Symmetricom and Sagem Partner for IPTV QoE

Symmetricom announced it is partnering with Sagem Communications (SAFRAN Group), a worldwide leader of IPTV set-top boxes (STBs) with 2 million units shipped before year-end, to trial Symmetricom's V-FactorR solution into SAGEM IPTV STBs to gain visibility into the quality of experience of IPTV customers. By embedding V-Factor, an industry leading solution that correlates network and content metrics to accurately monitor the quality of consumers' video experience, service providers gain insight into IPTV and other real time multimedia services directly from homes that utilize SAGEM STBs. The joint solution will initially launch with beta trials at a service provider in France.

Traditional methods involving Quality of Service (QoS) that is assessed in the core network must be paired with Quality of Experience (QoE) metrics to achieve end-to-end performance monitoring. With Symmetricom's V-Factor embedded in STBs, service providers are able to monitor QoE from a customer's point of view. Based on the Moving Picture Quality Metrics (MPQM) model adapted specifically for end-to-end video quality scoring, V-Factor is the first perceptual video quality solution that correlates both network and content impairments. Symmetricom's QoE solutions provide a reliable benchmark (e.g., a MOS score) familiar to most CSPs. This enables service providers to diagnose the perceptual impact of video quality impairments that are introduced by transmission over an IP network and/or by artifacts that arise from various encoding methodologies.

"We are confident that the trial of our combined solution will meet the performance and QoE monitoring expectations of our service provider customers as they seek to grow and improve their IPTV and other IP-based video offerings," said Yves Cognet, chief technology officer for Symmetricom's QoE Assurance Division. "Our goal is to demonstrate the benefits of an end-to-end solution that includes real time monitoring from inside a customer's home."
