 The CTIA/GTIA receives Playfield graphics information from ANTIC and applies colors to the pixels from a 128 or 256 color palette depending on the color interpretation mode in effect.CTIA/GTIA also controls Player/Missile Graphics (aka sprites) functionality including collision detection between displayed objects (Players, Missiles, and ANTIC's Playfield), display priority control over objects, and color/luminance control of all displayed objects.CTIA/GTIA outputs separate digital luminance and chroma signals, which are mixed to form an analog composite video signal.
