Abstract
A video coding device capable of adaptively processing input video data according to property of the data and realizing effective progressive transmission of the coded data even if image components are different in size and/or different in the number of subbands. The above-mentioned object can be realized by the provision of a transferring-order deciding and ranging portion that can prepare an integrated component unit by forming combinations of subband-based frequency-coefficients of respective components Y, U and V and can change the number of respective elements of respective components Y, U and V.
