Audio and video analysis suite

6 March 2013 Test & Measurement

National Instruments announced the company’s newest multimedia test offering – the PXIe-1491 digital audio and video analyser for HDMI, DVI and mobile devices. Designed for performance testing and high-throughput test of consumer devices such as set-top boxes, Blu-ray players, smartphones and tablets, it delivers automated, high-performance measurements to eliminate subjective manual inspection.

The instrument is shipped with NI Video Measurement Suite, a versatile test suite for analysing a wide variety of video standards. NI also offers add-ons such as AudioMASTER software, designed for in-depth audio testing including frequency response and THD, and Picture Quality Analysis (PQA) software.

PQA software delivers quality of experience (QoE) metrics such as peak signal-to-noise-ratio (PSNR) and structural similarity index metric (SSIM). In addition, it enables engineers to measure lip synch, macro blocking, dropped frames, pixelation and more in real-time by combining PXI Express technology with highly parallelised measurement algorithms.

The benefits of the PXIe-1491 extend beyond at-home consumer electronics. Applications include testing of aerospace and defence systems, automobile rear-view camera and infotainment systems, in-flight entertainment systems, video conferencing and professional audio/video equipment.
