Fastest route for equipment vendors to embed real-time Video over IP
monitoring
Suwanee, GA --Telchemy,(r) 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.
