Perceptual Evaluation of Video Quality, combining true pixel-based picture quality evaluation with bit-stream analysis for fast and accurate subjective MOS prediction.
PEVQ-S is the first perceptual video quality measurement to offer full time-scalability from 2 second chunk (segment) length up to program length of several minutes, even hours. Suitable to benchmark QoE in a long-term viewer context, not just short clips.
PEVQ-S supports full scalability from high to low video bitrates and screen sizes (from HD over SD to multimedia screen sizes VGA, QCIF, and CIF). Suitable to analyze multi-screen programming and multi-network access.
PEVQ-S embeds OPTICOM’s advanced PEVQ algorithm, the only video quality metrics in the market that was independently benchmarked by several VQEG tests and standardized under ITU-T Rec. J.247.
While PEVQ-S has been extended for longer measurement durations, full J.247 backward compatibility is maintained to calculate P.910 compliant MOS scores for standardized 10 second sequences.
PEVQ-S scored best in the latest VQEG hybrid benchmark 2014 and is expected to be recommended for future standardization by the ITU-T.
Contrary to often applied bit stream analysis, PEVQ-S is the only FR perceptual video quality measure to truly score encoder and media stream picture quality with respect to the studio master, and thus able to score and benchmark competitive OTT offerings.
The novel hybrid concept allows for the actual measurement of true device performance, while at the same time analyzing the best possible QoE depending on optimum encoding and network characteristics.
The fully performance-optimized hybrid architecture allows for FR precision of Media Stream Quality Analysis (one-time calculation at the server side) to be combined with time critical light-weight performance at the Client Probe – thus allowing for embedded real-time MOS scoring.
