ABSTRACT:
An image decoding method, apparatus and program for decoding coded picture data is disclosed. In the method, apparatus and program, the coded picture data is entropy-decoded to derive four transform coefficient strings each comprising entropy-decoded sixteen (16) transform coefficients. The four transform coefficient strings are combined into an 8x8 block of entropy-decoded sixty four (64) transform coefficients by de-interleaving the four strings in such a manner as to select a lower frequency transform coefficient alternately from the four strings and arrange it in the 8x8 block in an order of a low frequency to a high frequency. An inverse orthogonal transform is then performed on the 8x8 block of the entropy-decoded sixty four (64) transform coefficients.
