Tektronix quality assurance for Cogeco
November 17, 2011
Tektronix, a specialist in broadcast video test, monitoring and analysis solutions, has announced that company’s flagship Sentry digital content monitor has been selected by Cogeco Cable, Canada’s fourth largest cable operator, to help ensure their video services are delivered with exceptional quality.
Cogeco Cable will deploy Sentry’s advanced Quality of Experience (QoE) and Perceptive Video Quality (PVQ) modules. With QoE, Sentry does a full decode of each MPEG packet looking for structural errors that cause picture and audio impairments. Each impairment is scored based on the severity, taking into account the frequency, duration and position on viewers’ screens of each impairment. In addition to QoE, Sentry’s PVQ module detects picture blockiness and other artifacts caused by over-compression using an eMOS (effective Mean Opinion Score) based scoring algorithm. Sentry’s combination of advanced QoE capabilities and PVQ provides Cogeco Cable with the most comprehensive real-time monitoring and alerting system available today.
