"The Sloot Digital Coding System was 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,[1] Nieuwegein), a Dutch electronics engineer.[2] 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. " From wikipedia
