SFL_INV Subcarrier Frequency Lock Inversion (SDP)
This bit controls the behavior of the PAL switch bit in the SFL
(GenLock Telegram) data stream. It was implemented to solve
some compatibility issues with video encoders. It solves two
problems:
1.
The PAL switch bit is only meaningful in PAL. Some
encoders (including Analog Devices encoders) also look at
the state of this bit in NTSC.
2.
There was a design change in Analog Devices encoders
from ADV717x to ADV719x. The older versions used the
SFL (GenLock Telegram) bit directly, while the later ones
invert the bit prior to using it. The reason for this is that the
inversion compensated for the 1-line delay of an SFL
(GenLock Telegram) transmission.
As a result:
1.
ADV717x encoders need the PAL switch bit in the SFL
(GenLock Telegram) to be 1 for NTSC to work.
2.
ADV7190/ADV7191/ADV7194 encoders need the PAL
switch bit in the SFL to be 0 to work in NTSC.
If the state of the PAL switch bit is wrong, a 180°phase shift
occurs.
In a decoder/encoder back-to-back system in which SFL is used,
this bit must be set up properly for the specific encoder used.
