This system is designed to be used immediately for controlled-access systems such as cable. It is also suitable for eventual broadcasting use in a two-stage strategy in which an intermediate backward-compatible system is the first stage. Applications to fm, recording, and digital transmission are described. The efficiency of analog channel utilization is improved over NTSC by using double sideband quadrature modulation of two 3-MHz signals on a single carrier in the center of the band, and by elimination of the retrace intervals and sound carrier. Higher perceived quality for a given transmission rate is achieved by dividing the signal into components according to both spatial and temporal frequency, and transmitting the appropriate combination of components according to the degree of motion in each scene. A “smart,” programmable, open-architecture receiver is proposed capable of decoding a wide variety of signal formats and displaying the image at higher line and frame rates than transmitted. Such a receiver can also display the backward-compatible EDTV system described in a companion paper, and can be upgraded over time by virtue of its programmability and by adding hardware and software modules.", "abstract$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/Source Bak/smptem/10.5594_M00532.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": "William F. Schreiber attended New York City public schools and Columbia University, where he received a B.S. and M.S. in electrical engineering.

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.
