Broadcasting the CALI Conference for Law School Computing
  • We webcast some 30 sessions over 3 days from 5 different rooms. It all started out as talking head stuff, but folks were sad about the missing powerpoint slides:( So, last year CALI did a PinP trick that grabbed the PP, converted to NTSC, ran through a PinP box inserting room vid in the corner, and then on to vid capture and Real webcast. Hmm, good idea, but muddy slides and tiny pictures of big rooms wasn't too good.
  • My idea, with consultation from the guys at Duke, is to webcast the PP and the speaker audio, and video record the sessions to miniDV. Now, you would think it easy enough to grab a PP slide show, add audio, and blast it out over the net. You'd be wrong. It take a bit of work. But I got it solved in a way that will give us some cool stuff for the archives, a good webcast, bandwidth conservation, and digital video.
  • Here's how it works:
    • Configure Real's Helix server to broadcast windows media. This works well in a 'pull' mode from the windows media encoder. A benefit is that the server will not begin the pull until a client requests the stream. So, if nobody tunes in, no unused bandwidth.
    • Run WM Encoder on each of the room PCs and set it to screen capture mode with audio only and archiving. This will save a .wmv file of audio with the slide show as the video component. Set WME to listen on port 8080 for a request from a media server, so if anyone wants to watch/listen they can.
