DEVICE AND METHOD FOR DISPLAYING VIDEO PROVIDED WITH CHARACTER DISPLAY FUNCTION

摘要

PROBLEM TO BE SOLVED: To make compressible a font table and also largely reducible the memory capacity for the font table when displaying an arbitrary character in a prescribed character display area. SOLUTION: This video display device is provided with a ROM 11 in which a font table T1 compressed in row unit and a command table T2 for restoring the compressed font table T1 are stored, and a CPU 13 for restoring the original font table T1 in row unit based on the command table T2 stored in the ROM 11. This configuration makes it possible to compress the font table T1 so as to delete data blank parts not displaying the characters, and data string in the blank parts.
