Abstract

A video services receiver and related operating methods are disclosed here. In accordance with one disclosed methodology, the video services receiver receives a segment of video content, and processes a plurality of contiguous sub-segments of the segment of video content to generate a corresponding plurality of characterizing signatures. Each of the characterizing signatures identifies a respective one of the contiguous sub-segments. The video services receiver compares the characterizing signatures to video content signatures maintained in a database. When the results of the comparing satisfy predetermined matching criteria, the video services receiver initiates an operation that influences presentation attributes of the segment of video content.

Claims

1. A method of operating a video services receiver, the method comprising:

providing a first video stream for presentation to a user, the first video stream comprising a segment of video content;

processing the segment of video content to generate at least one characterizing signature that uniquely identifies the segment of video content;

using the at least one characterizing signature in a query against a database of video content signatures;

presenting the first video stream, including the segment of video content, when the query does not find the at least one characterizing signature in the database of video content signatures; and

presenting a second video stream when the query finds the at least one characterizing signature in the database of video content signatures, wherein the second video stream represents an altered version of the first video stream.

2. The method of claim 1, wherein:

the at least one characterizing signature comprises a plurality of characterizing signatures; and

each of the characterizing signatures identifies a respective sub-segment of the segment of video content.

3. The method of claim 1, wherein the processing step generates the at least one characterizing signature based on closed captioning data associated with the segment of video content.

4. The method of claim 1, wherein the processing step generates the at least one characterizing signature based on histogram data associated with the segment of video content.

5. The method of claim 1, wherein the processing step generates the at least one characterizing signature based on pixel luminance data associated with the segment of video content.

6. The method of claim 1, wherein the step of presenting the second video stream comprises:

replacing at least a portion of the segment of video content with a segment of alternative video content.

7. The method of claim 1, wherein the step of presenting the second video stream comprises:

removing at least a portion of the segment of video content from the first video stream.

8. The method of claim 1, further comprising:

populating the database of video content signatures with entries corresponding to segments of video content.

9. The method of claim 8, wherein the flagged segments of video content represent advertisements or commercials.

10. A method of operating a video services receiver, the method comprising:

receiving a segment of video content;

processing a plurality of contiguous sub-segments of the segment of video content to generate a corresponding plurality of characterizing signatures, wherein each of the characterizing signatures identifies a respective one of the contiguous sub-segments;

comparing the characterizing signatures to video content signatures maintained in a database; and

when results of the comparing satisfy predetermined matching criteria, initiating an operation that influences presentation attributes of the segment of video content.

11. The method of claim 10, wherein, when results of the comparing satisfy the predetermined matching criteria, the video services receiver replaces at least a portion of the segment of video content with a segment of alternative video content.

12. The method of claim 10, wherein, when results of the comparing satisfy the predetermined matching criteria, the video services receiver skips at least a portion of the segment of video content.

13. The method of claim 10, further comprising:

populating the database with entries corresponding to flagged segments of video content.

14. The method of claim 13, wherein the flagged segments of video content represent advertisements or commercials.

15. The method of claim 10, further comprising:

providing the segment of video content to a presentation device, wherein the processing and comparing steps are performed concurrently with the providing step.

16. A video services receiver comprising:

a receiver interface to receive data associated with video services, including a first video stream comprising a segment of video content;

a display interface for a display operatively coupled to the video services receiver, the display interface facilitating presentation video streams on the display; and

a processor coupled to the receiver interface and the display interface, wherein the processor generates at least one characterizing signature that identifies the segment of video content, compares the at least one characterizing signature against video content signatures maintained in a database to obtain comparison results, and initiates an operation that influences presentation attributes of the first video stream when the comparison results satisfy predetermined matching criteria.

17. The video services receiver of claim 16, wherein the database resides at the video services receiver.

18. The video services receiver of claim 16, wherein:

when the comparison results satisfy the predetermined matching criteria, the processor replaces at least a portion of the segment of video content with a segment of alternative video content, resulting in a second video stream that contains the alternative video content; and

the display interface facilitates presentation of the second video stream on the display.

19. The video services receiver of claim 16, wherein the database is populated with entries corresponding to flagged segments of video content.

20. The video services receiver of claim 19, wherein the flagged segments of video content represent advertisements or commercials.
