Abstract
A method of adding comfort noise to a video sequence comprising setting parameters of a deblocking filter of a video encoder to change values during the video sequence, encoding frames of the video sequence using the parameters of the deblocking filter that are set to change values during the video sequence, thereby introducing comfort noise in the video sequence, and including the encoded frames in a bitstream together with an indication of which parameters of the deblocking filter were used when encoding the frames of the video sequence.
