Summary: | An apparatus and method for video coding is disclosed wherein one frame is divided into a plurality of blocks. The present invention divides an input frame into a plurality of blocks and transforming the blocks to a frequency domain; rearranges the transformed frequency band-based coefficients in the order of priority based on a degree how much information required for image reproduction is included; and coding the information concerning the position and amplitude of the rearranged coefficients in the order of priority based upon significance and outputting the bit streams arranged according to the significance. |
