I tackled the general point in my talk, and this thread extends what
I was on about *very* nicely.
In the best of all possible worlds ...
- George sends multiple feeds out into the world
- some of the feeds have some form of synchronisation mechanism
(whereas others, such as commentaries, don't need it)
- people subscribe to the feeds they want
e.g. by ticking boxes on a control-page
(the page needs to indicate the bandwidth needed to support each feed)
- the feeds arrive in windows that can be sized and moved
- people can sculpt their access according to personal preferences,
device characteristics, bandwidth availability, etc.
- a couple of bundled options can be offered, which have fairly fixed
display arrangements (e.g. low-res talking-head top-left, slides
bottom-left, commentary-feed top-right, control-panel bottom-right)
- the bundled options can be provided by the multi-caster or any
intermediary (which could also offer its own parallel feed)
Yes, it assumes a *lot* at the multi-casting end. But Pia, George
and Bob Edwards [did I miss someone??] showed that a lot can be
strung together in quick time. (I grinned at George when I asked him
what his fallback arrangements were; and he grinned back).
Yes, it assumes a fairly high level of user sophistication, which in
the short term means an amount of disenfranchisement.
Yes, I'm aware of the existence of protocols that enable some of this
(but I'd have to go and read my notes to get myself back into the
alphabet soup, and then update myself on progress since I last
Yes, I'm sure AARNet was supporting things like this some years ago;
but did they down-scale and productise the results of their work?
No, I'm not aware of anything ready to roll that does all this; but
then I only bring my scepticism to bear on these kinds of services
every few years (:-)}
Yes, I'd be *much* more enthusiastic about such a multi-streamed and
de-coupled video-conferencing architecture than I am about the mere
'talking head' stuff that has dominated practice for the first 35
