Input write parameter
Parameter
[Default value]
OPDEL
[170]
Subaddress
06h
Description
Delay (in number of lines) of the internal V-Sync
(delayed VIN) to the outgoing V-Sync (VOUT)
The internal line counter is used to determine the information about the standard of the incoming
signal.
Input read parameter
Parameter
TVMODE
Subaddress
33h
Description
TV standard of the incoming signal:
1: NTSC
0: PAL
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. In the picture insert mode motion
adaptive scan rate conversion modes (e.g. Soft Mix I) are not supported (see also Operation mode
generator on page 46). 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
