Abstract
A method and computing device for determining the location of a point of interest in a media stream. The method receives an order of duplication for a media stream and a sequence of caption data strings associated with the media stream. The method computes a hash value for a selected string in the sequence. The hash value representing the selected string, and a number of strings in the sequence that immediately precede the selected string, where the order of duplication determines the number of strings. The method receives a media stream time for the selected string based on the hash value, and determines a time at a point of interest in the media stream relative to the media stream time for the selected string.
