1 There are many different video and audio encoding formats
  • Wide variation and tradeoff between quality, bandwidth needs and CPU demands for encoding and decoding
  • Popular ones (Real Audio, Real Video) are not designed for audio video conferencing but rather asynchronous streaming
2 Image quality requires that one take "foils" from computer and not video shots. This is impossible unless lecture delineated into "nuggets" and beginning and end of each nugget time stamped
3 Need very good time synchronization between video and computer and between different participants in distance delivery
4 Quality of recorded lectures is often poor and suggests need for editing
5 Should one associate audio/video with a "nugget" or a lecture?
