Procurement costs for a high-end digital system for each side can vary widely depending on the sophistication of the system. Hourly operation can also be expensive. Toward the top end, a T1 line system can run thousands of dollars an hour if bridged to multiple sites. Examples of high-end digital systems are many. The system connects a classroom at ERAU s Daytona Beach, Florida campus with their Prescott, Arizona campus.
Some classes originate in Arizona while others originate in Florida.
The system provides high quality video and good audio between the two sites. To compensate, most of these systems use a small video window rather than displaying the video image on the full screen. The also often allow computer applications to be shared by all participates simultaneously which is good for classroom demonstration of software. These work very much like the low-end digital line systems but are even more constrained in the bandwidth available for carrying the video image. Consequently, the clarity and speed of the image is even more compromised.
