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. About
