Description

From the Wikipedia:

"Hypervideo, or hyperlinked video, is a displayed video stream that contains embedded, user clickable anchors,[1] allowing navigation between video and other hypermedia elements. Hypervideo is thus analogous to hypertext, which allows a reader to click on a word in one document and retrieve information from another document, or from another place in the same document. That is, hypervideo combines video with a non linear information structure, allowing a user to make choices based on the content of the video and the user's interests.

A crucial difference between hypervideo and hypertext is the element of time. Text is normally static, while a video is necessarily dynamic; the content of the video changes with time. Consequently, hypervideo has different technical, aesthetic, and rhetorical requirements than a static hypertext page. For example, hypervideo might involve the creation of a link from an object in a video that is visible for only a certain duration. It is therefore necessary to segment the video appropriately and add the metadata required to link from frames - or even objects - in a video to the pertinent information in other media forms."
