Abstract

A method and apparatus for receiving an application for providing an Internet protocol television (IPTV) communication service. The method includes: acquiring IP address information for initiating an IPTV service provider discovery at an entry point for searching for a service provider; receiving information regarding an IPTV service provider from an IPTV service provider discovery entity apparatus by using the IP address information; and acquiring information regarding the application for providing the IPTV communication service based on the information regarding the IPTV service provider.

Claims

1. A method of receiving information regarding an application for providing an Internet protocol television (IPTV) communication service, the method comprising:

acquiring IP address information for initiating an IPTV service provider discovery at an entry point for searching for an IPTV service provider;

receiving information regarding the IPTV service provider, from an IPTV service provider discovery entity apparatus by using the IP address information; and

acquiring information regarding the application for providing the IPTV communication service, based on the information regarding the IPTV service provider.

2. The method of claim 1, wherein the application for providing the IPTV communication service includes at least one of a chatting application, an instant message application, a caller identification (ID) application, and a presence application.

3. The method of claim 1, wherein if the information regarding the IPTV service provider includes information for acquiring the application for providing the IPTV communication service, the method further comprises acquiring information regarding the application for providing the IPTV communication service, from the IPTV service discovery entity apparatus by using the information for acquiring the application for providing the IPTV communication service.

4. The method of claim 1, wherein the information regarding the application for providing the IPTV communication service includes uniform resource identifier (URI) information regarding the application for providing the IPTV communication service, which is operable to access the IPTV communication service provided by the IPTV service provider.

5. The method of claim 1, wherein the information regarding the application for providing the IPTV communication service includes at least one of an application ID that is operable to access the IPTV communication service provided by the IPTV service provider, name of the application, uniform resource identifier (URI) information for receiving an application icon, a kind of the application, information regarding technology used in the application, priority of the application, URI information for accessing the application through multicast, and URI information for accessing the application through unicast.

6. The method of claim 2, wherein the information regarding the application for providing the IPTV communication service may include uniform resource identifier (URI) information regarding at least one of the chatting application, the instant message application, the caller ID application, and the presence application provided by the IPTV service provider.

7. The method of claim 1, wherein the information regarding the application for providing the IPTV communication service is provided as a part of a communication offering record.

8. The method of claim 1, wherein the information regarding the IPTV service provider and the information regarding the application for providing the IPTV communication service are in extensible markup language (XML) format.

17. A computer readable recording medium having embodied thereon a computer program for executing the method according to claim 1.

18. The method of claim 2, wherein the presence application relates to an online status or a location of a user.

9. An open Internet protocol television (IPTV) terminal function (OITF) apparatus comprising:

a service provider discovery launcher which acquires IP address information for initiating an IPTV service provider discovery at an entry point for searching for an IPTV service provider;

a service provider information receiving unit which receives information regarding the IPTV service provider, from an IPTV service provider discovery entity apparatus by using the IP address information; and

an application information acquiring unit which acquires information regarding an application for providing an IPTV communication service, based on the information regarding the IPTV service provider.

10. The OITF apparatus of claim 9, wherein the application for providing the IPTV communication service includes at least one of a chatting application, an instant message application, a caller identification (ID) application, and a presence application.

11. The OITF apparatus of claim 9, wherein if the information regarding the IPTV service provider includes information for acquiring the application for providing the IPTV communication service, the application information acquiring unit acquires information regarding the application for providing the IPTV communication service, from the IPTV service discovery entity apparatus by using the information for acquiring the application for providing the IPTV communication service.

12. The OITF apparatus of claim 9, wherein the information regarding the application for providing the IPTV communication service includes uniform resource identifier (URI) information regarding the application for providing the IPTV communication service, which is operable to access the IPTV communication service provided by the IPTV service provider.

13.
