Could you be any more blunt about this?
Indeed I could.
As a rule, I reply with a similar tone to the one I received. And that is
why I responded in the way I did.

Yes it is.
The mpeg lip sync is only for the video and audio being

I thought that only worked when transmitted over a serial link, i.e. ATM
or DVB.
You thought wrong.
It is not so effective on packet based links such as Ethernet.
All headend distribution systems these days are Ethernet-based. It is
incredibly effective.
I have never heard of those

Hi,
Does anyone have experience of both ntp and ptp ?
Which is likely to be better (keep them synced to the best accuracy
and lowest variance) at syncing three PCs on a LAN without a switch
that supports ptp?
My understanding is that in order for ptp to be better than ntp, the
network switch has

Hi again,
Did a little bit of reading and a simple test..
For software only PTP, you are probably better off with NTP. For hardware
assisted PTP, only the NIC's have to support timestamping. Most Intel gigabit
controllers do (IGP driver).
I did run a couple of little tests in a pure virtual
you are probably better off with NTP.
it pretty much depends on the requirements.
If you need the precision of ptp, nothing else will do. This particularly
applies when you have asymmetric network lag and need really accurate
time.
For everything else, ntp is trivial to set up, and works just
