What is IPTV? IPTV is: TV Services over managed NGN IP network Broadcast, On-demand and Interactive TV Personalized content Cheaper to scale, unlimited number of channels A consumer technology for the delivery of broadcast TV , on- demand video and interactive entertainment services to consumer TV sets over IP networks

IPTV is:

TV Services over managed NGN IP network

Service-Centric PM Approach The mapping between network and service levels forms an significant part of the SLA negotiation Service level metric categories include availability, reliability, usability, efficiency, accuracy & security

The mapping between network and service levels forms an significant part of the SLA negotiation

Service level metric categories include availability, reliability, usability, efficiency, accuracy & security

QoE: The Ultimate Metric of Performance The level of service quality as perceived by an end-user is called Quality of Experience (QoE) Often referred as Mean Opinion Score (MOS) Emotional aspects Final ball in final game in MLB playoffs QoE models (MPQM, R-factor, PSNR) differ in formulas combining different video and transport parameters Probe vendors enhance QoE solutions by providing availability, channel zapping and security measurements PSNR vs Packet Loss

Web Reporting Service Modeling Data Collection & Processing KPI & KQI Generation Degraded Service Quality Events Service Impact Analysis Fault Management Reporting Automated Impairment Resolution Report generation on ad-hoc and scheduled basis

Degraded Service Quality (DSQ) Events Transient quality impairments – quality level degradations which pass over time (e.g. MOS less than X for more than N seconds) Threshold levels Low threshold When crossed, operators should address the impairment before customers are affected. High threshold When crossed, customers’ experience is impacted and the degradation is noticeable. Abatement Threshold (Hysteresis) Low threshold High threshold 55% 50% 70% Onset Abatement

Transient quality impairments – quality level degradations which pass over time (e.g. MOS less than X for more than N seconds)

Threshold levels

Low threshold

When crossed, operators should address the impairment before customers are affected.

High threshold

When crossed, customers’ experience is impacted and the degradation is noticeable.
