Abstract

An automatic metadata generation service system for use in home networks includes a home network interface adapted to perceive user network activity on a home network. A metadata generation service module generates user metadata based on the user network activity. An update service module automatically updates one or more existing metadata sets on the home network with generated metadata. In other aspects, a metadata generation service system for use with a home network, includes a home network interface adapted to interact with one or more of content providers or service providers according to one or more service discovery protocols. A monitoring service module obtains an update of metadata from one or more of the providers. A metadata generation service module convert metadata of one format received via the update to metadata of another format required by the home network.

Claims

1. An automatic metadata generation service system for use in home networks, the system comprising:

a home network interface adapted to perceive user network activity on a home network;

a metadata generation service module generating user metadata based on the user network activity;

an update service module automatically updating one or more existing metadata sets on the home network with generated metadata.

2. The system of claim 1, wherein said metadata generation service module generates user metadata based on user content viewing activity.

3. The system of claim 1, wherein said metadata generation service module generates content segmentation metadata based on user playback activity.

4. The system of claim 1, wherein said metadata generation service module generates user metadata based on user rendering preferences.

5. The system of claim 1, wherein said metadata generation service module generates user metadata based on control traffic corresponding to user voice command.

6. The system of claim 1, wherein said metadata generation service module generates user metadata based on content directory service (CDS) interaction with control points (CP).

7. The system of claim 1, further comprising a monitoring service module automatically performing an analysis of content and generating content metadata based on the analysis.

8. The system of claim 7, wherein said monitoring service module generates content metadata based on content stream segmentation.

9. The system of claim 7, wherein said monitoring service module generates content metadata based on parsed contents of textual descriptions contained in the content stream, wherein the descriptions describe media contents contained in the content stream.

10. The system of claim 7, wherein said monitoring service module generates content metadata based on closed captions contained in the content stream of stored content.

11. The system of claim 7, wherein said monitoring service module generates content metadata based on subtitles contained in the content stream.

12. The system of claim 7, wherein said monitoring service module generates content metadata based on predefined metadata contained in the content stream.

13. A metadata generation service system for use with a home network, comprising:

a home network interface adapted to interact with one or more of content providers or service providers according to one or more service discovery protocols;

a monitoring service module adapted to obtain an update of metadata from one or more of said providers; and

a metadata generation service module adapted to convert metadata of one format received via the update to metadata of another format required by the home network.

14. The system of claim 13, wherein said monitoring service module is adapted to subscribe to a control/metadata event change notification from one or more of said providers, consequently receiving said update.

15. The system of claim 13, further comprising an update service module adapted to update a set of metadata on the home network when the update becomes available.

16. The system of claim 15, wherein said update service module is adapted to communicate the metadata to one or more of said providers.

17. The system of claim 15, wherein said update service module is adapted to update user profiles related to users of the home network.

18. The system of claim 17, wherein said update service module updates a user profile of a user by recording a number of times the user consumed a particular portion of content.

19. The system of claim 17, wherein said update service module is adapted to dynamically update categories of content in the user profiles as new categories are revealed in the metadata.

20. The system of claim 13, wherein said metadata generation service module is further adapted to generate user metadata based on user network activity.

21. The system of claim 20, wherein said metadata generation service module generates user metadata based on user content viewing activity.

22. The system of claim 20, wherein said metadata generation service module generates content segmentation metadata based on user playback activity.

23. The system of claim 20, wherein said metadata generation service module generates user metadata and content metadata based on user rendering preferences.

24. The system of claim 20, wherein said metadata generation service module generates user metadata and content metadata based on control traffic corresponding to user voice command.

25. The system of claim 20, wherein said metadata generation service module generates user metadata and content metadata based on content directory service (CDS) interaction with control points (CP).
