Abstract
Methods and apparatus are provided for automatically removing erroneously logged commercials from a listing of commercials that are detected in a video data stream by performing automatic content recognition on the video data stream and detecting the identity of each of the commercials played in a commercial break, temporarily logging the identity and start and end time of each detected commercial in a log of played commercials, forming clusters from commercials that overlap in time and have related content, or have significant overlap in time, forming permutations of commercial break timelines from the detected commercials, ranking the timelines based on best fit criteria and selecting the best fit timeline, permanently logging only the commercials in the best fit timeline, and removing the remaining commercials from the temporary log. The remaining logged commercials are presumed to be either erroneously identified commercials or properly identified commercials with erroneous start and end times.
