StudyQuestions - NC - FieldTrip

The Videoconferencing Field Trip should be well understood if the following questions can be answered:

• How does the amount of network bandwidth consumed differ when one deals with CU-SeeMe, ShowMe, and software for the MBONE?
  
• How does video and audio quality differ for these three systems?
  
• How does selection of algorithms for compression relate to video and audio quality achieved with these three systems?
  
• Which system seems to be most computationally expensive? Why?
  
• If student-faculty communication were to take place using ShowMe, what would be the role and value of its support for a shared whiteboard?
  
• How could the MBONE reduce network traffic if four sites were to engage in an interactive conference, sending and receiving with each of the other three?
  
• What are a few advantages of having a dedicated network connection (e.g., ISDN connection) for videoconferencing instead of sharing a packet switched network (e.g., Internet)?
