Telchemy Licenses Video over IP Monitoring Software Agent

Telchemy has integrated IPTV performance measurement into its VQmon/SA-VM video analysis software product, which network equipment vendors can use 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.
