Abstract: A new proposal is made for a preferred progressive-scan alternative to interlace as the standard for high-definition electronic production. Combining quincunx subsampling with digital-assist interpolation, the proposed QDA system can be recorded or transmitted in the same bandwidth as that of an interlaced standard of the same number of total lines and field frequency. Thus QDA achieves essentially the same static resolution but twice the dynamic resolution of interlace, making it a preferred choice for production and post-production. Simulations of the system, comparing its performance with that of interlace and of diagonally filtered quincunx methods, are described.

bio
Dr. Kerns H. Powers retired from RCA in 1987, after 35 year of service, with a speciality of communications engineering, especially television. He is currently a consultant for NBC, the David Sarnoff Research Center, and other clients. After graduation from the University of Texas in 1951, Dr. Powers joined RCA Laboratories at Princeton, New Jersey, to work on dot sequential television, the forerunner of NTSC. Over the years at RCA, his work involved high-resolution radar, ELF transmission, data communication, satellite communication, video, and enhanced definition television. He became a group head in 1959. Director of the Communications Research Laboratory in 1966, and Staff Vice-President, Communications Research in 1977. At the time of his retirement, he was in charge of research in support of the communications, broadcasting, and government systems businesses of RCA. Dr. Powers received B.S.E.E. and M.S.E.E. degree from the University of Texas in 1951, and an Sc.D. from Massachusetts Institute of Techology in 1956. He has 16 issued patents and has published numerous technical papers. His honors include the Forty-One for Freedom from the U.S. Navy in 1967, delivery of the prestigeous Shoenberg Lecture before the Royal Television Society in 1987, and the Progress Medal of SMPTE in 1988. He is a Fellow of the IEEE and of SMPTE.
