摘要： 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.

摘要： The present invention is directed to a decoder for decoding encoded video data which comprises blocks of transform coefficients. The decoder comprises a reconstruction information receiver which acquires reconstruction information from an encoder regarding reconstruction of the blocks of transform coefficients. The decoder also comprises an entropy decoder which decodes the blocks of transform coefficients into decoded blocks of transform coefficients. The decoder further comprises a coefficient list maker. According to the acquired reconstruction information, the coefficient list maker combines the transform coefficients of the decoded blocks into a first list of transform coefficients in which the transform coefficients of a respective decoded block are interleaved with the transform coefficients of another decoded block.
