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 IVS (INRIA's 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)?
