A detailed operation of the customized broadcast service providing system according to the present invention having such a configuration will be described in detail with reference to FIGS. 3 and 4.

3 is a flowchart illustrating a processing of a customized broadcast service using a personal electronic program guide according to the present invention.

A user accesses an open service application server through a user interface of a user terminal, logs in to a customized broadcast service, requests a service, and generates related information as metadata through a metadata generator (301). Thereafter, the metadata generated through the metadata transceiver is transferred to the metadata transceiver of the open service application server (302).

The open service application server receives the metadata through the metadata transceiver and parses the metadata received by the metadata transceiver through the metadata parser (303). The open service application server then forwards the parsed request through the service request unit to the service request receiver of the open service gateway (304).

The open service gateway receives the service request through the service request receiver and processes the service received by the service request receiver through the service processor (305). The open service gateway then delivers the processed service to the headend through the service acquisition unit (306).

When the headend receives the service request from the open service gateway, the headend requests information from the electronic program guide in the case of a broadcast service according to the service request (step 307). When the headend receives the requested information from the electronic program guide (308), the headend returns the electronic program guide information to the service acquisition unit of the open service gateway (309).

When the service acquisition unit of the open service gateway receives the electronic program guide information from the headend (309), and transmits the received electronic program guide information to the service delivery unit of the open service application server (310).

When the open service application server receives the electronic program information through the service delivery unit, the open service application server generates the application service based on the information received by the service delivery unit through the application service generation unit. At this time, the application service generation unit generates a customized application service requested by the user. Then, the open service application server generates an application service generated through the metadata generator as metadata (311), and transmits the metadata generated through the metadata transceiver to the metadata transceiver of the user terminal (312).

When the user terminal receives the metadata through the metadata transceiver, the user terminal parses the received metadata through the metadata parser (313). Thereafter, the user terminal shows the parsed service to the user through the user interface, and the user may select information to be output, request a search again, or select content playback.

4 is a flowchart illustrating a customized broadcast service using a remote digital recorder according to the present invention.

When a user requests arbitrary content or wants to store, delete, or schedule content in a remote digital recorder, a corresponding service may be requested through a user interface. This is as follows.

The user accesses an open service application server through a user interface of the user terminal, logs in to a customized broadcast service, requests a service, and generates related information as metadata through a metadata generator (401). Thereafter, the metadata generated through the metadata transceiver is transmitted to the metadata transceiver of the open service application server (402).

The open service application server receives the metadata through the metadata transceiver, and parses the metadata received by the metadata transceiver through the metadata parser (403). Thereafter, the open service application server transmits the parsed request through the service request unit to the service request receiver of the open service gateway (404).

The open service gateway receives the service request through the service request receiver and processes the service received by the service request receiver through the service processor (405). The open service gateway then delivers the processed service to the headend via the service acquisition unit (406).

When the headend receives a service request from an open service gateway, it forwards the request service to a remote digital recorder according to the request service. The headend also delivers the received content to the remote digital recorder (407).

The remote digital recorder receives the content through the content receiving unit and processes the content received through the content processing unit (408). If the user requests to view the content stored in the remote digital recorder, the content is transmitted to the content receiver of the user terminal through the content transmitter (409).

When the user terminal receives the content through the content receiving unit, the user terminal decodes the content received through the content decoding unit to display on the screen. Thereafter, the user terminal renders the decoded content through the content rendering unit (410), and outputs the rendered content through the user interface.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the drawings.

As described above, the present invention can easily request customized broadcast processing even if only the open interface provided by the network operator in processing the customized broadcast function requested by the application server, and personalized broadcast service providers provide various new application services. can do. Moreover, the user information is only disclosed to the application service provider, and since only a part of the user's information is passed as a parameter to the electronic program guide and the remote digital recorder, the electronic program guide and the remote digital recorder faithfully provide a basic service and based on the application service. Providers can create profitable services.
