Hi pals,
the german computer technology magazine c't writes:
{-} LuraTech (formerly related to the german aerospace technology company), creator of wavelet image compression technology applications (LuraWave, LuraDocument, JPEG2000) is broke. Bad for us: Probably no LuraVid codec under development anymore. Does anyone know other wavelet based codecs (besides Pegasus PICVideo)?
{+} ISO and ITU-T are discussing a new compression standard called H.26L: Based on H.261 and H.263 (predecessors of MPEG), but offers motion analysis down to 1/8th pixel, 7 possible DCT square sizes down to 4x4; a variant using CABAC (an adaptive entropy coder based on arithmetic coding, better than Huffman) shall provide the same quality as MPEG-4 at half the bitrate in current tests. The standard is expected to be published around the middle of this year, and Microsoft is expected to be one of the first codec developers.
