PIP Controller
Preliminary Overview
The LC74411N and LC74411NE are digital processing controllers for PIP (picture-in-picture) systems in TV sets a n d VCRs. These ICs incorporate three circuits, a m u l t i p l e x e d A/D converter, field memory, and a D/A converter, to implement the PIP digital processing block in a single chip.
