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.	MPEG Generator
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 measurements which help to detect such problems before viewers lose their service and picture completely.	RF and MPEG
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.	MPEG Software
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.	MPEG Generator
Video Over IP Cross Layer Measurements Explore some of the challenges around delivering superior Quality of Service (QoS) in the design, rollout and management of Video over IP Networks.
