Abstract
The invention relates to a method for encoding a plurality of non overlapping blocks in a picture. The method comprises the steps of: transforming each of the blocks into a transformed block of coefficients in the frequency domain by applying a predefined transform; scanning the coefficients of at least two neighboring transformed blocks jointly from the lowest frequency to the highest frequency according to a predefined scanning pattern, the group of at least two neighboring transformed blocks being called super-block; and entropy coding the scanned coefficients of the super-block into an entropy coded group of bits.
