22c3: video and audio streaming and recording scheme


As promised yesterday here are some more information about the video and audio streaming and recording at the 22c3. First let’s start with the almost complete scheme:



What’s not in the scheme is where and how the streams are recorded:




  1. there’s a DV tape in every camera (we’ve got 400 brand new DV tapes for that purpose here)


  2. audio+video streams are recorded on the CCC encoding machines on their local hard drives (MPEG2 audio and MPEG4 video)


  3. audio+video streams are record on the FeM encoding machines on their local hard drives (Windows Media Audio+Video 9)


  4. audio-only streams are recorded on the CCC streaming servers local hard drives

Last but not least: How can you watch and hear those fantastic streams? Easy:


Two ways:

inside the Phone Operation Center (POC)


Since we are kind of interested in providing a large user DECT network on the campus of our university we spoke with the Eventphone guys about their setup: and as far as we can tell it’s far more sophisticated than expected.

Well sorry that there are more pictures than text – it’s just because we have to compile all the information we got and pile it all together into a nice and well understandable text for your reading pleasure.
