OPTICOM’s advanced architecture for perceptual Quality-of-Experience measurement, benchmarking and optimization of ABR video streaming services over fixed and mobile networks. Combines true pixel-based picture quality analysis with bit-stream analysis for accurate, standardized subjective MOS prediction in real-time.
PEVQ-S embeds a wealth of International Standards OPTICOM has co-developed, or contributed to, incl. ITU-T Rec. J.247, J.341, J.343.5/.6 (2014), P.1203 (2016). PEVQ is the only commercially available video quality metrics that has continuously been validated independently by VQEG and ITU benchmarks.
Netflix, Amazon Prime Video, YouTube, Vimeo, Zattoo and more OTT VoD services supported. Protocols include MPEG-DASH, HLS, HTTP/HTTPS (YouTube), and derivates. QUIC/TLS soon to come.
PEVQ-S can be applied in real-time on Android Smartphones, and Tablets. Other O/S supported for embedded or desktop/server use are Windows and Linux.
PEVQ-S supports full scalability from high to low video bitrates and screen sizes from 4K/UHD, HD over SD to multimedia screen sizes VGA, QCIF, and CIF. Most suitable for analyzing multi-screen programming and multi-network access.
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 uncompressed source, and is therefore able to score and benchmark competitive OTT VoD streaming services.
The novel hybrid concept allows for true device/network performance measurement of the Currently Viewed Quality (MOS-CVQ), while at the same time analyzing the Best Video Quality (MOS-BVQ) available from the server, given optimum encoding and network characteristics.
The fully performance-optimized hybrid architecture allows for FR precision of Content & Media Stream Quality Analysis (one-time calculation at the server side) to be combined with lightweight on-line Transmission and Presentation Quality Analysis at the Client Probe – thus allowing for embedded real-time MOS scoring.
PEVQ-S is the first perceptual video quality measurement to offer full time-scalability from 2 sec chunk (segment) length up to program length of several minutes, even hours. Optional support of P.1203 Pq integration. Suitable for benchmarking QoE in a long-term viewer context, not just short clips.
OPTICOM’s novel ‘Smart Streaming’ engine builds on PEVQ-S as the core for ‘per-title’ and ‘per-scene’ encoding to tailor QoE to the mobile use case – while saving up to 50% video bitrate (YouTube/H.264)! Compared to several proprietary algorithms proposed, OPTICOM apply their unique standardized metrics for optimization at the encoder and diagnostics at the client, ensuring network-wide verified QoE.

SVA helps set guidelines for members to abide by in categories such as QoE Industry Guidelines, where we look forward to contributing with our knowledge and innovations for perceptual analysis for QoE, and presenting development progress within International Standards Organisations.read more
CONNECT magazine‘s 2018 benchmark of German networks puts Broadband Providers and Streaming-Portals through their Paces: Zafaco and OPTICOM test more Video Streaming Services than ever before.
German operator 1&1 won in 2017, but German Telekom is once again top of CONNECT magazine‘s new 2018 benchmark of German networks. Tested by zafaco GmbH and backed by OPTICOM GmbH‘s POLQA and PEVQ-S MOS tools for voice and video streaming benchmarking, this year‘s test analyzed more video streaming services than ever before: Amazon, Facebook, Netflix, YouTube, Zattoo and public TV ZDF. With 48 test sites all over Germany and about 4.4m measurements carried out during May and June 2018, the annual CONNECT test, now in it‘s 9th year, delivers again comprehensive QoE insights of Germany‘s network infrastructure...read more
