Sloot Digital Coding System

Jan Sloot, Sloot Digital Coding System

This Technology is not exist in the world. Because he murdered before sell own CODE in Company.

Romke Jan Bernhard Sloot (27 August 1945, Groningen – 11 July 1999[1]Nieuwegein) was a Dutch electronics engineer[2], who in 1995 claimed to have developed a revolutionary data compression technique, the Sloot Digital Coding System, which could compress a complete movie down to 8 kilobytes of data — this is orders of magnitude greater compression than the best currently available technology in the 2010s. He died suddenly on July 11, 1999 of a heart attack, just days before the conclusion of a contract to sell the invention. The full source code was never recovered, and the technique and claim has since never been reproduced or verified.

Early life

Sloot was born the youngest of three children. His father, a school headmaster, left his family quite soon after Sloot’s birth. [3]:18 Sloot was enrolled at a Dutch technical school, but dropped out early to work at a radio station. [3]:20 After fulfilling mandatory military service, Sloot settled in Utrecht, Netherlands with his wife. [3]:20 He worked briefly for Philips Electronics in Eindhoven, Netherlands but left this job in 1978 after a year and a half, starting his next job in Groningen at an audio and video store. A few years later he moved to Nieuwegein where he started his own company repairing televisions and stereos.

In 1984, Sloot began focusing on computer technology such as the Philips P2000Commodore 64IBM PC XT, and AT. Sloot developed the idea of a countrywide repair service network called RepaBase with a database containing details on all repairs carried out. This concept was the motivation to develop alternative data storage techniques that would require significantly less space than traditional methods.

Sloot Encoding System

In 1995, Sloot claimed to have developed a Sloot Digital Coding System technique that could store an entire feature film in only 8 kilobytes. For comparison, even with the most modern techniques, a very low-quality video file normally requires 10,000 times more storage space, and a higher quality video file could require 175,000 times more data.

In 1996, Sloot received an investment from colleague Jos van Rossum, a cigarette machine operator. The same year, Sloot and van Rossum were granted a 6-year Dutch patent for the Sloot Encoding System, naming Sloot as inventor and Van Rossum as patent owner.

Despite the apparent impossibility of the encoding system, there were investors who saw potential. In early 1999, Dutch investor Marcel Boekhoorn joined the group. In March 1999, the system was demonstrated to Roel Pieper, former CTO and board member of Philips. Pieper resigned in Philips in May 1999 and joined Sloot’s company as CEO, which was re-branded as The Fifth Force, Inc.[1] The story – including an account of a believable demonstration of the technology – is told in modest detail in Tom Perkins‘ 2007 book Valley Boy: The Education of Tom Perkins.

Perkins, co-founder of the Silicon Valley venture capital firm Kleiner Perkins, had agreed to invest in the technology when Sloot died. Perkins and Pieper would have proceeded after Sloot’s death, but a key piece of the technology, a compiler stored on a floppy disk, had disappeared and despite months of searching was never recovered.


On July 11, 1999 Sloot was found dead, in his garden[2] at his home in Nieuwegein of an apparent heart attack.[1] He died one day before an attractive deal was signed with Roel Pieper, former CTO and board member of Philips.

The family consented to an autopsy, but no autopsy was performed. Sloot left behind his wife and three children.
