1. A method for modifying bits of an input pixel data word, comprising: outputting an embedded data packet using an embedded data engine; receiving the input pixel data word and the embedded data packet at decatenation circuitry; separating the input pixel data word into a first fragment of the data word and a second fragment of the data word at the decatenation circuitry; and producing an output data word comprising the embedded data packet and a modified version of the first fragment of the data word using concatenation circuitry.
