SMPTE Tutorial: The Computer-Controlled Frame Buffer as a Production Tool

Abstract

This article describes the many uses of the digital frame buffer under computer control, as in digital video effects systems (DVE). An even greater variety of effects is possible when the buffer is combined with a general-purpose computer and directed by user software. The article examines the influence of the buffer structure on television production operations, and describes how a particular system is being used both to produce television images for commercial use, and to develop new techniques for future applications.
