    Abstract: A display control apparatus is provided including a detection unit for detecting contact of an operation tool with a display surface of the display unit, a contact determination unit for determining contact state of the operation tool with the display surface based on a detection result, a contact mark display processing unit for displaying on the display unit a contact mark indicating a form of a contact area of the operation tool when the operation tool is determined to be in contact with the display surface, and a screen display processing unit for causing an object, the contact mark, and the pointer displayed in a predetermined display area to be displayed near the contact area of the operation tool when a predetermined state to start a change of display of the display unit is detected in the state in which the operation tool is in contact with the display surface.

    Abstract: The invention provides an electrical program guide system and method by which a desired program can be selected rapidly with certainty, intuitively and directly from among a large number of programs. For example, nine reduced screens reduced from nine screens of different programs are arranged in a 3x3 matrix to construct one multi-screen as a screen for program selection. Six such screens for program selection are individually produced by multi-screen production circuits and encoded by MPEG video encoders, and then multiplexed by a multiplexer so that they may be transmitted via a single transmission channel. The multiplexed signal is subjected to error correction coding and QPSK modulation by a transmission line coding apparatus and then it is further subjected to frequency conversion by an up converter. The resultant signal is transmitted to an artificial satellite through a mixer and a parabola antenna. Each multi-screen received on the reception side from the satellite is displayed as 3x3 pieces of reduced screens of full motion, and a viewer will find out and directly select a desired program from a preview screen formed from the reduced screens.
