Scope
The present document provides a framework for end-to-end quality measurement of multimedia services. The framework defines measurement options for performing pre-transmission quality assurance@ in-service network quality measurement@ and for client-device quality monitoring at different points in the transmission chain. The document is defined for services delivered on an IP network and is concerned solely with non-interactive services (e.g. IPTV@ video streaming). The present document is intended to provide industry and metric developers with a framework for implementing the appropriate quality metric at each point in the transmission chain. Recommendations are provided on the type and purpose of metric(s) for use at the head-end@ network and end device (e.g. STB). Wherever possible@ existing standardised metrics and measurement methods being appropriate for use in measurement tools in the transmission chain belonging to the defined framework are identified.
