Could I impose upon you to explain -a little- as to why there are three
H.32X standards when, from what you dscribe as to what they apply to,
only the connection differs from one standard to next. In otherwords,
I guess I would have expected the underlying transport machinery to
pretty much not matter alot to the higher level layers of video conferencing,
unless it wasn't a layered architecture in the first place.

just askin',

H.320 is for video conferencing on ISDN lines, H.324 is for video
conferencing on analog lines, H.323 is for LAN based video conferencing
(in the Internet and in intranets)
