Picture Quality Analyzers

Full Reference Picture Quality Analyzers to Improve Your Video Quality

The true measure of any television system is viewer satisfaction. Based on the concepts of the human vision model, Tektronix Picture Quality Analyzers provide a suite of repeatable, objective quality measurements that closely correspond with subjective human visual assessment.

Picture Quality Analyzers are used for the design, evaluation and test of the encoding, transcoding and decoding processes. HDMI testing is critical in today’s consumer electronics like Set Top Boxes and Blu-Ray players which output video through an HDMI interface with HDCP encryption. The PQA600B uniquely decodes the HDCP protocol, and enables video quality performance comparisons on a range of consumer electronics.

They can also be used for installation, verification and trouble-shooting of each block of a video system because it is video technology agnostic; any visible differences between video input and output from processing components in the system chain can be quantified and assessed for video quality degradation.

Understanding PQR, DMOS and PSNR Measurements

This application note covers these various measurement aspects and how to address quality issues during the transition.

Picture Quality Measurement for Video Applications

This application note focuses on the issues video engineers face when developing and/or evaluating an algorithm, device or video signal path; and the objective picture quality measurement solutions Tektronix® provides to support those requirements.

Objective Measurements and Subjective Assessments Application Note

By using the PQA500 video, content providers can evaluate the various compression and delivery formats to ensure the best possible picture quality of the program.

Perceptual-Based Objective Picture Quality Measurement

This application note covers how to address potential impairments in video content (caused by various devices) in order to ensure that the content reaching end-consumers creates an engaging viewing experience.

High Definition Analog Component Measurement

Despite the benefits of digital signal processing, the final signal received by the customer is still converted to an analog signal for display on a picture monitor. With the proliferation of a wide variety of digital devices - set-top boxes, Digital Versatile Disk (DVD) players and PC cards - comes a wide range of video formats beside the standard composite output. It is therefore necessary to understand the requirements for measuring analog component High Definition (HD) signals in order to test the performance of these devices.
