Telchemy Adds IPTV Performance Monitoring Support to VQmon Product Family

Fastest route for equipment vendors to embed real-time Video over IP monitoring

SUWANEE, GA, September 13 -Telchemy,® Incorporated, the global leader in Voice and Video over IP fault and performance management technology, announced that it has integrated IPTV performance measurement into the VQmon/SA-VM video analysis software product. VQmon/SA-VM provides the fastest route for network equipment vendors to embed real-time Video over IP monitoring into set-top boxes, head-end systems, probes, analyzers and routers. Prior to its public launch, four leading test equipment vendors have licensed VQmon/SA-VM.

VQmon/SA-VM is a highly efficient, fast and compact software agent that monitors IP based video streams in real-time, measures the time distribution of lost and discarded packets using a multi-state statistical model, examines the type of video codec, bit rate and other factors and uses a perceptual model to calculate a video transmission quality factor and an estimated VQS (MOS) opinion score. VQmon/SA-VM supports H.261, H.263, H.263+, H.264, MPEG1, MPEG2, MJPEG, MPEG4 and VC1 codecs over RTP/UDP and MPEG2 Transport/UDP protocols.

VQmon/SA-VM is able to monitor large numbers of video streams in real time, with a capacity of over 100,000 packets per second when implemented in software on a typical server platform and over 1 million packets per second when implemented in network processors or silicon. This allows test equipment vendors to build probes and analyzers that can monitor high-speed aggregate video streams, or set-top box manufacturers to add video performance monitoring into existing products with no additional hardware cost.

"Telchemy's VQmon technology has been licensed by over 26 network and test equipment vendors and is integrated into more than 50 different product lines, ranging from IP phones and residential gateways to trunking gateways, routers, probes and analyzers." said Alan Clark, Telchemy's CEO and President." "We welcome the opportunity to help IPTV service providers to deliver high-quality, reliable service to their customers and achieve rapid market success."

Network operators and system administrators use Telchemy's VQmon technology to detect, monitor and resolve call quality and network related problems for networked multi-media services, including Voice and Video over IP and to support active QoS control applications such as call admission control. VQmon/SA-VM is the first Video Performance Management software to consider the impact of time varying and transient packet impairments on perceptual quality, and to model content dependency within video streams.
