Removing jitter by adaptive slope tracking
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.
