Video headend analyzers identify video impairments to ensure a high-quality delivery of advanced digital video for cable operators, which aids in reducing operating costs and customer churn. The Q-1000 was recently awarded an 'Excellent' Rating in Broadband Gear Report's Diamond Technology Reviews.

Video headend analyzers are a critical part of Symmetricom's V-FACTOR® Quality of Experience (QoE) platform. The V-FACTOR platform empowers telco and cable operators to monitor key sources of potential video and audio impairments by providing a scalable solution that accurately assesses a consumer's video quality experience. The video headend analyzer, in conjunction with Symmetricom's network probes, software agents, and NOC software, form a comprehensive end-to-end video QoE solution. The headend analyzer performs specialized functionality at the headend, while Symmetricom's network probes and software agents monitor other network nodes to ensure accurate identification of video quality issues throughout the video delivery chain. This provides an understanding of video quality services enabling reduced costs through efficient diagnosis and decreased customer churn.
