PROBLEM TO BE SOLVED: To provide a method for generating predictive macro blocks in hierarchical encoding. SOLUTION: An image data macro block (MB<SB>EL</SB>) belongs to an enhancement layer and an image data block (B<SB>BL</SB>) in a base layer corresponds to the image data macro block (MB<SB>EL</SB>). With respect to the image data macro block (MB<SB>EL</SB>), a predictive macro block (MB<SB>pred</SB>) of image data is generated from the image data block in the base layer, which has been beforehand encoded and reconstructed, and a residue macro block (MB<SB>EL</SB><SP>residues</SP>) is generated from the predictive macro block (MB<SB>pred</SB>) and the image data macro block (MB<SB>EL</SB>) in the enhancement layer. The image data block in the base layer is different from the corresponding block (B<SB>BL</SB>). COPYRIGHT: (C)2008,JPO&INPIT |
