2.4.6 Filling PIP Picture with Color
The whole inset picture can be filled with the frame color (FRCOL = ‘1’) or the luminance
value for the full screen background insertion without colors (BCKCOL = ‘1’,
FRCOL = ‘0’). The frame elements remain visible. Filling the PIP picture with
background is especially useful before starting a tuner scanning cycle.
2.4.7 Wipe-In/Wipe-Out Facility
With the wipe-in/wipe-out function it is possible to make appear or disappear the
complete inset picture starting or ending at the lower right corner of the inset picture
position. Thereby the size of the picture is continuously increased and decreased
respectively. During this procedure the frame is shown with its chosen widths. 4 different
periods are programmable via I²C Bus.
2.4.8 Output Formats and RGB Conversion
Different output formats are available: luminance signal Y with inverted or non-inverted
chrominance signals (B-Y), (R-Y) or RGB signals.
For the RGB conversion 3 matrices are provided:

Matrix selection is done via I²C Bus. The matrices are designed for the following
voltages at the inputs of the ADC converter (the values correspond to 100 % white and
75 % color saturation):
