Jae S. Lim received the S.B., S.M., E.E., and Sc.D. degrees in Electrical Engineering and Computer Science from the Massachusetts Institute of Technology in 1974, 1975, 1978, and 1978, respectively. He joined the M.I.T. faculty in 1978 as an Assistant Professor. He is currently a Professor in the Department of Electrical Engineering and Computer Science and is the Director of the Advanced Telecommunications Research Program.
His research interests include digital signal processing and its applications to image, video and speech processing. He has contributed a number of articles to journals and conference proceedings. He is a holder of more than 40 patents in the areas of advanced television systems and signal compression. His inventions have been used in numerous products including digital television receivers, cellular phones, satellite phones, and land mobile radios.
He is the author of a textbook, Two-Dimensional Signal and Image Processing. He is also the editor of a reprint book, Speech Enhancement, and a co-editor of a reference book, Advanced Topics in Signal Processing.
In the 1980’s, he participated in various activities of the IEEE ASSP (Acoustics, Speech, and Signal Processing) Society. He served as a technical program co-chairman of 1983 MDSP Workshop and 1986 ICASSP, and the chairman of 1984 DSP Workshop. He also served as the chairman of the DSP Technical Committee and secretary-treasurer of the Administrative Committee of the IEEE ASSP Society.
During the 1990’s, he participated in the Federal Communication Commission’s Advanced Television Standardization Process. He served as an ex-officio member of the FCC’s Advisory Committee on Advanced Television Service. He represented MIT in designing the MIT/GI System, which became one of the four finalist systems. He also represented MIT when the four finalist systems became a single system through the formation of the Grand Alliance. The Grand Alliance HDTV System became the basis for the U.S. Digital Television Standard adopted by the FCC in December, 1996. In 1997, MIT received a Prime Time Emmy Engineering Award for its contribution to the digital television standard. The television system with multiple video transmission formats, an important component of the digital television standard, was proposed by him.
He co-founded Digital Voice Systems, Inc. (DVSI) in 1988 and has served as the Chairman of the Board since then. He was a major contributor to the MBE (multiband excitation) voice compression technology developed at DVSI. The technology was adopted as the voice compression standard for many national and international communication systems and has been used in numerous telecommunications products.
Dr. Lim is the recipient of many awards including the Senior Award from the IEEE ASSP Society and the Harold E. Edgerton Faculty Achievement Award from MIT. He is a HO-AM Laureate in Engineering, a Fellow of the IEEE, a Member of the Academy of Digital Television Pioneers, and an Inductee of the Consumer Technology Hall of Fame.
