摘要：
A method and apparatus for selecting a quantizer scale for each macroblock within a frame to optimize the coding rate is presented (130). A quantizer scale is selected for each macroblock (120) within each frame such that the target bit rate for the frame is achieved while maintaining a uniform visual quality over the entire frame.
