Abstract

본 발명은 피디피 티브이(PDP TV)의 메모리 장치에 관한 것으로, 방송국으로부터 전송되는 복합영상신호가 A/D변환부를 통해 디지털의 영상데이터로 변환되고, 데이터 처리부를 통해 동일한 가중치를 갖는 영상데이터로 재배열된 다음, 기수필드의 영상데이터는 기수필드 메모리에 저장되고, 우수필드의 영상데이터는 우수필드 메모리에 저장된 다음, 메모리 제어부로부터의 선택을 위한 제어신호에 의거하여 기수필드 메모리와 우수필드 메모리에 저장되어 있는 각 필드의 영상데이터가 번갈아가며 PDP 구동회로로 제공되므로써, 비월주사 방식으로 영상데이터를 처리하므로, 순차주사 방식으로 변환하기 위해 구비되는 메모리의 용량을 절감시킬 수 있도록 한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a memory device of a PDP TV, wherein a composite video signal transmitted from a broadcasting station is converted into digital video data through an A / D converter, and reconverted into video data having the same weight through a data processor. After arranging, the image data of the odd field is stored in the odd field memory, the image data of the even field is stored in the even field memory, and then stored in the odd field memory and the even field memory based on a control signal for selection from the memory control unit. Since the image data of each stored field is alternately provided to the PDP driving circuit, the image data is processed in the interlaced scanning method, thereby reducing the capacity of the memory provided for converting the progressive scanning method.
