Reviews the state of information technologies involving teletext, viewdata, interactive graphics, videodisc, audio synthesis, and holography, and discusses the current understanding of access schemes and cognitive processing. Sixteen suggested readings and nine references are cited. (FM)

Details distinction between digital and analog data, advantages of analog storage, and optical disc use to store analog data. Configuration and potential of three levels of laser disc systems are explained. Selection of display devices for use with laser disc systems and accessing audio data are addressed. (Continued in next issue.) (EJS)

Describes new technology known as videodisc, including optical videodisc, capacitance electronic disc, and video high density disc. Entertainment, educational, training, and information storage and retrieval potentials of videodiscs are discussed. A list of agencies active in optical disc applications, useful Canadian videodisc contacts, and a…

Reviews projects that have examined different aspects of videodisc--potential for multimedia storage, capability to provide interactive instruction, characteristics as electronic media bridging old and new information technologies--and discusses theoretical and practical issues associated with current and future use of videodisc for instruction.…

Availability of low-cost digital optical disks will revolutionize storage and retrieval systems over next decade. Three major factors will effect this change: availability of disks and controllers at low-cost and in plentiful supply; availability of low-cost and better output means for system users; and more flexible, less expensive communication…

Reviews attributes of laser discs and "traditional" objections to use of audiovisual materials. Use of authoring systems as means of tailoring laser disc programs and updating aging materials is described. Flexibility and power of the Video Nova Authoring System is explained and illustrated and the SONY SMC-70 microcomputer is evaluated.…

This paper describes the development of textual information displays for home consumption on modified television receivers in Great Britain over the last few years, compares two systems in use there--Teletext and Viewdata--and discusses some future possibilities for such services in the U.S. as well as the U.K. British television equipment…

Reviews recent technological advances and developments relating to input devices, storage devices, output/display devices, and multimedia systems. Actual and possible applications of these technologies in the library, publishing, and information environments are discussed. (24 references) (CLB)

Uses the different search environments of information brokers and institutional searchers to illustrate the factors that should be considered when selecting microcomputers for search operations. The factors discussed include speed, storage capabilities, displays, modems, printing technologies, facsimile transmission, and portability. A directory…

This paper describes some of the advances in telecommunications technology that can be anticipated during the 1980's in the areas of computer and component technologies, computer influences on telecommunications systems and services, communications terminals, transmission and switching systems, and local distribution. Specific topics covered…

This discussion of the use of images in learning processes focuses on recent developments in optical storage disc technology, particularly compact disc read-only (CD-ROM) and optical video discs. Interactive video systems and user interfaces are described, and applications in education and industry in the United Kingdom are reviewed. (Author/LRW)
