A method, a device, and a non-transitory computer readable medium for performing dithering on an L bit long input data are presented. An M bit long random data is generated, wherein M is a number of least significant bits of the input data. An M bit long frame counter value is added to the random data. The input data is rounded up to L-M most significant bits when the M least significant bits of the input data is greater than the sum of the frame counter value and the random data. The input data is truncated to the L-M most significant bits when the M least significant bits of the input data is less than or equal to the sum of the frame counter value and the random data.
