Patent ID: 8068108

Claim:
A method, performed by at least one machine, for use in a rendering system for rendering temporal sequence presentation data in a machine-implemented rendering system, the temporal sequence presentation data being tangibly stored in a first computer-readable medium, the method comprising steps of: (A) maintaining a value of a presentation time parameter tangibly stored in a second computer-readable medium and representing an amount of time elapsed during rendering of a portion of the temporal sequence presentation data; (B) maintaining a value of a data time parameter tangibly stored in a third computer-readable medium and representing an amount of time required by the rendering system to render the portion of the temporal sequence presentation data at a default presentation rate; (C) receiving request for the value of the presentation time parameter; and (D) returning the value of the presentation time parameter to a first component of the rendering system in response to the request; wherein the value of the presentation time parameter is not equal to the value of the data time parameter.
