Picture Quality Analysis

The PQA500 is the latest-generation Picture Quality Analyzer built on the reputation of Tektronix Emmy Awardwinning PQA200/300. Based on the concepts of the human vision system, the PQA500 provides a suite of repeatable, objective quality measurements that closely correspond with subject human visual assessment. These measurements provide valuable information to engineers working to optimize video compression and recovery, and maintaining a level of common carrier and distribution transmission service to clients and viewers. Key Features : - Fast, Accurate, Repeatable, and Objective Picture Quality Measurement - Predicts DMOS (Differential Mean Opinion Score) Measurement - Variety of HD Video Formats (1080i, 720p) and SD Video Formats (525 or 625 ) - Makes Picture Quality Comparison across Different Resolutions from HD to SD, or HD/SD to CIF - User-Configurable Viewing Condition and Display Models for Reference and Comparison - Attention/Artifact Weighted Measurement - Automatic Temporal and Spatial Alignment - Easy Regression Testing and Automation with XML Scripting - Multiple Results View Options - Optional SD/HD SDI Interface for Capturing Video - Pre-Installed Sample Reference and Test Sequences    Specsheet Tektronix PQA-500

Vclips are a diverse set of short video clips designed to test video encoders and decoders to the limits of their abilities. Key Features : - Test :Sub-QCIF,QCIF, CIF, D1, HD (720p and 1080i) - Night Time, Areas of High Contrast, Sharp Borders, Uniform Areas, Bright and Dull Colors - People, Buildings, Vehicles, Trees, Landscapes, Clouds, Water and Synthetic Objects - Movement: Fast, Slow, Uniform,Random, Multiple Moving Objects Also Pan, Zoom and Rotate - Precisely Defined Motion, Bright Colors, Dull Colors, Lines, Patterns and Grids    Specsheet Tektronix Vclips

The PQA300 Picture Quality Analysis System analyzes picture quality with repeatable, objective measurements that directly replicate subjective human visual assessments. These measurements provide invaluable information for engineers working to optimize video compression without compromising picture quality. Key Features : - Fast, Accurate and Repeatable Objective Picture Quality Measurements - Human Vision System Model, JNDmetrix - PQR Measurement - PSNR Measurement - PSNR Difference Maps - Tabular Frame-by Frame and Graphical Results - Choice of Tektronix- or User-supplied Reference Test Sequences - Measures Impairments Relative to Reference Video    Specsheet Tektronix PQA-300
