Tektronix provides an automated method for picture quality assessment

Tektronix has announced the PQA500 Picture Quality Analyzer, a next-generation picture quality analysis (PQA) tool.

Incorporating eight new Tektronix patents and embodying a comprehensive human vision model, the PQA500 provides a complete suite of measurement and diagnostic tools for picture quality analysis, including full support for HD formats.

Video developers and broadcasters can quantify subjective video responses with the PQA500, enabling them to tune their video offerings for differences in format and delivery mechanisms. This enables them to consistently produce an optimal customer viewing experience.

The system provides an automated method for practical, efficient and reliable picture quality assessment between HD/SD and low-resolution clips like CIF and QVGA for CODEC design and conformance test applications.

The unit includes integrated signal acquisition, manual and automated measurements through XML scripting, no preset limit to clip lengths or file sizes and no need for a trigger pattern in the clip to align test to reference video.
