Matching Interactive TV and Hypervideo

The paper reports an approach to develop an interactive TV system based on the concept of hypervideo. The great innovation the concept of hypervideo proposed in this paper brings is the possibility to associate different complementary information about the objects shown in scene. The association between those complementary information and video is made by embedding hyperlinks (references) into a digital video being transmitted, allowing the user to access such information by clicking in an area of the image being watched. This is an innovative approach for interactive television in the sense that it admits the association of video and context sensitive information. A concept proof prototype, developed to illustrate the ideas proposed, is presented in this paper.
