|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.
|Understanding PQR, DMOS and PSNR Measurements|
This application note covers these various measurement aspects and how to address quality issues during the transition.
|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.
|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.
