Abstract
A system and method of detecting unidentified broadcast electronic media content using a self-similarity technique is presented. The process and system catalogues repeated instances of content that has not be positively identified, but are sufficiently similar as to infer repetitive broadcasts. These catalogued instances may be further processed on the basis of different broadcast channels, sources, geographic locations of broadcasts or format to further assist the identification thereof.

18. A method executed by a digital signal processing system for detecting self-similar repetition in a broadcast signal comprising:
detecting a thread comprising a sequence of one or more portions of a first unregistered piece of programming, where each consecutive portion of the first unregistered piece is determined to be sufficiently similar to a corresponding substantially consecutive portion of a second unregistered piece of unregistered programming. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

30. A method executed by a digital signal processing system for detecting self-similar repetition in a broadcast signal comprising:
detecting insufficient self-similarities between two non-overlapping pieces of unregistered programming of a broadcast signal by determining the number of pairs of insufficiently self-similar corresponding portions from each of the two pieces of unregistered programming, wherein said pairs of insufficiently self-similar corresponding portions substantially succeed a substantial number of substantially consecutive pairs of sufficiently self-similar corresponding portions. - View Dependent Claims (31, 32, 33, 34, 36, 37, 38, 39, 40)

41. A digital signal processing system for detecting at least two substantially similar instances of the same piece of unregistered program in one or more broadcast signals comprising:
a detection means adapted for periodically detecting whether two or more unregistered portions of said one or more broadcast signals is sufficiently self-similar. - View Dependent Claims (44, 45, 46, 47, 48, 49, 50)
- 42. The system of claim 42, wherein said detection means is further adapted for detecting one or more sufficiently similar sets of pattern vectors, wherein each set corresponds to one of the one or more unregistered portions.

52. A digital signal processing system for detecting self-similar repetition in a broadcast signal comprising:
a detection means adapted for detecting a thread comprising a sequence of one or more portions of a first unregistered piece of programming, where each consecutive portion of the first unregistered piece is determined to be sufficiently similar to a corresponding substantially consecutive portion in a second unregistered piece of unregistered programming. - View Dependent Claims (53, 54)

55. A digital signal processing system for detecting self-similar repetition in a broadcast signal comprising:
detection means adapted for detecting insufficient self-similarities between two non-overlapping pieces of unregistered programming of a broadcast signal by determining the number of pairs of insufficiently self-similar corresponding portions from each of the two pieces of unregistered programming, wherein said pairs of insufficiently self-similar corresponding portions substantially succeed a substantial number of substantially consecutive pairs of sufficiently self-similar corresponding portions. - View Dependent Claims (56, 57, 58, 59)
