Abstract

A simply-constructed data processing system for a karaoke machine can process data to display a plurality of languages. A data processing apparatus processes data composed of one-byte or two-byte character codes, each representing a character. A display can display characters represented by the character codes. A set of font memory can store the character font of each of the character codes for supplying font data. The font memory is divided into four regions, the first to the fourth, according to the combinations of the first two bits of a character code. Japanese characters can be assigned to the first region as the first character group of the first language based on a shift JIS standard, and Hankul characters can be assigned to the fourth region as the second character group of the second language. An identifying apparatus identifies one of the regions to which a character code corresponds, according to the first two bits of a character code.
