Abstract

A system that stores plural reference measures, each reference measure corresponding to measured transitions of one or more video objects of plural successive pictures corresponding to a video scene, receives first and second measures of plural successive pictures corresponding to a first video scene received from a remote device, the first and second measures corresponding to measured transitions of a video object of the first video scene, compares the first and second measures with the stored plural reference measures, and indicates to the remote device whether a threshold percentage match exists between the first and second measures and one of the stored plural reference pictures.

Claims

1. A system, comprising:

a data structure configured to store plural reference measures, each reference measure corresponding to measured transitions of one or more video objects of plural successive pictures corresponding to a video scene;

a memory with logic stored therein; and

a processor configured to execute the logic to;

receive a first measure of plural successive pictures corresponding to a first video scene received from a remote device, the first measure corresponding to measured transitions of a video object of the first video scene;

compare the first measure with the stored plural reference measures; and

provide an indication to the remote device whether a match exists between the first measure and one of the stored plural reference pictures.

2. The system of claim 1, wherein the data structure comprises a database indexed with keys that comprise video content parameters.

3. The system of claim 2, wherein the video content parameters comprise one or more of a video content identifier and a scene number.

4. The system of claim 2, wherein the keys include subcategory indexes within which the reference measures are categorized.

5. The system of claim 4, wherein the subcategory indexes include one or more of a range of video objects.

6. The system of claim 4, wherein the subcategory indexes include one or more of dimensionality between video objects at a time corresponding to a first measurement and dimensionality of video objects at a time corresponding to a second measurement.

7. The system of claim 4, wherein the subcategory indexes include one or more of an area of video objects at a time corresponding to a first measurement and an area of video objects at a time corresponding to a second measurement.

8. The system of claim 4, wherein the subcategory indexes include one or more of video snippet time length, time stamps, an indication of whether the video object disappears, and an indication of whether the video object has a duration over a defined window of time or number of frames.

9. The system of claim 4, wherein the subcategory indexes include one or more of percentage increase of the video object and a percentage decrease of the video object.

10. The system of claim 1, wherein the processor is further configured to execute the logic to receive an identification of one or more of the first video scene and video content the comprises the first video scene, the identification associating the first measure with the one or more of the first video scene and the video content.

11. The system of claim 1, wherein the processor is further configured to execute the logic to determine the match exists when at least a defined threshold percentage match exists.

12. The system of claim 11, wherein the defined threshold percentage match is less than one hundred percent.

13. The system of claim 1, wherein the processor is further configured to execute the logic to provide an indication of a match based on reception of plural measures that include the first measure from plural successive video scenes that include the first video scene.

14. The system of claim 13, wherein the processor is further configured to execute the logic to determine there exists a match between plural reference measures corresponding to plural successive reference video scenes and the received plural measures when there is at least a defined threshold percentage match.

15. The system of claim 14, wherein the defined threshold percentage match is less than one hundred percent.

16. The system of claim 1, wherein the processor is further configured to execute the logic to determine the match exists based on validating a first match, wherein the processor is further configured to execute the logic to validate the first match based on a comparison between the first measure and the plural reference measures of one or more of color planes and voice tracks.

17. The system of claim 1, wherein each of the plural reference measures include first and second measures, the first measure corresponding to a first version of a video sequence and the second measure corresponding to the first version less a defined number of pictures.

18. A method, comprising:

storing plural reference measures, each reference measure corresponding to measured transitions of one or more video objects of plural successive pictures corresponding to a video scene;

receiving first and second measures of plural successive pictures corresponding to a first video scene received from a remote device, the first and second measures corresponding to measured transitions of a video object of the first video scene;

comparing the first and second measures with the stored plural reference measures; and

indicating to the remote device whether a threshold percentage match exists between the first and second measures and one of the stored plural reference pictures.

19. The method of claim 18, wherein comparing further comprises determining the existence of a match based on a threshold percentage match less than one hundred percent.

20. A system, comprising:

means for storing plural reference measures, each reference measure corresponding to measured transitions of one or more video objects of plural successive pictures corresponding to a video scene;

means for receiving a first measure of plural successive pictures corresponding to a first video scene received from a remote device, the first measure corresponding to measured transitions of a video object of the first video scene;

means for comparing the first measure with the stored plural reference measures; and

means for indicating to the remote device whether a threshold percentage match of less than or equal to one hundred percent exists between the first measure and one of the stored plural reference pictures.
