Abstract: For transmission of coded picture data, coded data may be arranged in blocks having a predetermined average length. Blocks which are not full are filled with data from other blocks. To support decoding in the presence of interference, each of the blocks additionally contains an address pointer which points to addresses in a decoder memory from which data separated from blocks having a greater than the average word length are reconstituted and used for decoding. The additional address pointer information, for a constant channel capacity, results in a lower data rate for picture data, which may lead to reduced picture quality during undisturbed decoding. Respective recovery pointer pairs having full word width are inserted between a predetermined number of data blocks, whereby other address pointers only cover the Least Significant Bits having full word width. Accordingly, additional data can be inserted into the data stream.
