The present invention provides a method of interactive gaming applied to an interactive case and a tablet, wherein the interactive case is arranged to be attached on the tablet, and the interactive case includes a transmission port arranged to communicate with the tablet and a plurality of notches. The flat panel illuminator provides backlighting for scanning transparencies, such that light passes through the transparency only once and into the scanner optics within the scanner base. In the luma predictor, luma pixel values of the predicted signal are computed based only on luma pixel values of the base layer, while in the chroma predictor, chroma pixel values of the predicted signal are computed based on both the luma and the chroma pixel values of the base layer.
