  • 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.

NASA to Deliver Real-Time High Definition Video and Images From Space

Posted by Sachin Garg on 12th September 2005 | Permanent Link

LSI Logic Corporation announced that NASA will be leveraging the LSI Logic HDTVxpress Compressor PCI board to provide real-time high definition (HD) content creation capabilities aboard future space missions. This highly integrated and compact encoding system provides NASA with the ideal form factor to incorporate into workstations capable of capturing, broadcasting and archiving dazzling HDTV-quality images live from above the earth.

LSI Logic also worked with NASA to ensure the product meets the agency’s compliance with security, gravity and stress requirements so that it retains the quality, accuracy and speed of HD video during missions.
