Zusammenfassung:Disclosed herein is a method for predicting the quality Q of a video bit stream. The method comprises obtaining a video segment and a corresponding bit stream, parsing the bit stream by a bit stream parser, and obtaining bit stream parameters. The quality Q is predicted by using a deterministic model and a machine learning model with the obtained bit stream parameters, wherein the predicted video quality is a weighted sum of the prediction of both models. A residuum of the deterministic model is predicted by the machine learning model.
