Abstract
A television viewer uses a PIP format for display of program related information such as television program listings from a program schedule data base in the background and moving, real time images of a program selected from the displayed listings in the PIP window. All the text of the background information lies outside the PIP window. In one embodiment, as the viewer selects a particular program from the display of current television program listings by means of a cursor or a code number, the corresponding program automatically appears in the PIP window.
