Abstract: Provided are a method and apparatus for providing/receiving a service from a plurality of service providers. In the method, in order to receive a service from a plurality of Internet protocol television (IPTV) service providers, a client receives information regarding at least one of a feed that syndicates web information and a web-based application from a server of a service provider selected from the IPTV service providers. Then, the client requests the server to provide a service providing at least one of the feed and the application based on the received information, and receives the service from the server. Accordingly, it is possible to provide or receive web-based services via an IPTV network.

Abstract: Provided is a method of controlling a security level of a device. The method includes: requesting a server to authenticate a device, wherein the requesting is performed by a second application installed in the device; generating a device-server session for communication between the server and the device, based on the authentication of the device by the server; requesting access to the server by using the generated device-server session, wherein the requesting is performed by a first application installed in the device; and receiving content from the server due to the first application accessing the server.

Abstract: A multimedia content conversion apparatus and method, and a multimedia content distribution system are provided. The apparatus includes a storage unit storing original data received from a multimedia content provider, an authentication unit determining whether a viewer is authorized with respect to the original data stored in the storage unit, a decryptor decrypting the original data if it is determined by the authentication unit that the viewer is authorized, and a data combiner combining the original data and the data decrypted by the decryptor. Accordingly, even if several TVs are installed in a home, a viewer can view desired multimedia content through all of the TVs with only one content conversion apparatus. Even when the viewer watches a TV in which the content conversion apparatus is not included, the viewer can view desired multimedia content by changing a channel of a TV which includes the content conversion apparatus.

Abstract: A method for transmitting information effectively in a server/client network system is provided, the network system including a client placed behind a firewall and a server that provides the client with a predetermined service.
