signal.
Input read parameter
The figure below shows applications of the picture insert mode. For this feature an additional PIP
circuit (e.g. SDA 9388, SDA 9488/89) is necessary. Together with the PIP IV circuit (SDA 9488/89)
also split screen applications like double window are possible. The compression of the inserted
picture has also be done by the external PIP or front-end processor.
Picture insert mode: application examples picture tracking, random pictures

Input signals
The SDA 9401 accepts at the input side the sample frequency relations of Y : (B-Y) : (R-Y): 4:2:2
and CCIR 656. In case of CCIR 656 three modes are supported (FORMAT=11 means full CCIR 656
support, including H-, V-Sync and Field signal, FORMAT=01 means only data processing, H- and
V-Sync have to be added separately according PAL/NTSC norm, FORMAT=10 means only data
processing, H- and V-sync have to be added separately according CCIR656-PAL/NTSC norm). The
representation of the samples of the chrominance signal is programmable as positive dual code
(unsigned, parameter TWOIN=0) or two's complement code (TWOIN=1, see also
chapter I2C bus
format
on page 45, I2C bus parameter 00h). Inside the SDA 9401 all algorithms assume positive
dual code.
