Short description: Unable to attend 31C3? Watch the 31C3 streams from our hackerspace

synopsis

Watch 31C3 live on a projector in the space, or listen to it via the phone. Phone extensions are yet to be determined (most likeley 1301 to 1306)

Xopr wrote an XBMC remote control script for streams to switch channels from within a console with just one keypress.

Also see CCC's Congress_everywhere

intro

  • Xopr is trying to put up multicast on 239.255.255.42, so we don't unnecessarily overload our (and CCC's) external bandwidth.
  • Streams will be on:
    • Saal 1 (native), rtp://@239.255.255.42:9001
    • Saal 2 (native), rtp://@239.255.255.42:9002
    • Saal G (native), rtp://@239.255.255.42:9003
    • Saal 6 (native), rtp://@239.255.255.42:9004
    • mosaic, rtp://@239.255.255.42 (default port 5004)
  • Note that we don't have descent accesspoints (and no QOS), so it will be choppy on wifi: use a cable
  • There are 4 streams, we have 2 rooms, 1 projector (beamer), 3 TV's (and plenty monitors) and 2 hi-fi stereos in our hackerspace.
  • The lectures take place from (about) 11:30 until 02:00, and the hackerspace closes after the last person leaves.
  • Decide per lecture which lecture we are going to watch and show it on the projector with audio via the hi-fi stereo.
  • Either watch the other streams on the two tv's but with muted audio and/or they can be watched from your laptop with headphones
  • Alternatively, you can either log on into our phone system internally, or tap in externally, and dial 1301, 1302 and 1303 for the three rooms respectively. Note that phone audio will certainly not be in sync with the video streams.
  • Workaround: watch the other streams from your laptop with headphones, or use the phone (1301-1303) to add audio as a poor man's solution.
