  • Basic two site setup. CXP manages audio and video connections through venue. Sites will contribute multiple video streams. All information from venue is also put into the Archiver.
    CP3 runs on the instructor tablet withs student tablets connecting directly to the instructor. The instructor connects to displays at both sites. CP3 connects to the venue so that the content can also be stored in the archiver.
  • The 3 way setup between UW, Microsoft, and LUMS. The reason that two venues are used is that higher bandwidth is available between UW and MS – so high bandwidth video goes into venue 1, and lower bandwidth (256kbps) goes into venue 2
