Symmetricom, Inc. (NASDAQ: SYMM) today announced its Principal Technologist for QoE Solutions, Dr. Stefan Winkler is co-chairing, with VSF Director and AT&T Laboratories� Lead Member of Technical Staff, Pierre Costa, a new Video Services Forum (VSF) activity group that will define Quality of Experience (QoE) Metrics for Video over IP. The activity group will define QoE metrics for video streams over IP transport for applications such as monitoring, troubleshooting, equipment compliance, service verification, etc. The VSF is made up of more than 50 member companies. �Given the growing need for comprehensive measurements that accurately reflect the consumers� QoE, it is important to address quality issues with the delivered video service, in particular those related to the video payload and its effects on transport losses and perceived quality,� said Symmetricom�s principal technologist, QoE Solutions, Dr. Stefan Winkler. In December 2006, the VSF Test and Measurements activity group produced a report on Recommended Video over IP Metrics, which identifies and describes metrics required to accurately characterize packet-based network performance for streaming video transport. The new VSF QoE Metrics activity group measurements will account for the consumers� Quality of Experience (QoE). Final recommendations from the group are expected by year-end 2009.
