Kornelis Antonie "Kees" Schouhamer Immink (born 18 December 1946) is a Dutch engineer, inventor, and entrepreneur, who pioneered and advanced the era of digital audio, video, and data recording, including popular digital media such as compact disc (CD), DVD and Blu-ray disc.[1] He has been a prolific and influential engineer, who holds more than 1100 U.S. and international patents.[2] A large portion of the commonly used audio and video playback and recording devices use technologies based on his work.[3] His contributions to coding systems assisted the digital video and audio revolution, by enabling reliable data storage at information densities previously unattainable.[3]

Immink received several tributes that summarize the impact of his contributions to the digital audio and video revolution. Among the accolades received are the

Edison Medal[3] and an individual Technology Emmy award by the National Academy of Television Arts and Sciences (NATAS).[4][5] Beatrix, Queen of the Netherlands bestowed him a knighthood in 2000. He was elected a member of the National Academy of Engineering in 2007 for pioneering and advancing the era of digital audio, video, and data recording. Royal Holland Society of Arts and Sciences introduced the Kees Schouhamer Immink Prize in 2019 as a means to encourage research on information science and tele-communications.[6]

Currently, Immink holds the position of president of Turing Machines Inc, which was founded in 1998. During his career, Immink, in addition to his practical contributions, has contributed to

University of Duisburg and Essen, Germany, since 1994, as well as affiliated with the National University of Singapore (NUS) and Singapore University of Technology and Design
(SUTD) as a visiting professor.

Education

Immink obtained an Engineer's degree (Ir.) in electrical engineering (1974, cum laude) and a PhD degree (1985) from Eindhoven University of Technology on a thesis entitled Properties and Constructions of Binary Channel Codes .[11]

Early years at Philips Research

Fresh from engineering school, in 1967, he joined

CD
. The Laserdisc never managed a significant presence in market share. The Philips/MCA Laserdisc operation was not successful and discontinued in 1981.

Compact Disc

Around 1976, Philips and Sony[16] showed prototypes of digital audio disc players, which were based on optical videodisc technology. In the interview by Tekla Perry for the IEEE Spectrum, May 2017,[17] Immink explains that he got involved in the CD project at the end of 1979 when Sony and Philips had decided to jointly settle on one design. Both Philips and Sony had shown prototype CD players to the press in 1978. The team at Philips, he says, "needed someone to do measurements of the two competing systems, the quality, how they coped with scratches, how they coped with imperfections of the disc. My job with the LaserDisc was finished, so I said, 'Sure, I could do it.'" Both Philips and Sony had come up with different rules for translating digital audio data to sequences of pits and lands. After a lot of experimentation, Immink improved the playing time by thirty percent by inventing a code that could better cope with the servo systems. The encoding system Immink devised came to be called eight-to-fourteen modulation (EFM).

Immink took part in the joint

CIRC coding schemes.[18][19]

In the article, "Shannon, Beethoven, and the Compact Disc",

Beethoven's Ninth Symphony conducted by Wilhelm Furtwängler.[21] Commercial disputes also played a part.[20][22][23]

After the CD standard was set in 1980, Immink and his co-workers conducted pioneering experiments with

Laserdiscs
fabricated after 1984 have digitally encoded sound signals.

DVD and Blu-ray Disc

In 1993,

high-fidelity audio content. SACD is in a format war with DVD-Audio
, but neither has yet managed to replace audio CDs.

Immediately after the DVD standard was settled in 1996, Philips and Sony, disappointed after the DVD failure, decided to develop a next-generation blue-

high definition optical disc format war
.

DV and DCC

In 1985, Immink joined Philips's

magnetic recording group, where he contributed to the design of coding technologies of the digital video tape recorder, DV[35][36] and the Digital Compact Cassette (DCC).[37][38] The DCC was short-lived: introduced in 1992 and discontinued in 1996. The DV
, launched in 1994, has become a popular tape standard for home and semi-professional video production.

Turing Machines

After more than thirty years, Immink left Philips Research in 1998, and founded Turing Machines Inc., where he currently serves as its president. The small research institute has been successful in creating new coding technology and has been granted around ten US patents.[39]

Service to engineering society

Immink has served in officer and board positions for a number of technical societies, government and academic organizations, including the

Information Theory Societies. He was on the governors board of the Audio Engineering Society
for over 10 years, and was its president in 2002–2003.

Awards and honours

His papers have received several awards:

  • 2009 Chester Sall Award for ‘’DC-free Multimode Code Design Using Novel Selection Criteria for Optical Recording Systems,’’ IEEE Transactions on Consumer Electronics (Co-recipient with Jun Lee).[53]

KHMW Schouhamer Immink Prijs

The Royal Holland Society of Arts and Sciences established the Kees Schouhamer Immink Prize in 2019 as a means to encourage research on information science and telecommunications, two basic pillars of our information society. The prize, consisting of an honorarium and a diploma, is bestowed in recognition of a distinguished PhD thesis defended in the Netherlands.[6]
