<p>A method for accessing a desired point in time-synchronized data within a stream, the stream being associated with time information, comprises, providing a desired presentation time associated with a desired point within a time-synchronized data stream, determining a stream access point, decoding the stream beginning at the stream access point and continuing to decode the stream until a time at which presentation time information associated with the stream corresponds to a presentation time greater than or equal to the desired presentation time, and assigning a time associated with the stream access point as a utilization time. The time associated with the stream access point comprises the time at which presentation time information associated with the stream corresponds to a presentation time greater than or equal to the desired presentation time.
