Abstract
A system and method for flexibly blending multiple image planes in a video device comprises a timing controller configured to generate adjusted synchronization signals for pretiming multiple video image planes. The timing controller preferably generates the adjusted synchronization signals in response to programmable delay signals and a master synchronization signal. A blender device then receives and flexibly combines the multiple video image planes to generate a synchronized composite blender output signal. The blender preferably includes a selectable pseudo-output signal that may be routed through an external processing device, and returned as a feedback loop to an external input of the blender device.
