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 various videoconferencing systems?
  
• How does video and audio quality differ for these systems?
  
• How does selection of algorithms for compression relate to video and audio quality achieved with these systems?
  
• Which system seems to be most computationally expensive? Why?
  
• If student-faculty communication were to take place using videoconferencing, what would be the role and value of its support with a shared whiteboard?
  
• How could the multicasting like MBONE reduce network traffic if four sites were to engage in an interactive conference, each 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)?
