Abstract

A system and method is provided to automatically generate content for ITV products and services by processing primary media sources. In one embodiment of the invention, keywords are automatically extracted from the primary media sources using one or more of a variety of techniques directed to video, audio and/or textual content of the multimodal source. In some embodiments, keywords are then processed according to one or more disclosed algorithms to narrow the quantity of downstream processing that is necessary to associate secondary sources (reference items) with the primary video source. Embodiments of the invention also provide automatic searching methods for the identification of reference items based on the processed keywords in order to maximize the value added by the association of reference items to the video source.

Claims

1. A method for generating interactive television content, comprising:

determining a first plurality of keywords from a portion of a media source;

selecting a second plurality of keywords from the first plurality of keywords, wherein the selecting the second plurality of keywords comprises scoring each of the first plurality of keywords based on a type of collection process that automatically determined each of the corresponding first plurality of keywords, wherein a first type of collection process is scored higher than a second type of collection process, wherein the second plurality of keywords is determined based upon one or more of the first plurality of keywords that have a score above a predetermined threshold;

searching a memory to identify a plurality of reference items related to the media source based upon the second plurality of keywords, wherein the plurality of reference items is external to the media source;

embedding the plurality of reference items into the media source; and

delivering the media source embedded with the plurality of reference items to a customer premises.

2. The method of claim 1, wherein the determining the first plurality of keywords comprises:

determining whether the media source includes a closed caption text;

decoding the closed caption text if the media source includes the closed caption text; and

extracting audio and performing a speech-to-text conversion on the extracted audio if the media source does not include closed caption text.

3. The method of claim 1, wherein the determining the first plurality of keywords comprises performing an on-screen text recognition.

4. The method of claim 1, wherein the determining the first plurality of keywords comprises performing a shape analysis on a video frame of the media source.

5. The method of claim 1, wherein the determining the first plurality of keywords comprises:

detecting a face on a video frame of the media source; and

performing a face recognition on the face.

6. The method of claim 1, wherein the searching the memory is performed for each of the first plurality of keywords.

7. The method of claim 6, wherein the searching the memory comprises:

querying a news clip directory where a keyword from the first plurality of keywords is related to current events; and

querying an encyclopedia where the keyword from the first plurality of keywords is not related to current events.

8. The method of claim 6, wherein the searching the memory comprises:

querying a primary reference list; and

querying a secondary reference list if a quantity of the plurality of reference items does not exceed a predetermined threshold value.

9. The method of claim 1, wherein the searching the memory is performed for each of the second plurality of keywords.

10. The method of claim 9, wherein the searching the memory comprises:

querying a news clip directory where a keyword from the second plurality of keywords is related to current events; and

querying an encyclopedia where the keyword from the second plurality of keywords is not related to current events.

11. The method of claim 9, wherein the searching the memory comprises:

querying a primary reference list; and

querying a secondary reference list if a quantity of the plurality of reference items does not exceed a predetermined threshold value.

12. A system for generating interactive television content, comprising:

means for determining a first plurality of keywords from a portion of a media source;

means for selecting a second plurality of keywords from the first plurality of keywords, wherein the selecting the second plurality of keywords comprises scoring each of the first plurality of keywords based on a type of collection process that automatically determined each of the corresponding first plurality of keywords, wherein a first type of collection process is scored higher than a second type of collection process, wherein the second plurality of keywords is determined based upon one or more of the first plurality of keywords that have a score above a predetermined threshold;

means for searching a memory to identify a plurality of reference items related to the media source based upon the second plurality of keywords, wherein the plurality of reference items are external to the media source;

means for embedding the plurality of reference items into the media source; and

means for delivering the media source embedded with the plurality of reference items to a customer premises.

13. The system for generating interactive television content of claim 12, wherein the means for determining the first plurality of keywords determines whether the media source includes a closed caption text, decodes the closed caption text if the media source includes the closed caption text and extracts audio and performing a speech-to-text conversion on the extracted audio if the media source does not include closed caption text.

14. The system for generating interactive television content of claim 12, wherein the means for determining the first plurality of keywords comprises performing an on-screen text recognition.

15. The system for generating interactive television content of claim 12, wherein the means for determining the first plurality of keywords comprises performing a shape analysis on a video frame of the media source.

16. The system for generating interactive television content of claim 12, wherein the means for determining the first plurality of keywords detects a face on a video frame of the media source and performs a face recognition on the face.

17. The system for generating interactive television content of claim 12, wherein the means for searching the memory queries a news clip directory where a keyword from the first plurality of keywords is related to current events, and queries an encyclopedia where the keyword from the first plurality of keywords is not related to current events.

18. A system for generating interactive television content, comprising:

an interface to a media source;

an interface to a database, the database having a list of reference items, wherein the reference items are external to the media source; and

an application server coupled to the interface to the database and the interface to the media source, the application server configured to determine a plurality of first key words from a portion of the media source, to select a second plurality of keywords from the first plurality of keywords, wherein the selecting the second plurality of keywords comprises scoring each of the first plurality of keywords based on a type of collection process that determined each of the corresponding first plurality of keywords, wherein a first type of collection process is always scored higher than a second type of collection process, wherein the second plurality of keywords is determined based upon one or more of the first plurality of keywords that have a score above a predetermined threshold, to search the database to identify a plurality of reference items related to the media source based upon the second plurality of keywords, to embed the plurality of reference items into the media source, to deliver the media source embedded with the plurality of reference items to a customer premises.

19. The system of claim 18, wherein the media source includes video information.

20. The system of claim 18, wherein the application server is further configured to search for a reference item using the plurality of second keywords.
