摘要： Film grain simulation within a receiver occurs by first obtaining at least one block of pre-computed transformed coefficients. The block of pre-computed transformed coefficients undergoes filtering responsive to a frequency range that characterizes a desired pattern of the film grain. In practice, the frequency range lies within a set of cut frequencies fHL, fVL, fHH and fVH of a filter in two dimensions that characterizes a desired film grain pattern. Thereafter, the filtered set of coefficients undergoes an inverse transform to yield the film grain pattern.
