Abstract

An apparatus and a method for driving an application, contained in a hybrid multimedia service, in a broadcast system that provides a user equipment with the hybrid multimedia service based on a hybrid network including at least a broadcast network and a network supporting an Internet protocol is provided. To this end, a broadcast server constituting the broadcast system constructs control information to be used for acquiring an instruction table for driving the application contained in the hybrid multimedia service, and transmits the constructed control information to the user equipment in a predetermined format. The user equipment may acquire the instruction table using the control information provided from the broadcast server, and drive a desired application using the acquired instruction table.

First claim

The invention claimed is:

1. A method for supporting a hybrid multimedia service for a user equipment based on a hybrid network that includes at least one of a broadcast network and an internet protocol (IP) network, the method comprising:
constructing, by a broadcast server, control information for providing an application; and
transmitting, by the broadcast server, the constructed control information to the user equipment in a predefined format,
wherein the constructed control information comprises identification information indicating the application, primary information, and secondary information,
wherein each of the primary information and the secondary information comprise location information for acquiring a table, and
wherein the table comprises information corresponding to the identification information, the information comprising command information for providing the application.

2. The method of claim 1 , wherein the primary information comprises the location information and time information for acquiring the table via the broadcast network, and the secondary information comprises the location information for acquiring the table via the IP network.

3. The method of claim 2 , wherein the location information comprised in the primary information and the location information comprised in the secondary information are uniform resource locators (URLs).

4. The method of claim 1 , wherein the constructed control information further comprises content identification information indicating a content to be associated with the application and table identification information identifying the table.

5. The method of claim 1 , further comprising:
providing the table via the hybrid network to the user equipment; and
supporting driving of the application according to a command from the user equipment based on the table.

6. The method of claim 1 , wherein the table further comprises at least one of identification information for identifying the table, version information of the table, validity information corresponding to a validity period of the table, content identification information indicating a content to be associated with the application, and information for updating the table.

7. The method of claim 6 , wherein the command information comprises a command type, a resource to be used, and an execution time for each command.

8. The method of claim 1 , wherein the predefined format is defined by a program association table, a program mapping table, or a network information table.

9. An apparatus for supporting a hybrid multimedia service for a user equipment based on a hybrid network that includes at least one of a broadcast network and an internet protocol (IP) network in a broadcast server, the apparatus comprising:
a control unit configured to construct control information providing an application; and
a transmitter configured to transmit the constructed control information to the user equipment in a predefined format,
wherein the constructed control information comprises identification information indicating the application, primary information, and secondary information,
wherein each of the primary information and the secondary information comprise location information for acquiring a table, and
wherein the table comprises information corresponding to the identification information, the information comprising command information for providing the application.

10. The apparatus of claim 9 , wherein the primary information comprises the location information and time information for acquiring the table via the broadcast network, and the secondary information comprises the location information for acquiring the table via the IP network.

11. The apparatus of claim 10 , wherein the location information comprised in the primary information and the location information comprised in the secondary information are uniform resource locators (URLs).

12. The apparatus of claim 9 , wherein the constructed control information further comprises content identification information indicating a content to be associated with the application and table identification information identifying the table.

13. The apparatus of claim 9 , wherein the transmitter transmits the table via the hybrid network to the user equipment, and supports driving of the application according to a command from the user equipment based on the table.

14. The apparatus of claim 9 , wherein the table further comprises at least one of identification information for identifying the table, version information of the table, validity information corresponding to a validity period of the table, content identification information indicating a content to be associated with the application, and information for updating the table.

15. The apparatus of claim 14 , wherein the command information comprises a command type, a resource to be used, and an execution time for each command.

16. The apparatus of claim 9 , wherein the predefined format is defined by a program association table, a program mapping table, or a network information table.
