The Q-400 can passively or actively monitor voice and video quality for service providers offering triple-play services. It can assess digital video and voice streams for quality as people perceive it. While monitoring content, the Q-400 detects source quality impairments, encoding/decoding effects, and network-related impairments in unicast or multicast transmissions.
The Q-400 monitors up to 400 standard-definition (SD) or high-definition (HD) IPTV streams and up to 10,000 VoIP streams. It filters content through a human vision system (HVS) model to quantify the impairments caused by packet jitter to video and voice for quality of service measurements.
