting station. it can. Therefore, the listener is not limited to the information of the broadcast program. This is especially advantageous in the case of the multi-tuner concept. In the multi-tuner concept, the first tuner receives the broadcast program and the second tuner receives the digital information.

Here, for example, digital broadcasting (DA
B), or a broadcast program with a radio data signal (RDS) can be used.

Advantageous refinements of the method according to claim 1 and the radio receiver according to claim 12 are possible by means of the measures specified in the dependent claims. In a preferred embodiment of the method according to the invention, the RDS digital information of the radio data signal is used as the digital information, and in addition to the RDS useful data, the identifier of the broadcasting station of the RDS data is output. This ensures that the listener has information about from which broadcast station the RDS useful data being output is transmitted. As a result, the output RDS useful data can be uniquely assigned to the broadcasting station.

In another advantageous configuration of the method according to the invention, RD
The program identifier of the broadcasting station of the RDS data is stored together with the S data. In this way, the received RDS data can be assigned to the broadcasting station of the RDS data easily and reliably.

Another advantageous embodiment of the method according to the invention uses a table, which has a direct correspondence between the program identifier and the identifier of the broadcasting station of the RDS data, eg the program service name. This allows the identifier of the broadcasting station to be read easily via the program identifier. Thereby, it is not necessary to always obtain the identifier of the broadcasting station from the RDS data itself after receiving the RDS data.

Particularly advantageously, the program service name is output in parallel with the RDS data, eg traffic information, in time.

The program service name of the broadcast program and the program service name of the RDS data can be easily distinguished as follows. That is, the program service name of the broadcasting station of the RDS data is output as sound,
Alternatively, it is displayed on the display in a prominent form, for example in capital letters and / or blinking and / or in reverse video and / or in a prominent color.

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 schematically shows a radio receiver having two tuners. The antenna 6 is connected to the input side of the first tuner 1 via the first antenna line 11. The first tuner is the first receiver. First
The tuner 1 of is connected to the input side of the second tuner 2 via the second antenna line 12. The second tuner is the second receiver. The second tuner 2 is connected to the microprocessor 3 via the second output line 13. Similarly, the first tuner 1 is connected to the first output line 14
Is connected to the microprocessor 3 via.

The microprocessor 3 is connected to the input unit 10 via the first line 15. Further, the microprocessor 3 uses the optical data indicating device 9 via the second data line 16, the first memory 4 via the third data line 17, and the second memory 5 via the fourth data line 18. , And the fifth data line 15 to be connected to the audio synthesizer 7. The voice synthesizer 7 is the sixth
Is connected to the speaker 8 via the data line 20. The microprocessor 3 is connected to the speaker 8 via the audio line 21.

The device of FIG. 1 operates as follows. The reception signal is received by the first tuner 1 via the antenna 6. The first tuner 1 is tuned to one broadcasting station and further conducts the broadcasting program of this broadcasting station to the microprocessor 3. The microprocessor 3 outputs the received broadcast program as an audio signal via the audio line 21 and the speaker 8. At the same time, the received signal is provided to the second tuner 2 via the first tuner 1. The second tune 2 is tuned to the second station and receives the RDS data, which is further conducted to the microprocessor 3. The microprocessor 3 detects the RDS useful data from the supplied RDS data, such as traffic information, program identifiers and program service names. The microprocessor 3 stores the RDS useful data and the program identifier of the RDS data in the second memory 5
To memorize.

In addition, 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. This is the case when the program identifier and the program service name are not yet filed in the first memory 4. The table provides a direct correspondence between program identifiers and program service names.

Instead of the RDS data, preferably the second tuner also receives the digital side information of the digital broadcasting program and detects from this side information useful data, eg traffic information and an identifier for the station of the side information according to the method described above. To do. The useful data and the identifier are output according to the above method without depending on the output broadcast program.

It is advantageous to store the program identifier and the program service name respectively when changing the broadcast station of the RDS data. This is because, when changing a broadcasting station, it is possible that the new broadcasting station uses the changed correspondence between the program identifier and the broadcasting station identifier.

Broadcast program output (audio signal)
Is performed without depending on the reception of the RDS data by the second tuner 2, the second tuner 2 can scan the RDS data at another reception frequency, which allows the microprocessor 3 to execute another program. The RDS data of the service provider can be filed in the second memory 5.

Depending on the operating mode input by the input unit 10, the instantaneous RDS data received by the microprocessor 3 is optically transmitted via the indicating device 9,
Alternatively, the sound is output acoustically via the voice synthesizer 7 and the speaker 8.

The microprocessor 3 advantageously outputs the program service name acoustically or optically in parallel with the RDS data. In order to make the program service name of the RDS data provider stand out from the program service name of the audio data provider, the display of the program service name of the RDS data provider is preferably capitalized and / or blinking. And / or in reverse video and / or in a prominent color different from other displays of the optical pointing device 9.

A table is stored in the first memory 4, and a direct correspondence between the program identifier and the program service name is possible by this table. As a result, the microprocessor 3 can detect the program service name of the provider of the RDS data via the program identifier in the received RDS data. This has the advantage that the program service name only needs to be detected once from the RDS data. Detecting program service names is relatively cumbersome.

The RDS data is output by the input unit 10
After the input is done via, the method is performed according to the method of the present invention.

For this purpose, the keys of the input unit 10 are operated to cause the output of RDS useful data. The method according to the invention is therefore particularly suitable for the output of traffic information (“traffic message channels”) which is collected and output on demand.

FIG. 2 shows the program sequence for implementing the method of the invention.

At program point 30, the first tuner 1 receives a broadcast program (audio signal) at a predetermined reception frequency. This broadcast program is output via the microprocessor 3 and the speaker 8. Second at the same time
The tuner 2 receives the RDS data of the broadcasting station. The broadcaster or the program provider of the RDS data may be (but need not be) the same as the broadcast station received by the first tuner 1.

At program point 31, the RDS data is further conducted to the microprocessor 3. The microprocessor 3 files the RDS useful data and the program identifier of the RDS data in the second memory 5. The microprocessor 3 now checks at program point 32 whether the received RDS useful data matches the RDS useful data already stored in the second memory 5. If the received RDS useful data is new, the microprocessor 3 will
Then, the table stored in the first memory 4 is scanned for the program identifier of the newly received RDS data.

If the program identifier of the newly received RDS data is not yet filed in the first memory 4, the program identifier and the program service name are first filed by the microprocessor 3 in the first memory 4, ie in the table. To be done. For this purpose, the microprocessor 3 has to detect the program service name from the RDS data. The program service name is then read from the table and output at program point 33 along with the RDS useful data. Next, program point 30
Branch back to.

When it is determined that there is not, the process branches back to the program point 30.

If the inquiry at program point 32 reveals that the RDS useful data is not new, ie if both the RDS useful data and the program identifier and the program service name have already been stored, then a manual operation at program point 34 will result in an input unit 10. If a manual operation is performed, the RD stored at the program point 35 is inquired.
S useful data is output with each program service name. Then, a return branch is made to the program point 30. Inquiry at program point 34,
When it is determined that no input has been made, a return branch is made to the program point 30.

If the output of the traffic information is carried out via the loudspeaker, the output of the program service name is advantageously also carried out via the loudspeaker 8 either before the output of the traffic information or after the output of the traffic information.

Alternatively, however, the program service name can be optically output in parallel with the acoustic output of traffic information via the optical indicating unit. If the traffic information is output via the optical pointing device, the program service name is output via the optical pointing unit 9 before or after the output of the traffic information as well. The optical indicating unit 9 or the speaker 8 is used as an output device.

The program service name is prominently displayed on the optical output. This allows the service name to be distinguished from other displays on the optical pointing unit 9. This is done, for example, in capital letters or in a blinking display and / or in reverse video and / or in a prominent color different from the color of the other displays of the optical indicating unit 9.

If the same traffic information is received from different broadcasting stations, another advantageous configuration of the method according to the invention is:
The program identifier of the broadcast station that first received the traffic information is stored.

In an additional advantageous configuration of the invention, the program identifier of the station which received the traffic information last is stored.

The method of the invention and the radio receiver of the invention have been described as examples for broadcast programs with radio data signals. However, the method and radio receiver of the invention are not limited to broadcast programs with radio data signals, but can also be applied to other broadcast transmission systems, for example digital broadcasts.

In the case of digital broadcasting, both the broadcasting program and additional information representing digital information are transmitted digitally. By the method of the present invention and the apparatus of the present invention, it is possible to receive a broadcast program and digital information representing traffic information, for example, even if they are transmitted from different broadcasting stations, and output the digital information without depending on the broadcast program to be output. You can In this case, the identifier of the digital information broadcasting station is additionally output.
