  • 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    So many of today’s files are already compressed (using old, outdated algorithms) that newer algorithms don’t even get a chance to touch them.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.

  • On2 Technologies is Hiring

    There aren’t too many companies working on cutting edge codecs, and of those few this one is hiring. Best of luck.

More news on TI Davinci Codecs

Posted by Mark Nelson on 16th March 2006 | Permanent Link

Based on the current barrage of stories in industry rags, it looks like TI is pretty close to shipping their highly-touted DaVinci modules for their C54/C55/C64 DSPs. The stuff they are offering right now includes:

MP3 Decoder C54x
AAC Encoder/Decoder C55x
MP3 Encoder/Decoder C55x
AAC Encoder/Decoder C55x
WMA9 Encoder/Decoder C55x/C64x
JPEG Encoder/Decoder C64x
On Screen Display Lib C64X
H.263 Encoder/Decoder C64X
MPEG2 Encoder/Decoder C64X

This is a pretty useful set of codecs, I know there’s plenty I could do with them. The downside is that TI apparenlty has decided their DPS software needs to be a profit center, so they’re charging $50K/seat for developer’s tools and royalties start at $2.20/part. Ouch.
