The circuit for generating the multiwindow signal to a monitor with picutre-in-picture function includes a horizontal counter (10) for generating the 1st-4th horizontal counting signals sequentially, a vertical counter (20) for generating the 1st-4th vertical counting signals sequentially, a horizontal position signal generator (30) for generating the horizontal counting signals corresponding to the horizontal position of the equivalent bank region, a vertical position signal generator (40) for generating the vertical counting signals corresponding to the vertical position of the equivalent bank region, and the window signal generator (50) for generating the horizontal and vertical window signals and logically combining them to generator the window signals selecting multiple bank regions. |
