1. A system for dithering video data, wherein the system is operable in at least one mode in which it applies at least a first kernel sequence and a second kernel sequence to each set of a sequence of sets of input video bits, repeats application of the first kernel sequence after a first number of the sets have been dithered in response to said first kernel sequence, and repeats application of the second kernel sequence after a second number of the sets have been dithered in response to said second kernel sequence, wherein each said kernel sequence is a sequence of kernels consisting of dither bits.
