VQmon is unique in analyzing both scrambled and unscrambled IPTV streams carried over MPEG Transport or RTP, and supports common FEC and retransmission schemes. VQmon automatically identifies video frame types and recognizes the type of video content, producing a rich range of metrics and accurate QoE measurements. Metrics generated include:

• 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/P frame statistics, including loss rates within each type of frame, bandwidth usage and other key data
• Video degradation factors, which highlight the key sources of performance degradation

VQmon is licensed for integration with third party software, or can be provided as a turnkey performance monitoring application, SQlive, which is designed for easy installation in IPTV set-top boxes or mobile handsets.
