Central or Master 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.
Medius and
Consul		 For centralized management, reporting, alerting, aggregation and configuration of monitoring devices from the source to the edge of the network.

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.

Measuring Video and Audio Quality of Experience (QoE)

This application note shows you how to objectively rate a program at different points in the network to understand and pinpoint when and where degradation has occurred.

Critical RF Measurements in Cable, Satellite and Terrestrial DTV Systems

The secret to maintaining reliable and high-quality services over different digital television transmission systems is to focus on critical factors that may compromise the integrity of the system. This application note describes those critical RF test measurements which help to detect such problems before viewers lose their service and picture completely.

Solving Intermittent Transport Stream Problems with CaptureVu Technology

CaptureVu technology allows you to set an error break point on an incoming real time or stored MPEG transport stream. By setting specific conditions for CaptureVu technology you allow the analyzer to find intermittent problems for you, trigger a recording to memory, or stop analysis to allow you to drill down to the route cause of an issue quickly and efficiently.

Video and Audio Quality Assurance For Next-generation Video Networks

A Guide to Automating Quality Control in File-based Workflows

A Guide to MPEG Fundamentals and Protocol Analysis

MPEG is one of the most popular audio/video compression techniques because it is not just a single standard. Instead, it is a range of standards suitable for different applications but based on similar principles. MPEG is an acronym for the Moving Picture Experts Group.

Troubleshooting Quality of Service (QoS) and Quality of Experience (QoE) issues in Video Service Provider Networks

Learn the benefits and faults of the two most common test methods for troubleshooting video signal problems and the critical capabilities needed in an MPEG analyzer.

QoE: What it Means to Subscribers and Service Providers Webinar

Quality of Experience has emerged as the key focal point for cable operators. This webinar explores the results of a recent video network monitoring market study that points to the growing need for network monitoring. Learn about Recommended Best Practices for QoE monitoring, as well as strategic decisions related to Video Monitoring Deployments from Time Warner Cable.

MPEG Timing and Synchronization Webinar

Whether your job is to design Encoders and Set Top Boxes (STBs), or to evaluate or integrate them, dealing effectively with timing concerns is essential. A Tektronix Buffer Analyzer can pinpoint the source of timing problems, and our webinar covering Program Clock Reference (PCR) issues and more explains timing principles and their impact on video quality.

Basic MPEG Overview / MPEG Made Easy Webinar
