Still pictures with audio 28Kbps slideshow 28Kbps slides, music, and text These examples demonstrate the quality available at different bandwidths for different uses of streaming. Audio requires the least bandwidth, and therefore has the best quality at modem speeds.
Video suffers from a low frame rate and poor picture quality.
Slideshows offer a compromise of good quality still images synchronized with audio. Better quality is possible with higher bandwidths, but maintaining that bandwidth for an extended period is a problem. As network congestion occurs, the playback quality can degrade to the point where the video freezes and the audio breaks up. The more bandwidth required by a file, the more likely network congestion will occur. At Cornell, many students connect by modem through the modem pool.
