Abstract: In this paper, we describe some methods for adding additional information to a compatible NTSC broadcast signal so that an advanced receiver can decode that information to provide improved picture quality (Extended Definition Television, EDTV), while a standard NTSC receiver will display an image with minimally visible impairments. 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.

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.

Dr. Arun N. Netravali is director of the Computing Systems Research Laboratory at AT&T Bell Laboratories, with reponsibility for research in artificial intelligence, VLSI design aids and architectures, communication networks, distributed computing, programming languages, software engineering, and interactive systems. He joined Bell Laboratories in 1972 as a member of the technical staff, became head of the Visual Communications Research Department in 1978, and assumed his current position in 1983. He was at NASA from 1970 to 1972, where he worked on problems related to filtering, guidance, and control for the space shuttle. He has been an adjunct professor at the Massachusetts Institute of Technology since 1984, and has taught graduate courses at City College, Columbia University, and Rutgers University. Dr. Natravali received the B. Tech (Honors) degree from the Indian Institute of Technology, Bombay, India, in 1967 and M.S. and Ph.D. degrees from Rice University, Houston, Texas, in 1969 and 1970, respectively, all in electrical engineering. He received the Donald G. Fink Award for the best review paper published in the Proceedings of the IEEE in 1980, the journal award for the best paper from the Society of Motion Picture and Television Engineers in 1982, and the L. G. Abraham Award for the best paper by the IEEE Communications Society in 1985. He is an avid tennis player and has won several local championships.

William F. Schreiber attended New York City public schools and Columbia University, where he received a B.S. and M.S. in electrical engineering. In 1953, he received a Ph.D. in applied physics at Harvard University, where he was a Gordon McKay and Charles Coffin Fellow. Dr. Schreiber worked at Sylvania from 1947 to 1949 and at Technicolor Corp. in Hollywood, Calif from 1953 to 1959. Since then he has been a faculty member at MIT, where he is now professor of electrical engineering and director of the advanced television research program. He was visiting professor of electrical engineering at the Indian Institute of Technology, Kanpur, India, in 1964–66, and at INRS-Telecommunications, Montreal, Quebec, 1981–82. Since 1948, Dr. Schreiber's major professional interest has been image processing. He has worked in graphic arts, including color processing and laser scanner design, in facsimile, and in television. This work has included theory and extensive practical applications. He is a Fellow of the IEEE, an Honors Award recipient of the Technical Association of Graphics Arts, and has twice received the best paper award of the SMPTE Journal.
