Dear Mr. Baese, experts,
After much discussion here on the reflector, I thought Mr. Baese had agreed
on the following two points:
(1) The simulation will be performed using H.263 Profile 3 and Profile 4.
(2) For the benchmark case (without proposed protection) that both of the
proposal are compared to, the Annex K/V in Profile 3/4 of H.263 will be used
so that the packets fits in the MTU of the channel.
However, neither of these are incorporated in APC-1993r2 Mr. Baese just
resent. Those conditions are in the document I sent earlier (which combines
APC-1906 and APC-1993), and I haven't heard from Mr. Baese any technical
objection on the detail of that document. So our document may be a better
base for the combined testing condition document.
On the second document for feature comparison, at this time, both sides
should submit *individual* documents detail the views with technical
analysis. From the way that the discussion on the testing condition goes,
realistically there is little chance that an agreed feature comparison
document can be completed within 3 days to meet the deadline. So submitting
two individual documents would be a practical solution at this time.
On the finger pointing in discussion, I have no interest to participate.
Have a good day.
