Telchemy Debuts SQlive, a Groundbreaking Application for Monitoring IPTV

By Michelle Robart, TMCnet Editor


Telchemy (News - Alert), a global innovator in IPTV and Voice over IP (VoIP) performance management technology, Wednesday announced a revolutionizing IPTV and IP Videoconferencing performance monitoring application, SQlive.
 
Supported by Telchemy’s industry-leading VQmon/HD performance analysis software, SQlive is unique in its ability to assess the performance of scrambled/ encrypted IP Video streams, and produces Video MOS scores and a wide range of diagnostic metrics.
 
“We are pleased to introduce SQlive, the latest in our real-time video analysis product range,” said Alan Clark (News - Alert), Telchemy’s CEO and president. “SQlive is ideal for both IPTV and digital cable system performance management, and provides a strong solution for IP Videoconferencing and HD Telepresence (News - Alert).”
 
Due to its compact size, SQlive can be easily integrated into IP set-top boxes, but it is still powerful enough to monitor large numbers of high-definition IPTV (News - Alert) streams.
 
SQlive examines scrambled and unscrambled IPTV streams carried over MPEG Transport or RTP, and IP Videoconferencing/ HD Telepresence streams carried over RTP or SRTP. It is also able to automatically identify video frames and recognize the type of video content.
 
This creates a rich range of metrics and accurate QoE metrics, including:
 
-- Video MOS scores that incorporate the effect of packet impairments on different video     frame types, GoP error propagation, video bandwidth, video codec, bandwidth limitation and other factors;
 
-- Video content descriptors, including data on levels of detail and motion;
 
-- Video content alerts, which detect if content is blank or frozen;
 
-- I/B (News - Alert)/P frame statistics, including loss rates within each type of frame, bandwidth usage and other key data, and;
 
-- Video degradation factors, which highlight the key sources of performance degradation.
 
SQlive is a “drop-in” application that can be easily incorporated into an IP STB with virtually no software integration required. This powerful application can also analyze large numbers of IPTV streams in real-time, for IPTV probe or head-end applications.
 
Telchemy is a global innovator in Voice and Video over IP Performance Management Technology with its VQmon, DVQattest and SQmon families of service quality monitoring and analysis software products. Telchemy is the world's first company to provide Voice and Video IP performance management technology that considers the effects of time-varying network impairments and has led the development of VoIP performance management protocols within the industry. 
 
Founded in 1999, the company has products deployed worldwide and markets its technology through leading networking, test and management product companies.
