Video entity recognition in compressed digital video streams
First Claim
Patent Images
1. A method of detecting a video entity in a media stream, the method comprising:
- receiving a first media stream comprising a plurality of video frames and including at least one known video entity;
compressing the first media stream, the compressing comprising automatically generating a first fingerprint of statistical parameters of at least a portion of the first media stream; and
submitting the first fingerprint and at least one item of identification information corresponding to the first media stream to a database of fingerprints of known media content.

Abstract
A method and system for detection of video segments in compressed digital video streams is presented. The compressed digital video stream is examine to determine synchronization points, and the compressed video signal is analyzed following detection of the synchronization points to create video fingerprints that are subsequently compared against a library of stored fingerprints.

12. A method of detecting a video entity in a media stream, the method comprising:
-
receiving a first media streams comprising a plurality of video frames and a known video entity; compressing the first media stream, the compressing comprising automatically generating a first fingerprint of statistical parameters of at least a portion the first media stream; storing the first fingerprint of the first media stream; receiving a second media stream having unidentified content and at least one item of identification information corresponding to the second media stream; generating a second fingerprint of at least a portion of the second media stream; comparing the second fingerprint to a plurality of stored fingerprints, the plurality of stored fingerprints including the first fingerprint; and determining, based on the comparing, whether the second media stream contains at least one known video entity. - View Dependent Claims (13, 14, 15)

16. A computer program product, comprising a computer usable, non-transitory medium having a computer readable program code embodied therein, said computer readable program code adapted to be executed to implement a method detecting a video entity in a video stream having a plurality of video frames, said method comprising:
-
storing a plurality of known fingerprints, wherein each of the known fingerprints includes a calculated feature corresponding to at least one frame of known video content; receiving the video stream; defining a plurality of regions of interest in the video frames of the received video stream; determining a fingerprint of at least one of the video frames based on the defined regions of interest; comparing the determined fingerprint to the plurality of known fingerprints; and determining, based on the comparing, that the received video stream contains the video entity. - View Dependent Claims (17, 18, 19)
