Cable TV Operators

Tektronix Video test products help cable operators in these areas:

  • Headend monitoring at a range of network access points like ingest, transport and access
  • Detection and recovery of major subscriber impacting events (QoE errors) including video freeze/black, tiling, audio silence ad audio level issues
  • Network Troubleshooting & Diagnostics

Secondary or Regional Headend Monitoring

Product Description
Sentry Acquisition: Sentry's "Deep Dive" monitoring enables video service providers to detect Video & Audio level impairments in the incoming feeds (e.g. the SPTS from the satellite receivers). This includes perceptual video and audio QoE scoring (tiling, audio disruptions and audio level issues, etc.), black/frozen screen and audio silence.
Sentry Verify Ingress Monitoring: Sentry Verify enables video service providers to detect transport, video and audio errors on the incoming feeds at each of the regional headends.
Sentry Edge RF Monitoring: Sentry Edge enables video service providers to detect RF, Transport, Video and Audio errors on the output of the QAM modulators.
