Abstract: A processing unit (PU) is configured to generate reference values based on previously displayed frames in order to decode encoded frames having one or more noise-based effects. To this end, the PU includes a noise effect circuitry configured to determine noise values associated with a previously displayed frame. The noise effect circuitry then subtracts respective noise values from the pixel values of the previously displayed frame to determine reference values for decoding an encoded frame. Further, the PU includes a decoder that decodes the encoded frame based on the determined reference values.
