Networked Hyper QuickTime (NHQT) is a prototype education-on-demand system for delivering hypermedia annotated video over the Internet. NHQT uses World Wide Web, Gopher, and QuickTime technologies to deliver video streams with embedded uniform resource locators that point to ancillary documents or video streams. NHQT's video-based user interface supports VCR-style playback control, random positioning, content-based searching, and automatic resolution of hypermedia links for Internet access.

Funding Information:
We believe the Internet’s infrastructure will gradually migrate and incorporate high-speed networks to handle large numbers of users and applications requiring a high-aggregate bandwidth. Under a National Science Foundation (NSF) research grant, we’re developing an extensive ATM campus-wide network including high-end workstations and PCs. A small-scale ATM testbed within the campus-wide ATM network has a Fore System ASX-200BXE ATM switch connecting to a heterogeneous workstation environment with one Power Macintosh 8100/100AV, one Power Macintosh 7100/66, one Sun SparcStation 10, and one Silicon Graphics high-end Challenge machine. We built this ATM testbed network using a Macintosh as the user workstation to assimilate sender-receiver interaction within the high-speed network infrastructure. It will help us explore how NHQT could work over future high-bandwidth networks,
