Abstract: A method includes, in an encoder, dividing an image into blocks, and producing respective compressed descriptions of the blocks. First data, which contains at least some of the compressed descriptions, is generated such that a compressed description of each block within the first data is accessible irrespective of the compressed descriptions of the other blocks. Second data, which contains at least a portion of the compressed descriptions or of the blocks and has a better error resilience than the first data, is also generated. The first and second data are stored in a memory. At a decoder, the first and second data are read from the memory, and the image is reconstructed from the read first and second data.
