Video-Based Hypermedia for Education-on-Demand
January-March 1998 (vol. 5 no. 1)
pp. 72-83

Networked Hyper QuickTime (NHQT) is a prototype education-on-demand (EOD) system designed to deliver hypermedia annotated video over the Internet for low-cost desktop PC systems. It also provides easy-to-use editing functions to embed annotations and hypermedia links into a video. These handy operations make authoring viable in terms of time and simplicity for busy instructors without any experience in video editing. NHQT uses WWW, Gopher, and QuickTime technologies to deliver video streams with embedded Uniform Resource Locators (URLs) pointing to ancillary documents or video streams. Incorporating URLs in a video presentation lets users follow hypermedia links to documents and video segments that are pertinent to the section of the video being viewed.

NHQT?s video-based user interface supports a full range of user interaction, including VCR-style playback control, random positioning, content-based search, and automatic resolution of hypermedia links for Internet access. A testbed of ATM network for Macintosh and workstation platforms has been built to study the future high-speed network infrastructure with NHQT.
