In particular, we transmit chrominance information at one half the frame rate and use alternate frames to encode high definition luminance information in the chrominance signal. This is useful for any EDTV system. We also suggest a particular design where we usurp some active lines from the top and bottom of the picture and encode augmentation information into this region so that both the EDTV and the NTSC receiver receive similar looking wide screen pictures, the EDTV one containing greater resolution.", "abstract$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/Source Bak/smptem/10.5594_M00531.xml)", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" }, "authors": [ { "affiliation": "Massachusetts Institute of Technology Cambridge, Massachusetts", "bio": "Andy Lippman is associate director of MIT's Media Laboratory. He is currently director of the electronic publishing group within the lab and is principal investigator of a new reseach program addressing the “future of the movies.” This program focuses on the intelligent interaction between computing and sequential visual images. A highlight of it is “paperback movies,” work to compress a movie into a digital representation suitable for distribution on a compact disc. In the past, he directed the architecture machine group and led the development of such interactive systems as the Movie-Map, a videodisc-based map of Aspen, Colorado, and the Movie Manual, an electronic book. In addition, he directed research programs on teleconferencing, news information systems, display technology, and high-definition television.", "name": "A. B.
