A computer readable medium having instructions is provided. In one embodiment, the method includes receiving a branch instruction and storing local branch prediction information for the branch instruction including a local predictability value for the local branch prediction information. The method may further include displaying various temperature warning by multiple temperature indicators if the surface temperature is above or below the threshold temperatures. The combined digital signals are then provided to a receiver that includes a converter for returning the digital RF signals to analog RF signals and then providing the analog signals to a headend for further processing. The luminance correction coefficient determination unit corrects the provisional luminance correction coefficient using the improper coloring degree.
