Abstract
A television screen (24) is displayed as a window (25) within a larger displayed image (21), also referred to as a “picture-in-picture.” A control program associated with the window (25) provides additional functions to the window, including the ability to view the time, title, and other information about future programs, in the window (25). A user can switch between various preset lists of channels, and can dynamically edit such lists to add or delete channels. The control program senses the location of a cursor (37) relative to the window (25) and a control region, as defined therein. Depending upon the location of the cursor (37), the window (25) is either in a reduced-size state with fewer controls visible, or in an expanded-size state with greater controls visible.
