Zusammenfassung:PURPOSE: To remove the effect of a stagger-like pixel array. CONSTITUTION: A graphic data unit 17 for a digital television receiver 10 using a space optical modulator 16 has a graphic processor which off-loads a graphic processing task for closed caption and on-screen display from a main processor 14, for example. The graphic data unit 17 has a character memory storing fonts for closed caption and an on-screen display character. A read-only memory stores a graphic primitive and the character font and the graphic primitive compensate the layout of the stagger-like pixel of the space optical modulator 16.
