National Instruments Digital Video
Analyzer Automates Wide Range of HDMI Tests
New PXI Solution Delivers HDMI 1.4 Protocol, Embedded Audio,
3-D Video Measurements and Real-Time Picture Quality Analysis
AUSTIN, Texas June 7, 2011 National Instruments today
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 new NI Digital Video Analyzer and NI Picture Quality Analysis
software address the growing demand for test solutions that
identify perceived audio and video quality of HDMI content, said
Steve Warntjes, director of modular instruments research and
development at National Instruments. These tools deliver reliable
measurements for HDMI-enabled multimedia devices and eliminate the
challenges associated with manual operator inspection.
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
systems variety of measurements, engineers can analyze streaming
video for defects such as macroblocking, stuck frames and audio
drops, which single-frame 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. Such capability makes it possible for the NI
Digital Video Analyzer to simulate an LCD or HDTV and better
guarantee interoperability with other HDMI-enabled devices.
With its NI PXI Express architecture, the analyzer incorporates
solutions for multiple HDMI measurements into a single compact
solution. The instrument includes the NI PXIe-6545 200 MHz high-speed digital
I/O module, the NI PXI-2172 deserializer and decryption module and
the NI PXI-7813R reconfigurable I/O FPGA
module, all of which integrate with the NI Video Measurement Suite
and NI Picture Quality Analysis software to offer engineers a fully
integrated solution for automated testing of HDMI sources.
