Cornell Information Technologies is running a RealNetworks server, so if you use our server, you will need to use players and tools compatible with this technology. Use it to make audio and visual materials available to your students. These tapes can be made available with good audio quality. To a degree, these can be made available although at much lower quality, and much smaller frame size. You can also create slideshows that are synchronized to an audio track.
Quality is dependent on the bandwidth, or the amount of data that needs to be moved per second.
We recommend using modem speeds of 28Kbps to 56Kbps, since this is the lowest common denominator that your students will be able to use. At these speeds, audio is comparable to a radio broadcast, but video will play in a small window, have poor motion, and be blurry. The easiest way to judge this is to look at some examples . While it's attractive to consider using video, ask yourself if it's really necessary. Students connecting to the Internet through Cornell's modem pool will have trouble maintaining even the low video data rates for extended times due to the extremely heavy use the modem pool receives.
