12. The method of claim 2, wherein, when the application providing the IPTV service is the content guide application, the second apparatus performs a function corresponding to an entity defined in an open IPTV forum architecture, wherein the second apparatus is an IPTV service discovery entity apparatus for searching for at least one service provided by an IPTV service provider.

35. A computer readable recording medium having recorded thereon a program for executing the method of claim 1.

13. A method of transmitting metadata regarding an application providing an Internet Protocol Television (IPTV) service of a second apparatus, the method comprising:

receiving metadata request message for requesting metadata regarding the application providing an IPTV service;

generating a metadata response message comprising the metadata regarding the application providing the IPTV service, in response to the metadata request message; and

transmitting the metadata response message to a first apparatus.

14. The method of claim 13, wherein the application providing the IPTV service comprises at least one application from among an IPTV service discovery application, and a content guide application.

15. The method of claim 14, wherein, when the application providing the IPTV service is the IPTV service discovery application, the metadata comprises uniform resource identifier (URI) information regarding the IPTV service discovery application for searching for at least one service provided by an IPTV service provider.

16. The method of claim 14, wherein, when the application providing the IPTV service is the content guide application, the metadata comprises uniform resource identifier (URI) information regarding the content guide application for extracting content guide information.

17. The method of claim 14, wherein, when the application providing the IPTV service is the IPTV service discovery application, the metadata is provided as a part of a service provider record.
