Re: FW: Delta and skew value in RTP analysis

[Martin Visser <martinvisser99 () gmail com>]

If you crunch the maths on the timestamps, I am sure you could have worked
it out.

Delta is simply the difference between the current packet and the previous
packet in the stream.

Skew is a measure of how late (or early) the current packet is for the total
conversation (relative to the nominal packet rate). So if the packet rate
should be 50 pps and say the 1000th packet of the conversation arrives 20.03
seconds after the 1st then the skew for that packet would be -30ms
