Telecom Italia Media Broadcasting (TIMB), Italy’s third largest digital television broadcaster, is using the Tektronix Sentry digital content monitor to ensure picture and sound quality. ??TIMB has deployed Sentry in its central headend and several other key locations in its network to monitor all of its high definition (HD) and standard definition (SD) programming to identify video and audio errors that can impact viewers’ quality of experience (QoE).

At its central headend facility in Rome where TIMB aggregates its programming content, Sentry is used to detect errors after the programming has been encoded and then again after it has been multiplexed – two critical steps where errors are likely to occur.

Sentry utilizes advanced deep packet inspection technology to give video service providers unparalleled visibility into network anomalies at the IP and MPEG layers at all critical locations in the network. This enables the quick identification, diagnosis and repair of video and audio errors regardless of where they occur in the network; from ingest at the headend through the network edge just before it is delivered to the home.
