A video signal processing system for processing a video data Vand graphic data Dincludes a filter unit, which receives the video data V. The filter unit filters the video data Vto convert the video data Vinto video pictures formatted with a different number of columns and/or lines, and provides a filtered video signal indicative thereof. The filter unit buffers individual pixels and/or lines in a first memory device. A second memory device receives and stores the graphic data Dand the filtered video signal and provides stored signals indicative thereof. A third memory device is connected to the second memory, and stores data received from the second memory device. A mixing unit receives and mixes the stored graphic data and the stored filtered video data to provide a video output signal V.
