On June 18, 2007, Symmetricom announced the new Q-400 IPTV Probe. The probe delivers carrier class, cost-effective and scalable end-to-end network performance visibility and quality assurance for service providers offering triple play services, including IPTV and VoIP. It enables quality of service (QoS) assurance for the core network and quality of experience (QoE) using Symmetricom's V-Factor to provide visibility to IPTV service quality just as a user is experiencing it in real time.
The new Q-400 monitors up to 400 SD or HD H264 IPTV streams and up to 10,000 VoIP streams in parallel in full passive mode. Scoring of streams is presented with the familiar Mean Opinion Score (MOS) for VoIP (ITU G107 Model) and for IPTV in the V-Factor MOS score, similar to the MPQM Model.
