Abstract
A method of storing digital video content to facilitate trick play consistent with certain embodiments involves storing inter-coded frames of the content in a first file and storing intra-coded frames of the content in a second file. A set of forward indices are used to address the intra coded frames in a forward direction such that playback of the second file in the order of the forward indices simulates a fast-forward playback. A set of reverse indices are used to address the intra-coded frames in a reverse direction such that playback of the second file in the order of the reverse indices simulates a fast-reverse playback. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
