Abstract:
1. An encoding method for encoding a representation of an image, the method comprising: creating, in an encoder, a residual block from an original block and a prediction block which is an approximation of the original block, wherein the created residual block comprises residual block elements; re-ordering, in the encoder, the residual block elements within the residual block; applying, in the encoder, a transform to the re-ordered residual block; and generating a signal, indicative of the performed re-ordering, to be conveyed to a decoder; selecting one re-ordering to be available to a set of consecutive residual blocks; and including, in the generated signal, an indication of the selected re-ordering pointing to the set of consecutive residual blocks, wherein the indication of the selected re-ordering pointing to the set of consecutive residual blocks is signaled in the generated signal once per the set of consecutive residual blocks.
