Abstract

A digital content distribution system and method is disclosed. The system includes a media server (20) arranged to provide a virtual digital content repository (25), the virtual digital media content repository (25) comprising local digital media content (26) and remote digital media content (45), local digital media content (26) being media content that is locally accessible to the media server (20) and remote digital media content (45) being media content that is remotely accessible to said media server from a remote source (40) and is subject to authentication, wherein the media server (20) is arranged to serve media content from the virtual digital content repository (25) on request to one or more client systems (30), upon request of remote digital media content (45), the media server (20) being arranged to authenticate with said remote source (40), obtain data on said requested remote digital media content (45) from the remote source (40) and serve the remote digital media content (45) to the requesting client system (30).

Claims

1. A digital content distribution system including:

a media server arranged to provide a virtual digital content repository, the virtual digital media content repository comprising local digital media content and remote digital media content, local digital media content being media content that is locally accessible to the media server and remote digital media content being media content that is remotely accessible to said media server from a remote source and is subject to authentication, wherein the media server is arranged to serve media content from the virtual digital content repository on request to one or more client systems, upon request of remote digital media content, the media server being arranged to authenticate with said remote source, obtain data on said requested remote digital media content from the remote source and serve the remote digital media content to the requesting client system.

2. A digital content distribution system according to claim 1, wherein the media server is arranged to present the virtual digital media content repository as comprising content available locally, the media server being arranged to perform said authentication and obtaining of data on remote media content data transparently to said requesting client system.

3. A digital content distribution system according to claim 1, wherein the media server comprises a Universal plug and play, UPnP, handler that is arranged to serve media content from the virtual digital content repository on request to said one or more client systems.

4. A digital content distribution system according to claim 1, wherein said remote source is a further media server arranged to serve local digital media content to said media server or direct to said requesting client system upon authentication of a request from the media server.

5. A digital content distribution system according to claim 1, further comprising a tracker system arranged to communicate with the or each media server, wherein the or each media server is arranged to periodically provide data to said tracker system, said data including a network address at which the media server is contactable.

6. A digital content distribution system according to claim 5, wherein the or each media server is arranged to provide data to said tracker system on systems or users to be permitted access to local digital media content, for each local user or system the or each media server being arranged to periodically obtain data from the tracker system on other media servers that the local user or system is designated as being permitted access to and to update said virtual digital media repository in dependence on said obtained data.

7. A digital content distribution system according to claim 4, wherein the media server is arranged to communicate with said further media server by adding access credentials to an UPnP request received from said client system, inserting the modified UPnP request within an HTTP communication and passing the HTTP communication to the further media server, the further media server being arranged to extract the modified UPnP request from the HTTP communication and, subject to authentication using said access credentials, process said UPnP request as a conventional UPnP request.

8. A digital content distribution system according to claim 1, comprising a plurality of media servers, each being remote of each other and each being arranged, subject to authentication according to predefined access credentials, to serve local digital media content to one or more others of the plurality of media servers.

9. A digital content distribution method including:

providing a virtual digital content repository at a media server, the virtual digital media content repository referencing local digital media content and remote digital media content, local digital media content being media content that is locally accessible to the media server and remote digital media content being media content that is remotely accessible to said media server from a remote source and is subject to authentication;

serving media content from the virtual digital content repository on request to one or more client systems; and

,

upon request for remote digital media content referenced in the virtual digital media repository, causing the media server to authenticate with said remote source, obtain data on said requested remote digital media content from the remote source and serve the remote digital media content to the requesting client system.

10. A digital content distribution method according to claim 9, further comprising:

presenting the virtual digital media content repository as comprising content available locally; and

,

performing said authentication and obtaining of data on remote media content data transparently to said requesting client system.

11. A digital content distribution method according to claim 9, wherein said remote source is a further media server, the method further comprising:

serving local digital media content from said further media server to said media server or direct to said requesting client system upon authentication of a request from the media server.

12. A digital content distribution method system according to claim 9, further comprising providing a tracker system arranged to communicate with the or each media server, and periodically providing data from the or each media server to said tracker system, said data including a network address at which the respective media server is contactable.

13. A digital content distribution method according to claim 12, further comprising providing data from the or each media server to said tracker system on systems or users to be permitted access to local digital media content,

the or each media server periodically obtaining, for each local user or system, data from the tracker system on other media servers that the local user or system is designated as being permitted access to;

and,

updating the virtual digital media repository of the respective media server in dependence on said obtained data.

14. A digital content distribution method according to claim 11, wherein the method further comprises:

communicate between the media server and the further media server by adding access credentials to a UPnP request received from said client system;

inserting the modified UPnP request within an HTTP communication and passing the HTTP communication to the further media server,

extracting the modified UPnP request at the further media server from the HTTP communication; and

,

subject to authentication using said access credentials, processing said UPnP request at the further media server as a conventional UPnP request.

15. A digital content distribution system according to claim 9, further comprising operating a plurality of media servers, each being remote of each other and each being arranged, subject to authentication according to predefined access credentials, to serve local digital media content to one or more others of the plurality of media servers.
