Explains videodisc technology and its uses in education. Topics addressed include formats of videodiscs, including CAV discs (constant angular velocity) and CLV discs (constant linear velocity); the three industry-standard levels of interactivity; bar codes; bar-code readers; and finding information on a videodisc.

A multimedia encyclopedia (MME) demonstration disk has been developed by the Microsoft Corporation, which contains five-page articles on 12 subjects. Each article contains text, images, audio, and in some cases, animation and full motion digital images. Each MME article is constructed as a network of linked text, image, and sound files. With mouse…

This discussion of the laser videodisk begins by noting that it is an extremely high density visual storage medium that can supply instructors with vast visual warehouses to supplement instruction, whether through conventional group presentations or via individualized computer assisted instruction. Major features of the medium are then described…

Interactive video can be a very complex learning system, or it can be a simple tool for teachers to use to enhance their instruction. The term has been used broadly in the literature and includes three major aspects: (1) interactive video as storage; (2) interactive video as hardware; and (3) interactive video as learning concept. This digest…

This digest begins with a brief description and review of the development of optical disks. Optical disk formats are then described by capability: Read Only Memory (ROM), Write Once, Read Many (WORM), Interactive (I), and Erasable (E); forms of information (audio, text or data, video or graphics, or a combination); and disk size (most often 12 or…

Arguing that videodisc technology has major implications for the storage and retrieval of information and that it may meet learners' needs in ways never before possible, this paper highlights key points regarding the history and development of videodisc technology, explores its implications for education, and addresses current and future uses of…

Discusses the need for a rich semantics for the user interface in interactive image retrieval and presents two methods for building such interfaces: possibility theory applied to fuzzy data retrieval, and a machine learning technique applied to learning the user's deep need. Prototypes developed using videodisks and knowledge-based software are…

Describes a microcomputer-based multimedia system that enables videotape presentations to be created by assembling still or moving data, with sound and in color, from a variety of sources. Source media include Macintosh storage of text and graphics, and various types of videotape and disc players. (18 references) (CLB)
