Abstract
Generation of live streaming indices is disclosed that stores a media stream recording from a live event. Seek points are added to a fixed-length index memory corresponding to each point of the media stream separated at a first interval. In response to the fixed length being reached, alternate ones of the seek points are deleted up to a predefined percentage of the fixed length. Location indicators are added where the deletions caused the previous interval to be altered and at the end of the previous seek points remaining in the index memory. A new interval is then calculated, which corresponds to the altered interval, after which new seek points are added beginning at the second location indicator to the index memory corresponding to the points in the media stream separated by the new interval.
