Abstract

The picture information of video can be used in various ways to identify the video or its topical subject matter. This enables numerous novel arrangements in which particular video of interest to a particular consumer can be discerned. A variety of other embodiments and features are also detailed.

Claims

1. A method comprising the acts:

processing a feed of video content, said feed of video content including first and second segmented objects, said processing including analyzing data representing a first object to thereby recognize same;

checking the recognized first object against a set of previously-stored reference data, said reference data relating to topical subjects of interest to a particular consumer; and

if said checking yields a particular outcome, taking an action relating to said first object.

2. The method of claim 1 wherein said processing further includes analyzing data representing a second object to thereby recognize same, and the method further includes:

checking the recognized second object against said set of reference data; and

if said checking yields a particular outcome, taking an action relating to said second object.

3. The method of claim 1 wherein said action comprises identifying a corresponding excerpt of a video program, rather than an entire video program, as being of viewing interest by said consumer.

4. The method of claim 1 wherein said processing takes places in a distribution system for said feed of video content—

at a location before said video content is delivered to an end user device.

5. The method of claim 1 wherein said analyzing comprises extracting identification data from said first object.

6. The method of claim 5 wherein said analyzing comprises discerning a digital watermark with which said first object has been encoded.

7. The method of claim 1 wherein said feed of video content comprises an MPEG-4 stream of video content.

8. The method of claim 1 wherein said action includes retrieving an earlier part of said feed from a data store.

9. The method of claim 1 wherein one of said segmented objects comprises an automobile.

10. A method comprising the acts:

receiving information from a consumer about topical subject matter of interest to said consumer;

processing a collection of video, said video including a first portion related to topical subject matter in which the consumer has expressed interest by said received information, and further including a second portion related to topical subject matter in which the consumer has not expressed interest by said received information, said first portion having an uncertain stopping or ending point within said video collection, said processing including analyzing picture information to be rendered for viewing, to identify the first portion of interest to said consumer; and

taking an action based thereon.

11. The method of claim 10 wherein said action comprises presenting said first portion for viewing by the consumer, together with part—

but not all—

of an adjoining second portion.

12. The method of claim 10 wherein said analyzing picture information comprises analyzing MPEG-4 video objects in said collection of video to recognize a video object of interest to said consumer, by reference to the received information.

13. The method of claim 12 wherein said analyzing comprises discerning identification data from said first object.

14. The method of claim 13 wherein said analyzing comprises discerning a digital watermark with which said video object of interest to said consumer has been encoded.

15. The method of claim 10 wherein said collection of video comprises a broadcast stream of video.

16. A method comprising the acts:

receiving and storing preference data for a consumer, the preference data identifying at least one topic of interest to that consumer;

processing a feed of video content earlier coded using object segmentation technology, said feed of video content depicting plural objects, said processing including analyzing data representing a first object to thereby recognize same;

checking the recognized first object against the preference data; and

if said checking yields a particular outcome, taking an action relating to said first object.

17. The method of claim 16 wherein said processing further includes analyzing data representing a second object to thereby recognize same, and the method further includes:

checking the recognized second object against the stored reference data; and

if said checking yields a particular outcome, taking an action relating to said second object.

18. The method of claim 16 wherein said action comprises identifying a corresponding excerpt of a video program, rather than an entire video program, as being of viewing interest by said consumer.

19. The method of claim 16 wherein said processing takes places in a distribution system for said feed of video content—

at a location before said video content is delivered to an end user device.

20. The method of claim 16 wherein said analyzing comprises extracting identification data from said first object.

21. The method of claim 16 wherein said analyzing comprises discerning a digital watermark with which said first object has been encoded.

22. The method of claim 16 wherein said receiving comprises receiving explicit preference information from said consumer.

23. The method of claim 16 wherein said receiving comprises inferring preference information from behavior of said consumer.
