An overlay manager (OVR) is responsible for compositing selected input layers together to generate the final display output frame. DISPC implements two identical overlay managers (see Figure 12-465, 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.
The DISPC overlay managers, OVR1 and OVR2, will be commonly referred to as overlay manager (OVR) in the following sections.
