methodology is needed to integrate and exchange spatial and temporal properties in hyper-media and hypertext. We propose a generic framework to structure and dynamically present a new form of video-and text-based media called hypervideo. We developed a Hypervideo Engine and produced an experimental hypermedia work, HyperCafe, to illustrate the general properties and aesthetic techniques possible in such a medium. W alter Cronkite once again presents the news, this time to a junior high school student watching a video clip on his computer. Cronkite says something about Vietnam, helicopters, and the ancient city of Hue. Another clip appears just to the right of the first one, and they play side by side for a few seconds.

The news clips would contain opportunities for action—called links in traditional hypertext—that appear at related moments.
