  • 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 (116 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.

  • Precomp: More Compression for your Compressed Files (3 Comments)

    So many of today’s files are already compressed (using old, outdated algorithms) that newer algorithms don’t even get a chance to touch them. Christian Schneider’s Precomp comes to rescue by undoing the harm.

H.264 Evolution Continues: 1080p Imagery at 1.8Mbps

Posted by Sachin Garg on 1st July 2005 | Permanent Link

In July 2005 issue of Nikkei Electronics Asia reports that at NAB2005, the video technology show held in Las Vegas from April 16 to 19, 2005 there were a number of new coding technologies presented.

The major entry was H.264/Moving Picture Coding Experts Group Phase 4 Advanced Video Coding (MPEG-4 AVC), or just H.264 for short. Broadcasting, communications and next-generation optical discs using the new coding technology are expected to enter mainstream commercial use in 2005 as development accelerates.

NTT Cyberspace Laboratories of Japan offered one of the highest compression ratios for non-realtime processing. In realtime processing, the ME6000 H.264-compliant encoding system from Modulus showed a high compression ratio, achieving a bit-rate of 5.5Mbps for a 1080i HDTV signal.
