Claim 17:
18. A method of processing media content comprising video content and associated audio content, the method comprising:
receiving the video content and the associated audio content;
analyzing the associated audio content by applying speech detection to the audio content;
determining, based on the analysis, one or more navigation points for enabling navigation of the media content, the one or more navigation points indicating starting points of spoken utterances in the associated audio content for short-term rewinding;
embedding the one or more navigation points into metadata for the media content;
outputting the video content, the associated audio content, and the metadata;
providing a visual representation of a scan bar, wherein the scan bar includes a first portion and a second portion having the same length, wherein the first portion corresponds to a first time length of video content and the second portion corresponds to a second time length of video content longer than the first time length, and wherein the first time length and the second time length are based at least in part on the density of the one or more navigation points over time;
in response to a user instruction instructing short-term rewinding of the media content to replay the media content from one of the one or more navigation points, modifying the media content starting at the one of the one or more navigation points for replaying the media content with improved intelligibility of the associated audio content, wherein the modifying comprises performing dialog enhancement to boost and clarify a dialog;
pausing, during replaying of the media content as modified, playback of the media content;
resuming, after pausing, playback of the media content as modified starting at the one of the one or more navigation points for replaying the media content; and
in response to reaching a subsequent navigation point during replaying of the media content as modified, fading out the dialog enhancement.
