A revision of the original definition [1] Relative time units Relative time units define time intervals for media navigation which may be preset, user configurable, and/or automatically calculated based upon media duration. When interacting with a time-based media presentation, a user may find it beneficial to move forward or backward via a time interval relative to their current position. For example, a user may find a concept unclear in a video lecture and elect to skip back 30 seconds from the current position to review what had been described.
