Remote, 24 x 7 Multi-Window Monitoring System and Professional Real Time HTTP Live Streaming (HLS) Analyzer for Validating HLS Formats and Verifying MPEG Transport Stream and Audio/Video Quality. Suitable for Testing HLS Video Service Infrastructure and Real Time Monitoring of Service Content. Perfect Tool for Monitoring and Analyzing WOWZA, DVEO®, Envivio, and Elemental Transcoders.

Real time multi function streaming video and SDI analyzer for continuous reporting of stream health to supervisory systems that can make instantaneous decisions about automatically switching in alternative resources to maintain quality level and enhance user satisfaction.  Analysis modes include ETR 290, TS, broadcast, and streaming.  AI assisted functionality.

Compact (7.5 Inches Wide) IP Gateways for Reliable Delivery of any bitstream – MPEG-2, H.264, H.265, compressed or uncompressed video, or audio over private or public wired or wireless Internet. Ideal for content distribution from hub to affiliates who wish to carry your content. Works well to correct packet loss and jitter across wireless IP links. Cost effective alternative to satellite content delivery. Ideal technology for CDN Operators or mobile network operators who are deploying any kind of traffic across long distances. Sold in pairs or point-to-multipoint. Works with DOZER Link™ encoders and decoders. Also available in 1 RU and software license versions.

  • Analyzes HTTP Live Streams (HLS) – works with both VOD and live content
  • Analyzes TS segments of the stream and provides useful information about:
    • Stream information: Type of stream (live or VOD), media sequence, type of encryption, and number of segments
    • Tracks information about video and audio tracks – profiles, codecs, resolution, sample rate, channels, etc.
    • Timing Information: Checks if bitrates and segments are properly aligned
    • Frames Information: Keyframe interval, frames sequence.  Useful to check if every segment starts with a keyframe.  Ensures smooth bitrate switching.
  • Near-real-time display of key indicators, and trends
  • Drill down display of other "vital signs"
  • Historical reporting
  • Supports all types of IP stream inputs
  • Over 20 Monitored Events and Properties

AI Features

  • AI Assisted Monitoring Rules:
    • Automatic learning of adequate ETR 290 alarm thresholds
    • Automatic detection and reporting of Source Network bandwidth starvation patters and auto adjustments of alarms based on this learning (peak time usage reports)
    • Automatic detection and reporting of imminent hardware failure (MTBF reports), i.e., proactive smart alarms to look at a group of channels that change their average pattern of failures


  • Completely corrects packet loss and jitter in transmission path
  • Available with Failover Option
