description This invention relates to a method for controlling the integral code rate of low complexity, which first of all, distributes ralated bit number of each frame in the GOP, then distributes bit numbers for the current frames in the GOP then evaluates the quantized parameters of a macroblock needed by coding based on the integral code rate control technology, then feeds back the quantized parameters to the rate distortion optimizing technology and other code parts, in which, many models are used including a complexity evaluation model, a liquid flow barrage model and a integral code rate control model.
