ATEME
delivers H.264/MPEG4-AVC technologies for end-to-end streaming
solutions.
Encoders, decoders and streaming IP integrated with 3rd party
DRM has been demonstrated at IBC (September 2004, Amsterdam).
Our technology is available and already adopted by customers,
in Broadcast, Broadband and Corporate markets, in live SD main
profile encoders and in IP Set-Top Boxes for H.264 DSP
decoder.
Our
encoders/decoders strictly follow ISO/IEC 14496-10 standard,
implementing all tools for the very best video quality.
Benchs achieved by independent experts show ATEME's solutions
as the fastest and highest quality solutions.

H.264
technology overview
H.264
/ MPEG-4 Advanced Video Coding / MPEG-4 ISO 14496 part
10 boasts high quality for low bitrate and overcomes the
bandwidth limitation while addressing the needs for high
quality video.
This new compression standard features enhanced
compression performance while providing a video
representation which addresses “conversational”
(video telephony) and “non-conversational” (storage,
broadcast or streaming).
This
standard is declined in 4 profiles:
- Baseline
- Main
- Extended
- High
- coming soon
The
main changes compared to MPEG-4 (part 2) are:
- Integer
transform
- Context
Adaptive Coding (CAVLC, CABAC)
- Enhancement
of every steps
- More
processing power for an enhanced quality
Encoding
principle is the following:
-
Multiple
reference frames
are used for motion
compensation step.
-
Integer
transform
prevents mismatch between encoder
and decoder.
-
Quantization
is done with Non constant step increment.
-
Context
modeling (Context adaptive coding)
provides conditional probability of the coding
words.
-
Deblocking
filter
allows artifacts removal on
reference frames.
