Digital video is becoming a viable alternative to the analog videodisc for multimedia in Computer Based Training (CBT) and other applications. The benefits of digital video are lower cost delivery platform hardware and more efficient processes for production, distribution, and maintenance. Today, there is a wide variety of hardware and software products available to implement digital video for multimedia including PLV, DVI, RTV, Motion JPEG, MPEG, Indeo, Quicktime, Cinepak, Ultimotion, and others. There is a wide variation in the quality and cost of these alternative solutions. Consequently, multimedia content developers are faced with a confusing array of options when it comes to using digital video. The objective of this paper is to compare the available methods of providing digital video to facilitate selection of the best approach for a given application. The paper includes a tabulation of performance, quality, and cost parameters to enable making informed choices. The different techniques of compression / decompression are briefly described together with the hardware and / or software needed to implement them. Decompression by software is particularly attractive since it does not increase the cost of the delivery platform. Hardware to play back the compressed video is also becoming more affordable and is the preferred solution when full motion, full screen video is required. Networking of digital video is briefly covered. The impact of emerging standards on the development of future products is discussed.
