<p>PURPOSE:To obtain a synthesis moving picture by storing a video signal corresponding to each picture into each frame memory, storing Y, R-Y to a 1st field memory and Y, B-Y into a 2nd field memory and reading them in the unit of fields. CONSTITUTION:Y, R-Y and Y, B-Y of input picture data VD1-VD4 are written in line memories 10A-10D for one horizontal line each by using a prescribed write clock for each horizontal period according to a prescribed format. Moreover, the Y, R-Y or Y, B-Y for one horizontal line are read from the line memories 10A-10D by using a prescribed read clock and written in frame memories 12A-12D. Each frame memory is formed to be 2-layer structure consisting of the 1st field memory M0 for the Y, R-Y and the 2nd field memory M1 for the Y, B-Y. Then the data for 2 lines are outputted to a conventional receiver from both the memories via output terminals 70, 72, 74 while arranging the time to synthesize 4 moving pictures into one picture.</p> |
