The present invention relates to a conventional one JPEG2000 of yet less hardware size compared to the structure to handle the lifting discrete wavelet transform in real time of the lifting discrete wavelet transform unit, the lifting discrete wave with respect to the input video signal scarlet horizontal module to perform the filtering for the row direction of the first level of conversion; And it provided with a vertical module to perform the filtering for both the second level over the row direction and the column direction, as well as filters for the column direction of the first level with respect to the signal from the horizontal modules. ; Lifting discrete wavelet transform, in real time, the horizontal filter, a vertical filter, the processing unit
