ABSTRACT:
A method and circuit for generating an adaptive constant of an adaptive modulator for the band compression of video signals. If a maximum amplitude value detected from picture elements in a block is greater than a first reference value, the number of picture elements having a lower amplitude value than a second reference value in the block is calculated. If the calculated number of picture elements is greater than a given number, the maximum amplitude value is divided by a given constant and an adaptive constant corresponding to the divided value is generated from an adaptive constant memory.
