Abstract

A method and apparatus for receiving information regarding the displaying of a service in a digital audio broadcasting (DAB) receiver via a fast information channel and for controlling the displaying of the service on the DAB receiver are provided. The method includes receiving a digital audio broadcasting transmission frame and parsing information regarding a sub channel and a service component related to a service selected by a user, and obtaining information required to display the selected service by parsing information from a channel that is differentiated from a data service channel. Accordingly, it is possible to display various types of services regardless of the DAB receiver used, thereby allowing effective use of a user interface.

Claims

1. A method of transmitting information regarding displaying of a service in digital audio broadcasting, comprising:

providing display information required to display the service in a channel that is differentiated from a service data channel; and

combining the display information into a digital audio broadcasting transmission frame and transmitting the digital audio broadcasting transmission frame.

2. The method of claim 1, wherein the channel in which the display information is included is a fast information channel.

3. The method of claim 2, wherein:

the fast information channel comprises predetermined sized fast information blocks,

each of the fast information blocks includes a data field including at least one fast information group, and

the display information is contained in one of the fast information groups in each of the fast information blocks.

4. The method of claim 3, wherein the fast information group comprises:

a service identification field in which identification of a service is recorded;

a service component identification field in which identification of a plurality of service components constituting the service is recorded;

a coordinate field in which coordinates of the position on a screen where displaying of the service components starts are recorded; and

a size field in which information regarding the widths and heights of the displayed service components are recorded.

20. The method of claim 1, wherein the display information required to display the service includes the display information required to display the service with a receiver.

21. The method of claim 1, wherein combining the display information into the digital broadcasting transmission frame includes multiplexing the display information into the digital audio broadcasting transmission frame.

5. A method of receiving and displaying information regarding displaying of a service in digital audio broadcasting, comprising:

receiving a digital audio broadcasting transmission frame including channels and service information;

parsing service information regarding a sub channel and a service component related to a service selected by a user; and

obtaining display position information required to display the selected service by parsing information from a channel that is differentiated from a data service channel.

6. The method of claim 5, further comprising computing the position on a screen where the service component will be displayed using the obtained display position information and the size of a screen of a receiver.

7. The method of claim 6, wherein the channel in which the display information is included is a fast information channel.

8. The method of claim 7, wherein:

the fast information channel comprises predetermined sized fast information blocks, each of the fast information blocks includes a data field including at least one fast information group, and

the display information is contained in one of the fast information groups in each of the fast information blocks.

9. The method of claim 8, wherein the fast information group comprises:

a service identification field in which identification of a service is recorded;

a service component identification field in which identification of a plurality of service components constituting the service is recorded;

a coordinate field in which coordinates of the position on a screen where displaying of the service components starts are recorded; and

a size field in which information regarding the widths and heights of the displayed service components are recorded.

10. The method of claim 9, wherein values of the coordinate field and the size field are computed again using the size of the screen of the receiver.

11. An apparatus for controlling displaying of a service in digital audio broadcasting, comprising:

a service information parser which receives a digital audio broadcasting transmission frame including channels and parses information regarding a sub channel and a service component related to a service selected by a user;

a display information parser which parses information in a channel that is different from a service data channel to obtain information required to display the selected service; and

a display position computing unit which computes the position on a screen where a service component is to be displayed using the resolution of a receiver.

12. The apparatus of claim 11, wherein a channel in which the display information is included is a fast information channel.

13. At least one computer readable medium for storing instructions that control at least one processor which executes a method of receiving and displaying information required to display a service in digital audio broadcasting, wherein the method comprises:

receiving a digital audio broadcasting transmission frame including channels and service information;

parsing service information regarding a sub channel and a service component related to a service selected by a user; and

obtaining display information required to display the selected service by parsing information from a channel that is different from a data service channel.

14. The medium of claim 13, wherein the channel in which the display information is included is a fast information channel.

15. The medium of claim 14, wherein:

the fast information channel comprises predetermined sized fast information blocks;

each of the fast information blocks includes a data field including at least one fast information group; and

the display information is contained in one of the fast information groups in each of the fast information blocks.

16. The medium of claim 13, further comprising computing the position on a screen where the service component will be displayed using the obtained display position information and the size of a screen of a receiver.

17. At least one computer readable medium for storing instructions that control at least one processor which executes a method of transmitting information regarding displaying of a service in digital audio broadcasting, wherein the method comprises:

providing display information required to display the service in a channel that is differentiated from a service data channel; and

combining the display information into a digital audio broadcasting transmission frame and transmitting the digital audio broadcasting transmission frame.

18. The medium of claim 17, wherein the channel in which the display information is included is a fast information channel.

19. The medium of claim 18, wherein:

the fast information channel comprises predetermined sized fast information blocks;

each of the fast information blocks includes a data field including at least one fast information group; and

the display information is contained in one of the fast information groups in each of the fast information blocks.
