Sentry ABR Active Video Quality Monitor w/ options: 1G = Throughput of 1 Gb/s; XG-SR = Adds 10 GbE interface and short range SFP

The Tektronix VNM-SABR is a Sentry ABR Video Quality Monitor.

Supports up to 250 top manifests

Supports Apple’s HTTP Live Streaming, Adobe's HTTP Dynamic Streaming and MPEG DASH Protocols with HTTP statistics

Proactively monitors all available ABR “media” and “network” from content acquisition (source) to the edge of the network

Fetches manifest files and fragments from any place on the network to simulate a subscriber’s request for content

Validates all assets, bitrate profiles and manifest files based on a highly parallel HTTP fragment fetching engine

Top level manifest file validation is used to automatically discover the sub-stream manifest URLs

Performs sub-stream manifest validation and fragment fetching in real time at the manifest-indicated rate

Alerts on any mismatch in the bitrate of the sub streams; missing segments (HTTP errors); and excessive segment-fetching latency

Reports on the availability of all input manifests (programs) over the network, and their sub streams in the familiar Sentry-product style

Supports both 1 GbE and 10 GbE interfaces allowing Sentry ABR to be placed throughout the network for maximum ABR monitoring coverage
