Measuring ATM video quality of service using an objective picture quality model

End-to-end quality of service for real-time video delivery over ATM networks depends on both video coding and network performance. Historical measures of QoS for data services have involved packet delivery parameters such as cell loss and delay, but these are not directly representative of a user's perception of the delivered video quality. To this end, this paper describes the use of a video quality measurement scheme that employs a human vision based picture quality model to objectively estimate end-user video quality. We present results to demonstrate that the video quality analysis based approach can be used to determine performance characteristics for distribution-quality video coding parameters over ATM networks.
