Abstract

A method and apparatus for interactively using additional data in digital audio broadcasting. The method of interactively using additional data includes: receiving additional data and storing the received additional data in a specified database; receiving a user input via a user input interface obtained by decoding information regarding a screen composition contained in service data, transforming the user input into a query that requests a search of the database, and outputting the query; and searching the database in response to the query and outputting a result of the searching.

Claims

1. A method of interactively using additional data, comprising:

receiving the additional data and storing the received additional data in a specified database;

receiving a user input via a user input interface obtained by decoding information regarding a screen composition contained in service data, transforming the user input into a query that requests a search of the database, and outputting the query; and

searching the database in response to the query and outputting a result of the searching.

2. The method of claim 1, wherein the database is a relational database.

3. The method of claim 2, wherein the relational database includes:

a field including at least one pair of a field label that categorizes stored data and a field type that represents a format in which the field label is stored; and

field data including at least one pair of an index, and at least one piece of data corresponding to the index and a length of the data.

4. The method of claim 1, wherein the additional data is received in a packet mode in digital audio broadcasting.

5. The method of claim 1, wherein the information regarding the screen composition is received in a stream mode in digital audio broadcasting, and binary format for scene (BIFS) data.

6. The method of claim 1, wherein the user input interface is a BIFS node.

7. The method of claim 1, wherein the receiving a user input includes:

decoding the information regarding the screen composition contained in the service data, to make the user input interface; and

receiving a user input via the user input interface, transforming the user input into the query using a BIFS server command constituting the information regarding the screen composition, and outputting the query.

8. The method of claim 7, wherein the BIFS server command includes:

a uniform resource locator (URL) indicating a position of the database that is to be searched in response to the query; and

a command received via the user input interface.

9. An apparatus for processing additional data, comprising:

a local database receiving the additional data and storing the received additional data; and

a decoder decoding information regarding a screen composition to make a user input interface, receiving a user input via the user input interface, transforming the user input into a query that requests a search of the local database, and outputting the query.

10. The apparatus of claim 9, wherein the local database receives the query, searches data in the local database, and outputs a result of the searching.

11. The apparatus of claim 9, wherein the database is a relational database.

12. The apparatus of claim 11, wherein the relational database includes:

a field including at least one pair of a field label that categorizes stored data and a field type that represents a format in which the field label is stored; and

field data including at least one pair of an index and at least one piece of data corresponding to the index and a length of the data.

13. The apparatus of claim 9, wherein the information regarding the screen composition is received in a stream mode in digital audio broadcasting, and binary format for scene (BIFS) data.

14. The apparatus of claim 9, wherein the user input interface is a BIFS node.

15. A computer-readable storage medium encoded with processing instructions for causing a processor to perform a method of interactively using additional data, the method comprising:

receiving additional data and storing the received additional data in a specified database;

receiving a user input via a user input interface obtained by decoding information regarding a screen composition contained in service data, transforming the user input into a query that requests a search of the database, and outputting the query; and

searching the database in response to the query and outputting a result of the searching.

16. A digital audio broadcast (DAB) system, comprising:

a broadcast station transmitting binary format for scene (BIFS) data in a stream mode and additional data in a packet mode;

a receiver having a BIFS decoder and a database, the receiver receiving the transmitted BIFS data and the transmitted additional data, storing the received additional data in the DB, the BIFS decoder decoding the received BIFS data to obtain a BIFS node receiving user input; and

a user interface,

wherein, when a user input is received by the user interface, a query regarding the user input is made using the BIFS node and the database is searched to satisfy the query.

17. The system of claim 16, wherein the BIFS data is an extension of a virtual reality modeling language (VRML) that realizes virtual reality in an Internet virtual space.

18. The system of claim 17, wherein the BIFS data allows objects encoded with natural or synthetic voice or images, to be arranged in a virtual time-space and allows a user to manipulate the objects.
