In one embodiment, a system includes a compositor operable to receive a plurality of source video streams, each containing source images, and to convert each of the source video streams into source slice groups using flexible macroblock ordering. An analog dither signal andor a digital dither signal is provided for modulating the AD converter input signal andor DA converter input signal, respectively, separately, or in combination, to enhance dynamic range accuracy of the resultant analog information output signal representative of the quantity of the parameter intended to be sensed. The received distorted signal is processed, and an image is formed, and then displayed, from one of the higher order component signals of the received distorted signal.
