Video stream modification to defeat detection
First Claim
Patent Images
1. A method for altering a video stream to prevent the detection of video segments comprising:
- receiving a video stream;
altering at least one of the set of features and statistical parameters associated with the video stream wherein the altering reduces the ability to detect a video segment in the video stream.

Abstract
A method and system for detecting automatic ad detection is presented in which video streams are modified such that features cannot be automatically recognized or statistical parameters and fingerprints derived from the video stream cannot be matched against fingerprints of known video segments in a database.

7. A system for altering a video stream to prevent the detection of a video segment comprising:
-
a detection subsystem for detecting parameters associated with the video stream and indicative of the presence of the video segment;
a modification subsystem for modifying the video stream to prevent detection of the presence of the video segment. - View Dependent Claims (8, 9, 10)

- 11. A method for altering a video stream to prevent the detection of video segments comprising altering the video stream to produce a modified video stream wherein the altering substantially increases the dissimilarity between a video segment fingerprint derived from the video stream and a stored fingerprint representing the video segment.

20. An apparatus for altering a video stream to prevent detection of a video segment comprising:
-
a receiver for receiving a video stream;
a processor for detecting at least one parameter of the video stream capable of being used for detection of the video segment and for altering the at least one parameter of the video stream to prevent detection of the video segment. - View Dependent Claims (21)

- 22. A method for preventing automated advertisement detection of at least one advertisement in a video stream comprising, altering at least one of the sets of features and statistical parameters associated with the video stream surrounding the at least one advertisement, wherein the altering causes a sufficient increase in the similarity between the video stream and the advertisement to render automated advertisement detection ineffective.
