Abstract

Methods and systems for transmitting electronic service guide (ESG) data to a mobile terminal are described. The method for delivery of ESG data comprises steps of receiving ESG data, encapsulating metadata associated with the ESG data to generate a new ESG object, replacing a current ESG object with the new ESG object, transmitting the new ESG object in a carousel, and transmitting a notification of a change in the carousel. Another method for receiving ESG data comprises steps of receiving a notification of a change in a carousel, receiving a new ESG object in the carousel, replacing a current ESG object with the new ESG object, extracting metadata associated with ESG data from the new ESG object, storing the ESG data and metadata, and updating an ESG on a mobile terminal with the ESG data.

Claims

1. A method for delivering electronic service guide (ESG) data, the method comprising steps of:

receiving ESG data;

encapsulating metadata associated with the ESG data to generate a new ESG object;

replacing a current ESG object with the new ESG object;

transmitting the new ESG object in a carousel; and

transmitting a notification of a change in the carousel.

2. The method of claim 1, further comprising a step of detecting an occurrence of a triggering event.

4. The method of claim 1, wherein the ESG data is created in response to an operator input.

5. The method of claim 1, wherein the ESG data is one of:

a new ESG data and a modified ESG data.

6. The method of claim 1, wherein the new ESG object includes a channel object component, at least one channel session description protocol (SDP) component, and at least one program object component.

7. The method of claim 6, wherein the channel object component includes channel metadata and channel classification and rating data.

8. The method of claim 6, wherein the at least one channel SDP component includes a description of use and mobile terminal capabilities, audio/video media and address information and synchronized auxiliary data address information.

9. The method of claim 6, wherein the at least one program object component includes program metadata, program interaction references, and program classification and rating data.

10. The method of claim 6, wherein the new ESG object further includes a channel package object component, at least one price object component, and at least one purchase channel object component.

11. The method of claim 10, wherein the at least one price object component includes price information data and additional metadata.

12. The method of claim 10, wherein the at least one purchase channel object includes operator identity data and purchase transaction technical data.

13. The method of claim 1, wherein the notification of the change in the carousel is a notification of the new ESG object.

14. A computer-readable medium storing computer-executable instructions for performing the steps recited in claim 1.

3. The method of clam 2, wherein the step of receiving ESG data is responsive to the step of detecting an occurrence of a triggering event.

15. A method for receiving electronic service guide (ESG) data at a mobile terminal, the method comprising steps of:

receiving a notification of a change in a carousel;

receiving a new ESG object in the carousel;

replacing a current ESG object with the new ESG object;

extracting metadata associated with ESG data from the new ESG object;

storing the ESG data and metadata.

16. The method of claim 15, further comprising a step of determining when to update the ESG data on the mobile terminal.

17. The method of claim 16, wherein the step of determining is based on power consumption.

18. The method of claim 15, wherein the ESG data is one of:

a new ESG data and a modified ESG data.

19. The method of claim 15, wherein the new ESG object includes a channel object component, at least one channel session description protocol (SDP) component, and at least one program object component.
