Abstract

Embodiments are disclosed of methods and systems for providing information in a single FM tuner system. An example method according to the disclosure provides station information in a single FM tuner system, and comprises receiving radio data system (RDS) data/radio broadcast data system (RBDS) data by the single FM tuner system; extracting frequency information regarding receivable stations from the received RDS/RBDS data and displaying a list of the receivable frequencies; extracting additional information regarding the receivable stations from the received RDS/RBDS data, and displaying the extracted additional information regarding the receivable stations in correspondence with the respective receivable frequencies in the list. Further a single FM tuner system is provided for carrying out the method.

First claim

The invention claimed is:

1. A method of providing station information in a single FM tuner system, the method comprising:
receiving one or more of radio data system (RDS) data and radio broadcast data system (RBDS) data by the single FM tuner system;
extracting frequency information regarding a plurality of receivable stations from the received RDS and/or RBDS data;
extracting first additional information regarding the plurality of receivable stations from at least one of a program type (PTY) information field and a program identification (PI) information field of the received RDS and/or RBDS data, the first additional information being different from a program service (PS) name;
displaying a list of the plurality of receivable stations based on the extracted frequency information and the extracted first additional information;
selecting a station based on the first additional information by a user of the single FM tuner system;
extracting second additional information comprising the PS name of the selected station when the corresponding RDS and/or RBDS data has been received; and
updating the displayed list of the plurality of receivable stations based on the extracted second additional information by replacing the extracted first additional information with the PS name of the selected station.

2. The method of claim 1 , wherein displaying the list of the plurality of receivable stations comprises displaying a list of a plurality of respective receivable frequencies and displaying the extracted first additional information regarding the plurality of receivable stations in correspondence with the plurality of respective receivable frequencies in the list.

3. The method of claim 2 , wherein the extracted first additional information from the PTY information field comprises a PTY code, wherein the method further comprises assigning a first clear text to the PTY code, and wherein displaying the extracted first additional information further comprises displaying the first clear text.

4. The method of claim 3 , wherein the extracted first additional information from the PI information field comprises a PI code, wherein the method further comprises assigning a second clear text PI code, and wherein displaying the extracted first additional information further comprises displaying the second clear text.

5. The method of claim 4 , wherein the first clear text is assigned to the PTY code and/or the second clear text is assigned to the PI code using an assignment table stored in a database of the single FM tuner system.

6. A single FM tuner system, comprising:
a receiver for receiving one or more of radio data system (RDS) data and radio broadcast data system (RBDS) data;
a display for displaying information; and
a processor for extracting frequency information regarding a plurality of receivable stations from the received RDS and/or RBDS data;
wherein the processor is further configured for extracting first additional information regarding the plurality of receivable stations from at least one of a program type (PTY) information field and a program identification (PI) information field of the received RDS and/or RBDS data prior to extracting a program service (PS) name and for sending display data to the display for displaying a list of the plurality of receivable stations based on the extracted frequency information and the extracted first additional information, and
wherein the display is configured to display the list of the plurality of receivable stations, and
further comprising a selection mechanism for selecting a station by a user of the single FM tuner system based on the first additional information,
wherein the processor is further configured for extracting second additional information comprising the PS name of the selected station when the corresponding RDS and/or RBDS data has become available, and
sending updated display data to the display for displaying an updated list of the plurality of receivable stations based on the extracted second additional information by replacing the extracted first additional information with the PS name of the selected station.

7. The single FM tuner system according to claim 6 , wherein displaying the list of the plurality of receivable stations comprises displaying a list of a plurality of respective receivable frequencies and displaying the extracted first additional information in correspondence with the plurality of respective receivable frequencies in the list.

8. The single FM tuner system according to claim 7 , wherein the extracted first additional information from the PTY information field comprises a PTY code, and wherein the processor is further configured to assign a first clear text to the PTY code and the display is further configured to display the first clear text.

9. The single FM tuner system according to claim 8 , wherein the extracted first additional information from the PI information field comprises a PI code, and wherein the processor is further configured to assign a second clear text to the PI code and the display is further configured to display the second clear text.

10. The single FM tuner system according to claim 9 , further comprising a database for storing an assignment table for assigning the first clear text to the PTY code and/or the second clear text to the PI code.

11. A single FM tuner system, comprising:
a receiver for receiving one or more of radio data system (RDS) data and radio broadcast data system (RBDS) data;
a display device for displaying information;
a processor;
memory storing an assignment table for assigning coded information to associated clear text for presentation to a user, the memory further storing instructions executable by the processor to:
extract frequency information regarding a plurality of receivable stations from the received RDS and/or RBDS data,
extract first additional information regarding the plurality of receivable stations from at least one of a program type (PTY) information field and a program identification (PI) information field of the received RDS and/or RBDS data prior to extracting a program service (PS) name, the first additional information including coded information,
send display data to the display device for displaying a list of the plurality of receivable stations based on the extracted frequency information and the extracted first additional information, and
send instructions to control the display device to display the list of the plurality of receivable stations; and

a selection mechanism for selecting a station by a user of the single FM tuner system based on the extracted first additional information,
wherein the instructions are further executable to:
extract second additional information comprising the PS name of the selected station when the corresponding RDS and/or RBDS data is available, and
send updated display data to the display device for displaying an updated list of the plurality of receivable stations based on the extracted second additional information by replacing the extracted first additional information with the PS name of the selected station.

12. The single FM tuner system according to claim 11 , wherein displaying the list of the plurality of receivable stations comprises displaying a list of a plurality of respective receivable frequencies and displaying the extracted first additional information in correspondence with the plurality of respective receivable frequencies in the list.

13. The single FM tuner system according to claim 12 , wherein the extracted first additional information from the PTY information field comprises a PTY code, and wherein the instructions are further exe
