scope:

The scope of the framework is to set out a common conceptual framework and definitions that can be applied to all network types, service types, and service instances as defined in other IIF documents.

IPTV services are defined in ATIS-0800002 as follows:

IPTV is defined as a managed service providing the secure and reliable delivery to customers of entertainment video and related services.

This document specifies the general QoS framework upon which the definition of quality metrics and measurement methods are based. This is accomplished by use of a Measurement Model and a multi-layer measurement concept describing the IPTV service delivery framework from a logical perspective. This document identifies reference points and defines metric concepts that may be used to measure the quality of the video applications and other aspects of service delivery.

The framework document also recognizes that multiple service providers may be involved in the service delivery and interprovider or interdomain in QoS measurement will be considered within the scope. The model used for this working text applies to the end-to-end IPTV service and network delivery chain including content provider, service provider, network provider, and customer domains. The four communicating domains as described in the ATIS 0800002, IPTV Architecture Requirements, are shown in the following figure:

Specific measurement points may be specified within and at the boundary of each of these domains. Metrics may also describe the performance of any layer of the protocol stack that affect the end-toend video application performance.

Purpose

The Framework document provides concepts, models, and definitions that are used as the foundation content for further definitions and descriptions of IPTV QoS/QoE metrics, models, tools, and techniques for measurements of QoS/QoE for IPTV services.

The Framework document also relies on models, definitions, and service descriptions documented in the ATIS-0800002, IIF Architecture Requirements document, and ATIS-0800001, IIF Digital Rights Management (DRM) Requirements document.
