National Instruments has
introduced the new NI Digital
Video Analyzer, which automates
a wide range of tests for the latest HDMI
sources such as set-top boxes, Blu-ray
Disc players and DVD players. The
analyzer features configuration-based
test steps that automate measurements
of HDMI features including 3-D video,
HDMI 1.4 protocol and picture quality
analysis. With hardware based on the NI
PXI Express platform and software
designed for multicore computing,
engineers can use the NI Digital Video
Analyzer to achieve high-performance,
high-precision measurements of HDMI
content in a fraction of the time required
by traditional video test solutions.
The NI Digital Video Analyzer
combines with NI Picture Quality
Analysis software to precisely measure
streaming audio and video quality and
eliminate challenges inherent with
subjective operator inspection. Using the
system's variety of measurements,
engineers can analyze streaming video
for defects such as macroblocking, stuck
frames and audio drops, which singleframe
static image analysis cannot
detect. Engineers also can use the
system to conduct higher performance
measurements of total picture quality
with pixel-to-pixel reference tests such
as peak signal-to-noise ratio and
structural similarity.
The NI Digital Video Analyzer also
supports HDMI protocol tests including
InfoFrames, consumer electronics control
(CEC) messaging, extended display
identification data (EDID) emulation and
hot plug detect (HPD) events.
