Framework and standardization of quality of experience (QoE) design and management for audiovisual communication services

Abstract

The quality of rich broadband services that use audio and visual media such as Internet protocol television (IPTV) and video telephony, which are expected to become more widespread over the Next Generation Network (NGN), should be evaluated subjectively by users. This is referred to as quality of experience (QoE). This article introduces the technical framework of QoE evaluation methodologies for quality design and management of audiovisual communication systems. It also describes the latest status of international standardization activities for these technologies.
