Zoltes, a provider of test solutions for data centers, voice and video technologies, announced the launch of a new Zoltes Media Analyzer (ZMA) that provides an easy way to monitor and analyze traffic in TelePresence and video conferencing systems and services.
Offering support for latest industry standards including SIP RFC 3261, SDP RFC 2327 and ITU-T H.323 version 7 as well as ITU-T H.263 and H.264 video codecs, ZMA provides Quality of Service (QoS) measurements using MDI (News - Alert) (Quality of Video) and MOS (Quality of Voice) metrics.
The new Zoltes Media Analyzer can be used to troubleshoot multiplexed, primary and secondary video streams, including voice traffic, for TelePresence endpoints running SIP or H.323. Additionally, ZMA provides end user experience measurements and in depth protocol analysis supporting the needs of high-end video conferencing technology scenarios in service provider and enterprise environments.
ZMA directly integrates with the multichannel Zoltes Fax Monitor and Analyzer. Zoltes Fax Monitor and Analyzer monitors and/or decodes the fax transmissions over T1/ E1/ Analog and IP lines, which results in accurate demodulation and decoding of raw fax data transmissions. ZMA tracks calls across the PSTN and IP Networks and easily combines them in side-by-side analysis.
The MDI and MOS metrics allows video conferencing and telepresence system manufacturers, integrators and service providers to address the challenge associated with offering real world quality of audio and video connections to other locations in a cost-effective manner.
Due to the growing complexity of video conferencing and telepresence, manufacturers and integrators are forced to keep up with three interdependent variables: video resolution, frame rate, and bandwidth.
While telepresence systems provide the best possible video quality by maximizing both video resolution and frame rate, things are more complicated in reality. This occurs because of limitations in processing power of these systems, which forces one to decide optimizing frame rate and optimizing resolution.
“Using compression to minimize the bandwidth requirements can induce signal degradation and additional latency,” according to Zoltes. “Using compression is very important in video transmission, but excessive signal compression could lead the video quality to decrease below the acceptable customer experience level.”
Zoltes’ media analyzers allows telepresence and video conferencing systems and services vendors to fine tune and troubleshoot video and audio transmissions, dependent upon the problems they are trying to solve or the markets they are addressing, the company said.
Meanwhile a recent report by Global Industry Analysts predicts that video conferencing market is set to grow in the coming years and will become a $14 billion global industry by 2017. Zoltes’ media analyzer solution is ideally designed to tap this huge market.Rajani Baburajan is a contributing editor for TMCnet. To read more of Rajani's articles, please visit her columnist page.
