In your example photo, you are feeding analog video from SNES to scaler, then analog video from scaler to display driver, then digital RGB from display driver to display. TV5725 can drive up to 24-bit RGB display directly, so this setup can possibly be simplified. Are you interested in creating a board with this chip and parallel RGB interface? It can possibly be used to connect DVI-D encoder or used as input.
