6.5.7.7 Transport Delay
What can be done with the Transport Delay
The first image data the projector receives from the Image Generator is the start of the first active line. However when a top side
bow pre-distortion is used, the first image data the projector needs is the image information that is halfway that first active line, to
gather all this information before projecting it on the screen, an adjustable Transport Delay is applied on the received image data.
