Title: Timestamp modification for seamless branching

Abstract: The modification of timestamps of streams of data packets for seamless branching is disclosed. In one aspect of the invention, a computerized system has a plurality of multimedia play devices, and a multimedia read device. Each play device receives and plays data intended for that device. The multimedia read device reads a stream of packets of data, decodes the packets into data, and sends the data to a corresponding play device at appropriate times. The appropriate time is based on relative timestamps accounting for accumulated time gaps resulting from branches within the stream. The invention has applications including digital video disc (DVD) playback.
