After wavelet transform and quantification, a prediction module is introduced to estimate the entropy of EBCOT code block within available bit plane, then using the summation estimate entropy of each code block to allocate the rate for each code block. T2 encoder sends feedback to control the coding depth by the pre-allocation bit rate and complete the rate-distortion optimization truncation.
