Telchemy Awarded Two New VoIP and IPTV PatentsTMCnet Contributing Editor Voice and VoIP performance manager Telchemy announced on Wednesday that the United States Patent and Trademark Office awarded the company two additional patents for its VoIP and IPTV (News - Alert) performance monitoring and analysis technology.
The patents allow for service quality monitoring systems that estimate subjective quality, also known as Quality of Experience (QoE) for VoIP, 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. Patent US 7,075,981, dubbed "Dynamic Quality of Service Monitor," covers VoIP and IPTV performance monitoring systems that represent the effects of the relative temporal location of transmission impairments on user perceived quality.
"Per-Call Quality of Service Monitor for Multimedia Communications System," patent US 7,058,048, covers VoIP and IPTV performance monitoring systems that measure call quality at discrete time intervals and combine these to form overall perceptual quality scores for each call.
"Telchemy continues to grow and innovate in this rapidly expanding marketplace," said Alan Clark, Telchemy's CEO and president in a statement. "These new patents illustrate our commitment to keeping our products on the leading edge of IP communications technology."
Today's news follows WildPackets announcement back in April about it integrating Telchemy's VQmon/SA into its OmniAnalysis Platform to offer VoIP analysis and call quality monitoring.
Telchemy's VQmon/SA will offer in-depth media stream analysis and problem diagnosis of VoIP services for the OmniAnalysis Platform. This will enable WildPackets to better serve enterprise customers that are incorporating voice in their networks.
