What it does? Sentry is a comprehensive content monitoring solution that gives video service providers unparalleled visibility into network anomalies at the IP and MPEG layers to quickly identify and repair errors that degrade picture/audio quality (i.e. video freeze and loss of audio). This enables service providers to ensure viewers enjoy an optimal Quality of Experience (QoE) which reduces costly customer churn. Additionally Sentry now supports the ITU-R BS.1770 audio specification which enables video service providers to identify audio volume issues in programming and commercials giving them the information necessary to quickly fix dramatic volume changes.
