Abstract

Methods and systems for determining a total elapsed play time (409) of an interactive multimedia presentation (120/127) having a play duration (292), a video content component (122), and an interactive content component (124) include identifying two time intervals within the play duration. During the first interval (297), no video is scheduled for presentation, and a first elapsed play time of the presentation is measured based on a first timing signal (401). During the second interval, a video (which may include video, audio, data, or any combination thereof) is scheduled for presentation, and a second elapsed play time is measured based on a second timing signal (471). During the first interval, total elapsed play time (409) is determined using the first elapsed play time, and during the second interval, it is determined using the second elapsed play time. The total elapsed play time (409) is usable to provide frame-accurate synchronization between the interactive content component (124) and the video content component (122).
