  • 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.

MPEG LA Issues Expanded AVC Patent Portfolio License

Posted by Sachin Garg on 17th November 2005 | Permanent Link

MPEG LA previously announced on January 27, 2005 that this expansion would be forthcoming. The current royalty rates that apply to products which use one or more AVC profiles also apply to products that use FRExt/AVC.

The AVC Patent Portfolio License is offered for the convenience of AVC users enabling them to obtain coverage under essential patents owned by multiple patent holders in a single license as an alternative to negotiating separate licenses. MPEG LA’s objective is to provide worldwide access to as much AVC essential intellectual property as possible for the benefit of licensees (new patent holders and essential patents may be added at no additional royalty during the current term of the License). Therefore, any party that believes it has a patent which is essential to FRExt/AVC or other part of the AVC/H.264 standard and would like to participate in the AVC Patent Portfolio License is invited to submit its patent(s) for an evaluation of essentiality by MPEG LA’s patent experts and inclusion in the License if determined to be essential.
