Video Quality Monito

Sentry® is a comprehensive video and audio quality monitoring solution for advanced video networks. It enables video service providers to deliver services with optimum quality while reducing operational expenditures.

Sentry identifies anomalies in the network at the IP and MPEG layers as well as in Quality of Experience (QoE), identifying issues including frozen video, tiling/macroblocking  and audio disruptions or audio-level issues, which represent the bulk of trouble calls from subscribers.

In addition, Sentry includes a video artifact measurement and detection capability. This makes Sentry the only solution that detects video and audio errors in digital programs while generating metrics that correlate to Mean Opinion Scores (MOS).

Sentry provides analysis tools coupled with historical data to give service providers the ability to resolve complex and intermittent problems quickly. Advanced reporting capabilities deliver reports that quickly identify the top offending programs or locations. Trending reports quantify improvements made over time. Lastly, reports can be automatically generated and forwarded by e-mail for an accurate and timely assessment of the quality of every program.
