It's not really DIY at 50Mbps.<br><br>=P<br><br><div class="gmail_quote">On Fri, May 21, 2010 at 5:17 PM, Sylva1n <span dir="ltr"><<a href="mailto:sylv41n@gmail.com">sylv41n@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
Streaming talks is nice, but allows not much interactivity, except<br>
asking question through IRC during Q&A sessions ... not much better<br>
than watching said talks on youtube days or moths later.<br>
<br>
OTOH, with a good net connexion (>50Mb) and some beefy hardware,<br>
shouldn't it be possible to setup at least 3 or 4 small to medium size<br>
rooms, with bidirectional HD video (720p-ish), where transatlantic<br>
workshops and/or panel discussions could take place ?<br>
Such DIY-telepresence could be a great demonstration of what ingenuity<br>
can do to reduce drastically the number of unnecessary transatlantic<br>
flights.<br>
<br>
Wikipedia indicates a 14 Mbps bitrate for h264/base<br>
profile/1280×720@30fps, has any of you experience with streaming as<br>
such bitrate ?<br>
Can a modern 6-to-8 core machine do real-time transcoding from a<br>
webcam (eg. Logitech PRO 9000, 960x720@13fps) through x264 at such<br>
rate ?<br>
How hard is it to set-up a 50 Mbps reliable transatlantic IP link ?<br>
Can a neighborly-friendly ISP carry such load, or do you have to make<br>
special arrangements with a transit provider or ask an academic<br>
network ?<br>
