Mark Pearrow of CSAIL TIG has set up Kiva with essentially always-on media streams of a '''webcam in the back of the room''' and the video of anything connected to '''vga port 1'''. Additionally, audio is captured from a lapel mike stored in the cabinet at the back of the room (on which the webcam is perched).  Mark recommends using VLC to connect to the two streams:

Video of today's SynBERC lunch should be available in real time (minus ~20 seconds) via the internet tubes in two different formats: the VLC videostream described previously, and as a quicktime streamThis quicktime stream is a test of the setup that will be used to broadcast [[SynBERC:Seminar_series/Steve_Benner|Steve Benner's talk]] tomorrow, so if it works for you today, it should work tomorrow as well.

VLC on Mac OS X cannot open two media streams simultaneously, so Mark suggests making a duplicate copy of the VLC application with a name like 'VLC 2' and using it to connect to the second stream.

Anyone in the synthetic biology community is welcome to attend.

32-G449, MIT

Topic of discussion

Natalie Kuldell will lead a discussion on education in synthetic biology including the following topics...

  • What curriculum exists (and an open discussion of their efficacy)
  • What communities would benefit/find usefulness in the materials
  • What content should be taught (a big topic)
  • How to best convey material (comic 2.0 vs web tutorials vs SB majors vs textbook etc.)
  • What's holding us back (maybe...this might be part of all the rest of the topics and doesn't need a separate header).

Remote participation

  • Reshma 16:44, 13 March 2007 (EDT): On 3/13/2007 we managed to have video but no audio. We're working on getting mikes placed around the room so that you can hear the discussion.

  • Wmholtz I was able to connect to all three streams on 3/20/2007. I was a bit surprised that I was having CPU limitation issues (P4 2.8GHz).

Video

An archive of the video stream is available on blip.tv.

Video of today's SynBERC lunch should be available in real time (minus ~20 seconds) via the internet tubes in two different formats: the VLC videostream described previously, and as a quicktime stream. This quicktime stream is a test of the setup that will be used to broadcast Steve Benner's talk tomorrow, so if it works for you today, it should work tomorrow as well.

Streams

rtsp://caprica.csail.mit.edu/SynBERC.sdp - the Quicktime stream, camera position uncertain
http://xibalba.csail.mit.edu:8080 - Camera looking from back of room towards presenter
http://xibalba.csail.mit.edu:8081 - slides from laptop input 1 (if anything is connected)

Connection Instructions

Quicktime stream: In quicktime go to menu >> Open URL and paste the address into to menu dialog.

VLC streams: in VLC go to menu >> Open Network and paste the address into the menu dialog, taking care to clear it of any defaults first.


Note that VLC can actually open all three streams; quicktime player is not essential.

Also note that the OS X version of VLC does not provide options for opening more than one stream at a time; a quick and dirty workaround is to duplicate or triplicate the VLC application and open a different stream in each copy.
