HDTV Digital Frame Recorder
Marc Klingelhofer, Vinson R. Perry · SMPTE Journal · 1991
This article describes the newly developed high-definition digital frame recorder, the Sony HDDF-500. It was developed as a versatile new tool, based on the SMPTE 240M 1125-line, 60-Hz standard for HDTV. The three-channel (G, B, R), equal-bandwidth recording system uses dynamic RAM memory to capture images from a real-time analog or digital source. It operates like an HD digital VTR, with the potential application for special effects and animation in the motion-picture industry, for computer graphics and image storage in the printing and publishing industries, and for many other industrial applications requiring storage and retrieval of HDTV images.
