WMV stands for Windows
Media Video -- developed and controlled by Microsoft. WMV is a generic name
of Microsoft's video encoding solutions and doesn't necessarily define the technology
what it uses -- since version 7 (WMV7) Microsoft has used its own flavour of
MPEG-4 video encoding technology.
DivX video format is originally based on hacked
Windows Media Format 11 adds support for HD video up to 1080P. WMF 11 runs
only on Windows XP and Vista.
Additional information is available on Microsoft
Windows Media page.
A video compression standard planned for late 1998. MPEG-4
extends the earlier MPEG-1
and MPEG-2 algorithms with
synthesis of speech and video, fractal compression, computer visualisation and
artificial intelligence-based image processing techniques.
MPEG.ORG is an excellent source for additional
information on MPEG format and usage.
