End to end video quality monitoring with
Sentry® ABR is part of the Telestream end-to-end video quality and service assurance solution for monitoring OTT (Over The Top), TV Everywhere and multiscreen services. Sentry ABR provides a comprehensive and scalable monitoring solution for post-fragmented adaptive bit rate (ABR) streams and supports both 1 GbE and 10 GbE interfaces for maximum ABR monitoring coverage throughout the network.
Sentry ABR supports up to 250 top manifests which translates into a much higher monitoring capacity as each manifest can support up to 15 representations of each program. Sentry ABR proactively monitors all available ABR “media” and “network” from content acquisition (ingress) to final delivery. Sentry ABR offers ABR decryption and DRM support, which enables Quality of Experience (QoE) and Perceptual Video Quality (PVQ) measurements for decrypted and decoded video and audio content.
Manifest files and fragments can be fetched from any place on the network (e.g., origin servers or CDN caching servers) to simulate a subscriber’s request for content. Sentry ABR validates all assets, bitrate profiles, and manifest files based on a highly parallel HTTP fragment fetching engine. In addition, it supports all of the existing alert functionality and reporting capabilities offered in Sentry (including the alert dashboard, program availability and 90-day historical reporting and trending analysis). This enables proactive and comprehensive QoS and QoE monitoring of all video assets for ABR streaming. ABR issues are identified quickly and often resolved before customers are impacted.
