Abstract:
The present invention relates to an advertisement detection system based on fingerprints, and provides an advertisement detection systems based on fingerprints, including a content stream storage unit for storing broadcast content in real time, a section selection unit for selecting a reference section and a test section from broadcast content stored by the content stream storage unit, a fingerprint extraction unit for extracting fingerprints from the reference section and the test section selected by the section selection unit using one or more methods, a fingerprint matching unit for comparing the fingerprints from the test section and the reference section, extracted by the fingerprint extraction unit, with each other and then performing matching between the fingerprints, an advertisement section determination unit for determining advertisement segments from the test section based on results of the matching performed by the fingerprint matching.

Claim (Index 1):
A method for advertisement detection based on fingerprints, the method comprising:\n storing a sequence of broadcast content in real time; selecting a reference section and a test section from the stored sequence of broadcast content, wherein the selected test section and the selected reference section are respective time sections defined in relation to each other in the stored sequence of broadcast content, and wherein selecting the reference section and the test section from the stored sequence of broadcast content comprises selecting from the stored sequence of broadcast content a first time section as the test section and selecting from the same stored sequence of broadcast content a second time section, ranging from an end point of the test section, as the reference section; extracting fingerprints respectively from the selected reference section and from the selected test section, using one or more fingerprint extraction methods; comparing the extracted fingerprints from the test section with the extracted fingerprints from the reference section to perform matching between the compared fingerprints; determining an advertisement segments from the test section based on results of the matching; and storing segment information about the determined advertisement segments in an advertisement database.
