New Test Methodology, Advanced Video Coding (AVC/H.264) and Scalable
Video Coding (SVC)
The Motion Imagery
Quality (MIQ) Metrology Project works with MPEG in the development of
next generation video coding and other components of high quality imagery
systems. Recent contributions include a international collaborations to
test various proposed technologies for Advanced Video Coding (AVC/H.264)
and for Scalable Video Coding (SVC). In preparing such recent tests, the
MIQ Lab has developed new test methodology for video compression on multimedia
and high definition platforms.
- In December 2003,
MPEG concluded the AVC Verification Tests. These tests verified that
AVC/H.264 achieves a doubling of compression efficiency as compared
to MPEG-2 in over 60% of the statistically conclusive tests. This work
is reported in a paper to the 2004 International Broadcast Conference.

- AVC/H.264 technology
supports compression for a great range of applications, ranging from
multimedia to standard definition TV and high definition systems. NIST
and our international collaborators have developed new test methodology
to support video quality testing in the new domains of multimedia and
high definition video. This work was reported to the 2004 SPIE Conference
on Applications of Digital Image Processing XXVII. SubjectiveAssessMethodsForMPEG-Final.pdf
- For many applications
in surveillance and security, video production, and digital cinema,
10-bit and 12-bit imagery is becoming an essential tool in retaining
video quality. The higher bit depths (10- and 12-bits) are intended
to provide greater dynamic range than the more usual 8-bit imagery that
is so common in traditional TV and in PC-based imaging. However, an
image presentation system designed to provide 10 bits of dynamic range,
may not deliver on its promise of 1000 grey levels. The MIQ Project
has recently develop metrology to determine the delivered dynamic range
of image presentation systems. An MIQ paper to the 2003 SPIE Conference
on Communications and Image Processing describes a practical measurement
method for determining delivered dynamic range. Resolution&DynamicRange.pdf
