Embodiments of the invention enable the efficient use of shared resources by different processes, such as background and foreground processes sharing a mass storage device. The remote controller includes a provision for enabling a manual entry of a channel selection preference or other user determined command. The peripheral edge along the four sides of the electro-optical panel is bonded to the upper frame by an adhesion element, and at least two corners of the intermediate frame are exposed in the open portions of the upper frame.
