As multimedia IP services become more popular, commercial service providers are under pressure to maximise their utilisation of network resources whilst still providing a satisfactory service to the end users. The present work examines user opinions of quality and acceptability for video streaming material under different network performance conditions. Subjects provided quality and acceptability opinions for typical multimedia material presented under different network conditions. The subjective test showed that increasing loss levels results in poorer user opinions of both quality and acceptability. Critically, for a given percentage packet loss, the test found that increasing the packet burst size produced improved opinions of quality and acceptability. These results suggest that user-perceived Quality of Service can be improved under network congestion conditions by configuring the packet loss characteristics. Larger bursts of packet loss occurring infrequently may be preferable to more frequent smaller-sized bursts.
