.Introduction

The term fractal was coined by mathematician Benoit Madelbrot in 1975, "the Latin verb frangere means to break to create irregular fragments."

Credit for the first practical fractal compression system goes to Michael Barnsley, also a mathematician, who patented the technology in 1987. Using the image itself as the codebook, fractal compression reduces irrelevant and redundant image data so less storage space is needed to manage digital video. In any sequence of images, blocks containing similar patterns are repeated. A fractal algorithm encodes these blocks into data, or "fractal codes". When images are viewed; fractal code containing matching blocks of the original are remapped back into the correct image location. Self-similar blocks are reused during this decoding process.

TRUDEF™ is a video codec based on VDK3 fractal compression which is entirely different technology than Discrete Cosine Transform (DCT) common in video compression today. The modern successor to TMMI's VDK SoftVideo of the 1990's, TRUDEF™ is designed for native (non scaled) high resolution video for the Digital Cinema and Home Theater markets.

TRUDEF™ is engineered for high quality playback of video in the 24 bit RGB/YUV 444 color space via file based distribution on inexpensive commodity SATA3 hard drives or optical media rather than lower quality streaming.

Most commonly used video distribution codecs operate in YUV 4:2:0 color which downsamples, discarding color data to reach high compression ratios at the cost of leaving a "washed out" appearance.

By displaying video in RGB/YUV 4:4:4 color encoded with 2x2 pixel blocks TRUDEF™ offers viewers a truly superior viewing experience.
