PROBLEM TO BE SOLVED: To provide a method of storing data in a memory and extracting the data from the memory and a graphics controller for implementing the method. SOLUTION: The graphics controller for preparing data to be displayed on a display device by interlacing scanning is provided. The graphics controller is provided with the memory, a line buffer suited to the reception of video data and a data array circuit for communicating with the line buffer. The data array circuit processes received data in order to store received video data in the memory as odd segments corresponding to even segments so that the even segments are associated with data from even field lines, the odd segments are associated with data from odd field lines and the data of one pixel are defined by a pair of an even segment and an odd segment. One pipe buffer for retrieving an even segment and its corresponding odd segment by one memory access to the memory is also included in the graphics controller. COPYRIGHT: (C)2004,JPO
