A real-time MPEG-4 video transmission system is used to conduct subjective video quality measurements. In the measurements, three video QoS (Quality of Service) parameters, that is, the frame size, frame rate, and quantization scale change, then the double stimulus continuous quality scale method is used to obtain the subjective test scores from the subjects. This report provides the experimental results and discusses on the correlation between the QoS parameters and the user assessment, which might be useful for user-adaptive QoS control in video streaming service.
