Digital Video Signal Analyzer for DVI and HDMI
OverviewNI VideoMASTER, a versatile video analysis and generation test suite
for validation and production test, works with a wide variety of standards
and formats for analog and digital video. The NI VideoMASTER Digital
Video Analyzer combines an NI PXIe-6545 high-speed digital waveform
analyzer/generator, an NI PXI-2172 DVI/HDMI input deserializer and
decryption module, and NI VideoMASTER Analysis Software to deliver
a comprehensive automated test solution for digital video devices.
VideoMASTER offers easy-to-use graphical user interfaces, more
than 250 analog and digital video measurements optimized for
automated test, and seamless integration with NI TestStand test
management software for automated validation and production
environments. High-test throughput, coverage for design and
production requirements, and a relatively low cost ensure a reduced
overall ownership cost for high-performance digital video test.
Integrated Solution for Digital Video AnalysisThe VideoMASTER Digital Video Analyzer is a solution for functional
test of DVI and HDMI digital video signals that you can use to test
HDCP encrypted or unencrypted video. It is an extension of the
VideoMASTER Analog Video Analyzer that analyzes composite video,
S-video, and component video. These solutions are well-suited to
analyze video characteristics such as color bar measurements to
verify the hue and color saturation accuracy, multiburst and sweep
measurements to test the frequency response, K-factor measurements
to test uniformity of frequency response, horizontal timing for general
timing analysis, and a variety of linear and nonlinear distortions.

Fast Signal Acquisition and High ThroughputDuring initialization, VideoMASTER automatically determines the digital
video signal format (resolution and timing) and pixel encoding of the
source signal and acquires the signal accordingly. Once VideoMASTER
acquires the video signal, you can use a video image frame to perform
measurements defined by the user with the advanced signal processing
algorithms included in the software. To ensure optimal execution speed
for digital video testing, the system acquires one frame of video and
takes several measurements on the acquired frame defined by the user.
Measurement time thus becomes a function of computation time and not
the acquisition time. The result is a system that benefits from the latest
multicore processors to reduce total test time. The total test time for a
video test, digital or analog, thus consists of the acquisition time for one
frame and the time to perform the requested measurements. The latter
improves over time as the host processor increases in performance.
Hardware ArchitectureVideoMASTER uses an NI PXI-2172 deserializer and decryption module
to convert the DVI or HDMI digital serial stream to a parallel stream that
can then be acquired by the NI PXIe-6545 high-speed digital module. The
communication and data transfer between these modules is transparent
to the user and handled by the VideoMASTER Analysis Software.

Easy-to-Use Software InterfacesVideoMASTER Analysis Software is shipped with several easy-to-use
software interfaces for quick and easy configuration and measurement.
The interfaces include the following:n Interactive Video Analyzer Instrument Panel for easy debugging and
nonautomated applicationsn Measurement Locations Editor for standard or custom video signal
measurement locationsn Custom step types for NI TestStand for efficient application
development for validation and product test setups
Use the custom step types for NI TestStand to quickly develop test
sequences for new applications, including configuring typical video
parameters for test. Then easily manage pass-fail tests with the
configurable Limits Editor to ensure your video measurements meet
internal or industry standards. Use company-wide defined limit
parameters by dynamically loading limits files defined by the test
developers. You also can save limits to file for use in other test
applications, which reduces test development time and removes
potential sources of error. In addition, VideoMASTER includes an API
that features several high-level LabVIEW VIs that you can use to create
customized video analysis applications. Visit ni.com/videomasterto configure your VideoMASTER solution.
Unified Solution for Analog and Digital VideoYou can use VideoMASTER for both digital and analog baseband video
analysis with a common software interface. Configure a system to
perform analog video analysis and/or digital video analysis on various
configurations ranging from analog composite video to a complete
system including composite, S-video, and component analog video
combined with digital analysis for DVI, HDMI, or parallel ITU-R BT.656.
