Abstract

An apparatus and method capable of purchasing external charged content in a UPnP network are provided. A media server (MS) provides a media renderer (MR) with a URL that executes a CGI that that performs purchasing of a charged content included in an external server, and, if the MR requests the reproduction of content corresponding to the URL, the MS executes a CGI of the URL, purchases charged content corresponding to the URL, and downloads the charged content, thereby browsing a list of contents provided by an external contents purchase site through a consumer electronic device such as a digital television, in which a UPnP audio/visual control point is mounted without a separate interface, purchasing desired content, and reproducing the purchased content.

Claims

1. A method for a content directory server (CDS) to provide content in a Universal Plug and Play (UPnP) network, the method comprising:

storing a user'"'"'s log-in ID and password in a user information management unit section of the CDS;

receiving, by the CDS, a first request for content from a control point;

transmitting, by the CDS, at least a first uniform resource locator (URL) and a second URL associated with the content, wherein the first URL comprises a URL for a common gate interface (CGI), and the second URL comprises a content sample URL;

receiving, by the CDS, a second request for the content comprising one of the first URL and the second URL from a media rendering device;

determining, by the CDS, based on the URL of the second request for the content, whether the content is stored in the CDS; and

based on the determining, performing, by the media server, steps comprising;

executing the CGI of the URL of the second request for the content;

obtaining the user'"'"'s log-in ID and password from the user information management unit section;

performing an authentication at a content purchase site using the log-in and password, and

receiving the content from the content purchase site and transmitting the content to the media rendering device.

2. The method of claim 1, wherein the URL is included in a tag of the response message.

3. The method of claim 1, wherein, in the performing the process of purchasing the charged content, user information for authenticating membership of a user is transmitted to the external server to pay for the charged content using reserved points of the user.

4. The method of claim 1, wherein the receiving the purchased charged content comprises transmitting a message indicating a receipt procedure of the charged content to the media renderer,

wherein the message has a format to be reproduced by the media renderer.

5. The method of claim 1, further comprising if the performing the process of purchasing the charged content cannot be carried out, transmitting an error message to the media renderer,

wherein the error message has a format to be reproduced by the media renderer.

6. A non-transitory computer readable recording medium having embodied thereon computer program instructions that when executed by a content directory server (CDS), cause the CDS to perform a method comprising:

storing a user'"'"'s log-in ID and password in a user information management unit section of the CDS;

receiving, by the CDS, a first request for content from a control point;

transmitting, by the CDS, at least a first uniform resource locator (URL) and a second URL associated with the content, wherein the first URL comprises a URL for a common gate interface (CGI), and the second URL comprises a content sample URL;

receiving, by the CDS, a second request for the content comprising one of the first URL and the second URL from a media rendering device;

determining, by the CDS, based on the URL of the second request for the content, whether the content is stored in the CDS;

based on the determining, performing, by the media server, steps comprising;

executing the CGI of the URL of the second request for the content;

obtaining the user'"'"'s log-in ID and password from the user information management unit section;

performing an authentication at a content purchase site using the log-in and password, and

receiving the content from the content purchase site and transmitting the content to the media rendering device.

7. An apparatus for obtaining an external content in a Universal Plug and Play network, the apparatus comprising:

a common gate interface module which performs a process of purchasing charged content existing in an external server using a common gate interface based on a request from a media renderer to transmit the charged content; and

a content receiver which receives the charged content which is purchased from the external server.

8. The apparatus of claim 7, further comprising:

a uniform resource locator (URL) providing unit which provides a control point with a URL that triggers the common gate interface,

wherein the common gate interface module receives a call message including the URL from the media renderer as the request for transmission of the charged content.

9. The apparatus of claim 8, wherein the URL providing unit provides the URL included in a response message to the control point in response to a call of the control point.

10. The apparatus of claim 9, wherein the URL is included in a tag of the response message.

11. The apparatus of claim 7, wherein the common gate interface module transmits a user information for authenticating membership of a user to the external server in order to pay for the charged content using reserved points of the user.

12. The apparatus of claim 7, wherein the content receiving unit transmits a message indicating a receipt procedure of the charged content to the media renderer, wherein the message has a format to be reproduced by the media renderer.

13. The apparatus of claim 7, wherein if the common gate interface module cannot perform the process of purchasing the charged content, the common gate interface module transmits an error message to the media renderer,

wherein the error message has a format to be reproduced by the media renderer.
