An overlay manager (OVR) is responsible for composting selected input layers together to generate the final display output frame. DISPC implements two identical overlay managers (see DISPC Architecture Overview):
Each OVR is preceded by a programmable input pipeline selector which re-maps the outputs of the selected input pipeline according to the overlay manager z-order configuration.
The output of each OVR is connected to the Color Phase Rotation (CPR) unit through a gamma table of the corresponding video port.
