Sloot Digital Coding System Facts for Kids (2024)

The Sloot Digital Coding System is an alleged data sharing technique that its inventor claimed could store a complete digital movie file in 8 kilobytes of data — violating Shannon's source coding theorem by many orders of magnitude. The alleged technique was developed in 1995 by Romke Jan Bernhard Sloot (27 August 1945, Groningen– 11 July 1999, Nieuwegein), a Dutch electronics engineer. In 1999, just days before the conclusion of a contract to sell his invention, Sloot died suddenly of a heart attack. The source code was never recovered, and the technique and claim have never been reproduced or verified.

Background

Sloot was born the youngest of three children. His father, a school headmaster, left his family quite soon after Sloot's birth. Sloot was enrolled at a Dutch technical school, but dropped out early to work at a radio station. After fulfilling mandatory military service, Sloot settled in Utrecht with his wife. He worked briefly for Philips Electronics in Eindhoven. He 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 P2000, Commodore 64, IBM 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 data encoding technique that could store an entire feature film in only 8 kilobytes (8192 bytes). For comparison, a very low-quality video file normally requires several million bytes, and a 1080p movie requires about 3 gigabytes (3,221,225,472 bytes) per hour of playing time. As of 2022, the plain text of the Dutch Wikipedia page describing the film Casablanca occupies 29,000 bytes.

Roel Pieper, former CTO and board member of Philips, is quoted as saying (translated from Dutch):

It is not about compression. Everyone is mistaken about that. The principle can be compared with a concept as Adobe-postscript, where sender and receiver know what kind of data recipes can be transferred, without the data itself actually being sent."

Pieter Spronck rebuts Pieper's codebook analogy by pointing out that Sloot claimed his invention was capable of encoding any video, not only those videos composed from a particular finite set of "recipes".

In the [Sloot Digital Coding System], it is claimed that no movies are stored, only basic building blocks of movies, such as colours and sounds. So, when a number is presented to the SDCS, it uses the number to fetch colours and sounds, and constructs a movie out of them. Any movie. No two different movies can have the same number, otherwise they would be the same movie. Every possible movie gets its own unique number. Therefore, I should be able to generate any possible movie by loading some unique number in the SDCS.

Think of it: by placing the right number in the SDCS, I can not only get Orson Welles' Citizen Kane — I can get Citizen Kane in colour! Or Citizen Kane backwards! Or Citizen Kane where the credits misspell the name of Everett Sloane[!...] Or Citizen Kane where Charles Foster Kane is replaced by Jar Jar Binks!

How many movies are possible that are variations on Citizen Kane? More than fit in a number of one kilobyte, I can tell you.

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 Pieper. Pieper resigned from Philips in May 1999 and joined Sloot's company as CEO, which was re-branded as The Fifth Force, Inc. The story — including an account of a demonstration in which Sloot apparently recorded and replayed a randomly selected 20-minute cooking program on a single smartcard — is told in modest detail in Tom Perkins' 2007 book Valley Boy: The Education of Tom Perkins.

Death of Sloot

On July 11, 1999, Sloot was found dead, in his garden at his home in Nieuwegein, of an apparent heart attack. He died one day before the deal was to be signed with Pieper. The family consented to an autopsy, but none was performed.

Perkins, the 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.

FAQs

Who invented digital coding? ›

Who is Ada Lovelace? She has been called the world's first computer programmer. She created the world's first machine algorithm for a primitive computing machine that only existed on paper. Lovelace, known as the “Enchantress of Numbers,” was also a brilliant mathematician.

How does digital coding work? ›

Digital coding, also known as digital languages, is the process of using binary digits to represent letters, characters and other symbols in a digital format. There are several types of digital codes widely used today, but they use the same principle of combining binary numbers to represent a character.

What was the first digital code? ›

How does a digital code work? ›

From a technical point of view, digital game codes work through a combination of cryptography, databases, and digital rights management (DRM) systems to ensure that a legitimate copy of a game is provided to the user. Game publishers generate unique alphanumeric digital codes for each copy of their game.

What is an example of a digital code? ›

Digital Code:

Take the letter “A.” when an “A” is typed into a computer, it is immediately translated into a string of 0's and 1's (called a digital code). The digital code for “A” is “01000001.” Every letter of the alphabet has its own digital code. The code for “C” is “01000011.” And the code for “T” is “01010100.”.

Why do we use digital codes? ›

Digital codes are sequences of symbols used to represent information in digital form. These codes are essential in various applications, including computing, telecommunications, and digital electronics.

Who first invented coding? ›

Her scientific work, which is outstanding – regardless of the person behind it. About a century before Konrad Zuse designed the first programmable computing machine, in the 1840s, Ada Lovelace wrote the first computer programme in the world.

Who invented digital computing? ›

John Vincent Atanasoff is known as the father of the computer. With the help of one of his students Clifford E. Berry, in Iowa State College, during the 1940s, he created the ABC (Atanasoff-Berry Computer) that was the first electronic digital computer.

Who invented basic coding? ›

Who is the father of computer coding? ›

Babbage is sometimes referred to as "father of computing." The International Charles Babbage Society (later the Charles Babbage Institute) took his name to honor his intellectual contributions and their relation to modern computers.
