Abstract
Systems and methods of providing enhanced digital media playback through application enhancement tracks are described. Application enhancement tracks are derived from the main content that they are associated with and are encoded to aid the performance of one or more functions related to the content, such as visual-search using a video application enhancement track, or trick-play track. In several embodiments, a method of decoding a media file for play back includes obtaining a media file containing compressed content and an accompanying application enhancement track which is a subset of the compressed content, playing back the compressed content, and decoding frames of the application enhancement track at a rate proportional to a visual-search speed and from a location determined by the portion of the compressed content most recently played back.
