1. A method to reduce coding artifacts within a discrete decoded picture, said method comprising the steps of:

  • spatial and/or temporal filtering with respective filter characteristics dependent on an image quality value;

    wherein said image quality value is determined based on a user selection and wherein the temporal filter operation decreases with an increasing image quality value; and

    wherein the temporal filter operation is realized with a blending filter applied to an entire frame which determines a new frame as a weighted sum of a predicted frame and an actual frame, which weighting is dependent on said image quality value and a difference of the actual frame with the predicted frame.
