Abstract
Two sequences of signal packets are played. Each signal packet of a first type of signals has been stamped with a sequence number corresponding to the position of the signal packet in the first sequence. Each signal packet of a second type of signals has been stamped with a corresponding sequence number of the first sequence. The playing of the second sequence is synchronized with the playing of the first sequence by comparing the sequence numbers of the second sequence to the sequence numbers of the first sequence. In a preferred embodiment, the two types of signals are audio signals and video signals, and the video signal packets are stamped with sequence numbers for the audio signal packets. Each video signal packet of the video sequence is processed for display based on a comparison of the sequence number for the video signal packet and the sequence number for the current audio signal packet.
