Description

Method and apparatus of providing / receiving Web-based service of multiple of service providers

The present invention relates to a method and apparatus for providing / receiving services of a plurality of service providers, and more particularly, to a method and apparatus for searching for and receiving a web service provided by a plurality of IPTV service providers through an IPTV network.

IPTV (Internet Protocol Television) refers to a service that provides information services, moving picture content, and broadcasting to a TV through an IP network, that is, a high-speed Internet network. With the convergence of telecommunications and broadcasting services in earnest, interest in IPTV is increasing. It is expected that the activation of IPTV will affect not only the telecommunications and broadcasting industries but also the contents and consumer electronics industries.

In order to receive IPTV service through an IP network, a client must have a separate IPTV set-top box. Only a client having an IPTV set-top box manufactured to a standard determined by a service provider providing an IPTV service can receive the IPTV service of the service provider. For example, if there are three IPTV service providers of Company A, Company B, and Company C, a service consumer who purchased Company A's set-top box can only use Company A's IPTV service and use Company B or Company's IPTV service. In order to provide a set-top box of Company B or Company C separately. As such, a different IPTV network for each service provider is called a managed network, and the compatibility problem between the IPTV service provider and the set-top box under the management network narrows the choice of service consumers, and consequently degrades the quality of the IPTV service. It may also be an obstacle to expanding the base of IPTV service.

In order to solve the compatibility problem between the IPTV service provider and the set-top box, the Open IPTV Forum is recently formed and the standardization is being discussed. The forum is under discussion to create a common specification that is not dependent on IPTV service providers and to provide IPTV services to service consumers based on this.

Can be. When the client 210 first attempts to connect to the search server 230, the search server 230 first requests the client 210 to be authenticated from the authentication management entity. The client 210 receiving the request may request authentication from the authentication management entity, and the authentication management entity may perform authentication by transmitting an authentication result to the client 210 and the search server 230. Authentication may be performed by transmitting a predetermined encryption key to the client 210 to access the search server 230.

In operation 256, the client 110 requests a first service, that is, a service providing a feed, based on the information about the IPTV service received in operation 254. The client selects the first service based on the information on the IPTV services received in step 254, and the client 210 requests the first server to provide the first service selected in step 256. Here, the first service is a service for providing a feed.

In operation 258, the client 210 receives a feed from the first server 240. Receive the feed requested in step 256.

In operation 260, the client 210 receives a feed from the first server 240 again. The first server 240 periodically transmits a feed to the client 210 so that the client 210 can periodically update the web information. Steps 256 through 260 are performed using an interface defined between the client 210 and the first server 240 for requesting and transmitting the service.

Based on the received feed, the client 210 may request web information. The transmission of the AV content may be requested to the first server 240 based on the received feed.
