Telchemy Awarded Two New Patents in VoIP and IPTV Performance Management

July 27, 2006 – Telchemy, developer of voice and video over IP fault and performance management technology, has announced that the United States Patent and Trademark Office has awarded the Company two additional patents for their VoIP and IPTV performance monitoring and analysis technology.

The two new patents embrace service quality monitoring systems that estimate subjective quality, also known as Quality of Experience (QoE) for Voice over IP, IPTV and Videoconferencing services. The algorithms described in these patents provide more accurate and stable performance metrics in the presence of time varying and transient impairments.

Over 70 equipment manufacturers have integrated Telchemy’s VQmon IP performance monitoring software into almost 100 different product lines with over four million units of VQmon licensed. VQmon has been widely adopted within the test and measurement industry, and is used by over 25 VoIP test equipment and seven IPTV test equipment manufacturers.
