mpeg-4
(foldoc) | MPEG-4
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-4 aac main profile
(foldoc) | MPEG-4 AAC Main Profile
A successor of
MP3 allowing transparent coding at data rates of 70-75% of
that of MP3. It is very different from MP3, only used
MDCT, no subband coding. It is much more complex that
MP3 and MPEG-2 AAC Low Profile.

mpeg-4 aac ssr
(foldoc) | MPEG-4 Advanced Audio Coding Scalable Sampling Rate
MPEG-4 AAC SSR
(MPEG-4 AAC SSR) An AAC
flavour supporting different qualities for different targets.
One stream can contain up to 3 streams for 11.025 kHz (Stream
1), 22.05 (Stream 1 and 2) and 44.1 kHz (all 3 Streams)
sampling frequency. Quality is between Low Profile and Main
profile. See also JPEG-2000.
