Abstract
A computing system that has access to a streamed multimedia sample that is stored on a storage medium applies a zero-based presentation timestamp numbering scheme to the data packets of the multimedia sample, on-the-fly, and after each seek operation. After seeking to a desired starting point, the computing system reads ahead a maximum number of data packets within each media stream of the multimedia sample. A smallest timestamp (normalizing presentation timestamp) is identified and then subtracted from the timestamps of the data packets that are transmitted to the appropriate rendering devices, thereby creating appropriate presentation timestamps for the data packets for synchronizing the playback of the multimedia sample.
