Abstract

Disclosed herein is a method and system for providing service search. The system for providing service search includes an index formation unit, a container configuration unit, a guide configuration unit, and a transmission and reception unit. The index formation unit forms an index structure including an index list area, an index area, and a sub-index area. The container configuration unit configures an integrated container by integrating service information, schedules, and program information for each of service identifiers (IDs) included in the sub-index area. The guide configuration unit configures an Electronic Program Guide (EPG) including the index structure. The transmission and reception unit provides the EPG using a service ID corresponding to information desired by the terminal, together with the index structure.

Claims

1. A system for providing service search, comprising:

an index formation unit for forming an index structure including an index list area, an index area, and a sub-index area;

a container configuration unit for configuring an integrated container by integrating service information, schedules, and program information for each of service identifiers (IDs) included in the sub-index area;

a guide configuration unit for configuring an Electronic Program Guide (EPG) including the index structure; and

a transmission and reception unit for providing the EPG using a service ID corresponding to information desired by a terminal, together with the index structure.

2. The system as set forth in claim 1, wherein the index list area includes a fragment type, a field and an index pointer, the index area includes a service search range, and the sub-index area includes the service IDs and corresponding container locators corresponding to a location information list of information included in the service search range of the field.

3. The system as set forth in claim 2, wherein the fragment type includes program information, a program location, and service information.

4. The system as set forth in claim 3, wherein the program information, the program location, and the service information are sequentially described in XML Path Language (Xpath).

5. The system as set forth in claim 1, wherein the field includes a service ID and a start time of a schedule corresponding to the service information.

6. The system as set forth in claim 1, wherein the EPG comprises schedules and program information for a specific period of time.

7. The system as set forth in claim 1, wherein the container configuration unit integrates the service information, the schedules and the program information into an XML document type.

8. A method for providing service search, comprising:

forming an index structure including an index list area, an index area, and a sub-index area;

configuring an integrated container by integrating service information, schedules, and program information for each of service IDs included in the sub-index area;

configuring an Electronic Program Guide (EPG) including the index structure; and

providing the EPG using a service ID corresponding to information desired by a terminal.

9. The method as set forth in claim 8, wherein the forming the index structure list area comprises forming the index list region, including a fragment type, a field, and an index pointer.

10. The method as set forth in claim 9, wherein the fragment type includes program information, a program location, and service information.

11. The method as set forth in claim 10, wherein the forming an index structure comprises forming the index area, including a service search range of the field in the index list area.

12. The method as set forth in claim 11, wherein the forming the index structure comprises forming the sub-index area, including the service IDs and container locators corresponding to a location information list of information included in the service search range of the field.

13. The method as set forth in claim 9, wherein the forming the index list area comprises sequentially describing the fragment type in XML Path Language (Xpath).

14. The method as set forth in claim 8, wherein the EPG comprises schedules and program information for a specific period of time.
