5 is a diagram showing a display screen displayed by the program guide display device of FIG. The operation of the program guide display device of the fourth embodiment is shown in FIG.
Steps S1 to S7 are the same as those of the program guide display device according to the second embodiment, and a description thereof will be omitted.

At step S8, the display data of the program guide additional information formed on the work RAM 3 is stored in the VRAM 4
If the message does not fit in the message window area, a scroll instruction is issued from the window control circuit 8 to the scroll control circuit 11. The scroll instruction may be given by the user selecting the arrow 48 displayed on the display screen.

Upon receiving the scroll instruction, the scroll control circuit 11 causes the image displayed on the message window 24 to be scrolled. For this purpose, the scroll control circuit 11 controls the transfer source address when the display data of the program additional information configured on the work RAM 3 is taken into the window control circuit 8.

For example, the scroll control circuit 11 scrolls upward by increasing the source transfer start address by several horizontal periods every several vertical periods, and reduces the source transfer start address by several horizontal periods every vertical period. Scroll down by doing. Further, the scroll control circuit 11 scrolls to the left by increasing the transfer source address in line units by several pixels every several vertical periods, and reduces the transfer source address in line units by several pixels every several vertical periods. To scroll right.

Thus, when the program additional information is displayed in the message window 24, the characters are enlarged,
Since the scroll control circuit 11 can display a large character without switching the screen, the operability can be improved without impairing the operability.

The scroll control circuit 11 repeats increasing the transfer source transfer start address by a length corresponding to the vertical length of the message window 24 every predetermined period, for example, every several vertical periods, thereby repeating all display data. It may be displayed in the message window 24.

The scroll control circuit 11 controls the image of the program guide windows 22 and 32 and the enlarged window 23 in the same manner as the scroll of the image of the message window 24.
May be configured to scroll the image.
