Dear Q.11-15 experts,

Attached find please the rev.3 of H.245 codepoints for MPEG-4 visual

The change from rev.2 is only on the default value of the drawingOrder
as in the Q.11 meeting report.

In the determination version (and in rev.2), the default value of the
drawingOrder was 0. It is equal to the minimum value of the
drawingOrder. It makes a limitation that a logical channel cannot has
the smaller drawingOrder value than that of the logical channel formally
opened without indicating drawingOrder. This means that a visual object
cannot drawn Behind the visual object associated with the formally
opened logical channel with default drawingOrder.

I changed the default value to 32768, which is the middle of maximum and
minimum values.

Please note that the format of rev.3 is quit changed form rev.2 as the
delta from H.245 ver.4, but the contents should be the same expect for
the above change.

If you have any comment on it, please send a message until the end of
this week. I will make changes with reflecting all comments, and will
send it to the H.245 editor (Mr. Mike Nilsson) next week.

Best regards,
