Abstract
There is currently much discussion of Quality of Service (QoS) measurements at the network level of real-time multimedia services, but it is the subjective quality perceived by the user that will determine whether these applications are adopted. This paper argues that ITU-recommended methods for subjective quality assessment of speech and video are not suitable for assessing the quality of many newer services and applications. We present an outline of what we believe to be a more suitable testing methodology, which acknowledges the multi-dimensional nature of perceived audio and video quality. 1.1 Keywords Speech quality, video quality, subjective measurement. 2. INTRODUCTION The number of real-time multimedia applications over packet networks has been increasing steadily, and with it the need to measure and assess the quality of multimedia delivered in this manner. There has been a surge in literature addressing Quality of Service (QoS) issues, but the emphasis has been on the qua...
