Tektronix has added significant new reporting capabilities to its Sentry digital content monitor for cable television operators.

The new Sentry application is said to improve the quality of operators’ video services by quickly identifying, diagnosing and repairing video and audio errors that can degrade viewers’ quality of experience (QoE).

The first new reporting capability integrates Sentry’s ground-breaking Video and Audio QoE Scoring System – the industry’s first system to gauge the actual severity of video and audio impairments for subscribers – with the SCTE 168-6 ‘Recommended Practice for Monitoring Multimedia Distribution Quality,’ a popular method for reporting program availability.

Integrating SCTE 168-6 support with Sentry’s capability for detecting video and audio errors that are not always caused by dropped packets (e.g., video freeze, black screen, tiling, macroblocking, compression artifacts, loss of audio channel or audio quality issues) enables video service providers to take advantage of a popular reporting methodology coupled with the ability to identify the widest range of QoE-impacting events.
