Preliminary specication
Picture-in-Picture (PIP) controller for NTSC
SAB9075H
PIP modes
The controller contains two independent acquisition-channels which provide the scaling factors to support the range of
different modes. With the external memory of 2 Mbit it is possible to select between single, double and multi-PIP modes.
Table 2 gives an overview of the different PIP modes.

PIP modes
Notes
1. The given sub/main sizes are visible PIP sizes, a border is drawn around these PIPs and does not influence these
sizes. The size of the border is 4 pixels wide and 2 lines/fields high.
2. The SAB9075H can be set in automatic mode in which the reduction factors are automatically set by the mode select
and aspect ratio select bits of the I2C-bus. If the automatic mode is switched OFF the reduction factors can be set
manually. This will give more flexibility to adjust the aspect ratios of incoming signals.
PIP positions
The positions are graphically depicted in Figs 5 to 17.
