Abstract: The present disclosure provides an improved decoding method to ensure consistent quality of decoded images. The method for decoding for picture or video processing from a bitstream, comprises: obtaining, from the bitstream, a rate control parameter indicating a compression ratio and obtaining an asymmetric interval defined by an upper and lower rate control threshold, and determining whether a value of the rate control parameter lies outside of a range of the asymmetric interval. If the value of the rate control parameter lies outside of the range of the asymmetric interval, the method further comprises clipping the rate control parameter to obtain a clipped rate control parameter. An asymmetry of the asymmetric interval is characterised in that a first magnitude defined by a difference between a largest representable value of the rate control parameter and the upper rate control threshold is greater than a second magnitude defined by a difference between a smallest representable value of the rate control parameter and the lower rate control threshold.
