The TVQM measures packet loss and discard rate, burst/gap statistics, FEC effectiveness, TR 101 290 MPEG transport metrics and jitter. The video stream metrics include I, B, P frames received, I, B, P frames impaired, Group of Picture structure and video codec type, bit rate and frame size.
TVQM perceptual quality metrics include video service transmission quality, video and audio MOS, audio-video MOS and PSNR. Telchemy uses patented perceptual models representing the impact of time varying impairments on user perceived quality to calculated MOS scores.
VQmon/SA for VoIP and VQmon/SA-VM for IPTV offer core analysis functions for analyzers and probes, and are also uses for traffic analysis and SLA monitoring in routers. VQmon/EP is integrated into IP phones and gateways, and offers real-time feedback on call quality to network management and call management systems.
