Abstract

An image display device is provided. A broadcast receiving unit receives a broadcast signal. A control unit installs and uninstalls, according to a user input, a broadcast service receiving application that receives a broadcast service in the broadcast signal.

Claims

1. An image display device comprising:

a broadcast signal receiving unit receiving a broadcast signal; and

a control unit installing and uninstalling, according to a user input, a broadcast service receiving application that receives a broadcast service in the broadcast signal.

2. The image display device according to claim 1, further comprising an internet protocol (IP) communication unit that transmits information on the image display device and information on a user of the image display device, to a subscription information server that manages information on a broadcast service package subscriber,

wherein the subscription information server changes broadcast service information on the broadcast service based on the information on the image display device and the information on the user of the image display device.

3. The image display device according to claim 2, wherein the information on the image display device comprises an image display device identifier that identifies the image display device.

4. The image display device according to claim 2, wherein the information on usage of the image display device comprises a user identifier that identifies the user of the image display device, and a password that corresponds to the user identifier.

5. The image display device according to claim 2, wherein the IP communication unit transmits a service package identifier that identifies a service package to which the user of the image display device subscribes, and

the subscription information server changes broadcast service information on the broadcast service based on the service package identifier.

6. The image display device according to claim 2, wherein the broadcast service information comprises conditional access system (CAS) data that is needed to descramble a scrambled broadcast stream.

7. The image display device according to claim 1, further comprising an internet protocol (IP) communication unit that transmits information on a version of the broadcast receiving application to a subscription information server managing information on a broadcast service package subscriber, and receives whether there is a need to upgrade the broadcast service receiving application.

8. The image display device according to claim 7, wherein the control unit upgrades the broadcast service receiving application to a higher version of broadcast service receiving application through a background process that is performed without usage of the image display device by a user.

9. The image display device according to claim 7, wherein the control unit upgrades the broadcast service receiving application to a higher version of broadcast receiving application at a time that is determined based on a user input.

10. The image display device according to claim 7, wherein the control unit upgrades the broadcast service receiving application to a higher version of broadcast receiving application, when a user'"'"'s turn-off input related to the image display device is received.

11. A method of operating an image display device, the method comprising:

receiving a broadcast signal through a broadcast signal receiving unit; and

receiving a broadcast service in the broadcast signal through a broadcast service receiving application that is controlled by a control unit,

wherein the broadcast service receiving application is installed and un-installed according to a user user input.

12. The method according to claim 11, further transmitting information on the image display device and information on a user of the image display device, to a subscription information server that manages information on a broadcast service package subscriber, through an internet protocol (IP) communication unit,

wherein the subscription information server changes broadcast service information on the broadcast service based on the information on the image display device and the information on the user of the image display device.

13. The method according to claim 12, wherein the information on the image display device comprises an image display device identifier that identifies the image display device.

14. The method according to claim 12, wherein the information on usage of the image display device comprises a user identifier that identifies the user of the image display device, and a password that corresponds to the user identifier.

15. The method according to claim 12, wherein the transmitting of the information on the image display device and information on a user of the image display device, to the subscription information server comprises transmitting a service package identifier that identifies a service package to which the user of the image display device subscribes, and

the subscription information server changes broadcast service information on the broadcast service based on the service package identifier.

16. The method according to claim 12, wherein the broadcast service information comprises conditional access system (CAS) data that is needed to descramble a scrambled broadcast stream.

17. The method according to claim 11, further comprising:

transmitting version information on the broadcast receiving application, to a subscription information server that manages information on a broadcast service package subscriber, through an internet protocol (IP) communication unit; and

receiving whether there is a need to upgrade the broadcasting service receiving application, through the IP communication unit.

18. The method according to claim 17, further comprising upgrading, through a control unit, the broadcast service receiving application to a higher version of broadcast service receiving application through a background process that is performed without usage of the image display device by a user.

19. The method according to claim 17, further comprising upgrading, through a control unit, the broadcast service receiving application to a higher version of broadcast receiving application at a time that is determined based on a user input.

20. The method according to claim 17, further comprising upgrading, through the control unit, the broadcast service receiving application to a higher version of broadcast receiving application, when a user'"'"'s turn-off input related to the image display device is received.
