  • Bijective BWT (7 Comments)

    David Scott has written a bijective BWT transform, which brings all the advantages of bijectiveness to BWT based compressors. Among other things, making BWT more suitable for compression-before-encryption and also give (slightly) better compression.

  • Asymmetric Binary System (113 Comments)

    Jarek Duda’s “Asymmetric Binary System” promises to be an alternate to arithmetic coding, having all the advantages, but being much simpler. Matt has coded a PAQ based compressor using ABS for back-end encoding. Update: Andrew Polar has written an alternate implementation of ABS.

iTnews: Dolby to showcase DRM technology, Digital Cinema based on Jpeg2000

Posted by Sachin Garg on 21st October 2005 | Permanent Link

iTnews: To ward-off bootleggers in the motion picture industry, Dolby Laboratories is developing digital rights management software for servers used by theatre owners that are swapping out celluloid for digital projector and IT networks.

Dolby’s servers run on Linux. With digital cinema technology maturing quickly, both software and hardware upgrades are already in the works. Among the fixes already known is an upgrade from the MPEG compression standard to the JPEG 2000 compression standard based on the digital cinema specifications finalised last summer by the Digital Cinema Initiative LLC, an industry consortium formed by the top studios to develop digital cinema standards. The group disbanded last month after completing the task.

More software upgrades may be in order if and when the movie industry moves from 2K (2048 x 1080) resolution projectors to 4K (4096-by-2160) in theatres. These 4K projectors display images at more than four times the resolution of current high-definition projectors. The server processor speeds would have to increase from today’s 250 megabytes. It’s not known if and when that would happen.
