摘要： A method and a device utilizing an algorithm using measurement data derived from parameters related to a video-streaming player and/or parameters related to data transport is disclosed. The data are used as input data in a model designed to generate a value corresponding to the quality of the multimedia sequence, such as for example a MOS score.
