Patent ID: 8020084

Claim:
A method for determining a first and a second total elapsed play time of an interactive multimedia presentation having a play duration, a video content component and an interactive content component, the method comprising: identifying a first time interval within the play duration, in which the video content component is not scheduled for presentation during the first time interval; based on a first timing signal, measuring a first elapsed play time of the interactive multimedia presentation that occurs within the first time interval; for play of the interactive multimedia presentation that occurs within the first time interval, determining the first total elapsed play time using the first elapsed play time; identifying a second time interval within the play duration, in which the video content component is scheduled for presentation during the second time interval; based on a second timing signal, measuring a second elapsed play time of the interactive multimedia presentation that occurs within the second time interval; and for play of the interactive multimedia presentation that occurs within the second time interval, determining the second total elapsed play time using the second elapsed play time, wherein the first timing signal is a continuous timing signal, unaffected by the play speed of the video content component, and the second timing signal coordinates a rate at which the video content component is received from the video source, the rate based on the play speed of the interactive multimedia presentation.
