Abstract
A method of generating a sequence of display frames for display on a display device, wherein the sequence of display frames are derived from a data string which is encoded to include error correction in order to enable recreation of the data string at a receiving device, includes dividing the data string to be encoded into a plurality of source segments; encoding the plurality of source segments to generate a plurality of codewords, each codeword comprising a plurality of codeword bits; and positioning codeword bits in the sequence of frames.
