Abstract

See full text

A method and apparatus for eliminating flicker by quantizing values based on previous quantization is described. In one embodiment, the method comprises encoding a first coefficient value in a first frame of a motion sequence and subsequently setting a second coefficient in a second frame of the motion sequence and in the same position as the first coefficient to be within a predetermined closeness with the value of the first coefficient.
