Telchemy Inc. announced a new Video Module for its VQmon family of call quality monitoring and analysis software. The VQmon/SA-VM (Video Module) adds real time monitoring and diagnostics for streaming video and next generation video conferencing applications to the company's VQmon/SA (Stream Analysis) product.

VQmon/SA technology is embedded in mid-stream network routers and switches and in VoIP test equipment to provide fast, accurate, real-time analysis of VoIP calls. The software generates call quality and packet-related metrics, including listening and conversational quality scores, and detailed diagnostic information on the severity and distribution of packet loss, discards and jitter. VQmon/SA supports the IETF RFC 3611 (RTCP XR) Protocol and the new QoS reporting protocols for ITU's H.323, H.248 and G.799.1 standards.

Meanwhile, the new module supports the analysis of ISO MPEG standards and ITU H.26x video codecs and features Video Transmission Quality Metrics (V factor) and Video Quality Scores (VQS) in addition to the core VQmon/SA metrics. According to Telchemy, V factors provide network administrators with an easy to use view of the IP channel's capability to support video transmissions, while the VQS provides a codec dependent objective quality score ranging from 1 to 5, analogous to a MOS score.

"By adding video support to VQmon, Telchemy now provides its customers with Multimedia Fault and Performance Management covering streaming video, video conferencing, in addition to narrow and wide band voice applications," commented President and CEO Alan Clark. "We now offer our customers a comprehensive set of Fault and Performance Management monitoring solutions for all their real-time multimedia needs."

The new VQmon/SA-VM, v2.2, will be available in late April.
