Abstract
The present invention addresses the issue of jitter compounded by clock drifting in streaming media applications. In addressing jitter, the present invention attempts to recover the desired (de-jittered) arrival time at a gateway even if there is a frequency difference between the clocks of the original media source and the gateway. The desired arrival time is used with the addition of a constant to schedule the packet delivery time for delivery to a user via a network. Each packet arriving at the gateway contains an arrival timestamp. Using packets, which also contain sending time stamps, the invention determines the delivery time for each packet.
