13.4.1.Introduction
The VDP 313xY is a video IC family of high-quality single-chip video processors. Modular design and a
sub-micron technology allow the economic integration of features in all classes of TV sets. The VDP
313xY family is based on the VDP 31xxB including YC
R
C
B
inputs for DVD component signals.
The VDP 313xY includes complete video, display and deflection processing. All processing is done
digitally, the video frontend and video backend are interfacing to the analog world. Most functions of the
VDP can be controlled by software via I
2 C-Bus interface
