PFTOGSIGN, PAL Field Toggle Sign, Address 0xEA [5]
0—Delays the field transition. Set for manual programming.
1 (default)—Advances the field transition. Not recommended
for user programming.
PFTOG, PAL Field Toggle, Address 0xEA [4:0]
The default value of PFTOG is 00011, indicating the PAL field
toggle position.
For all NTSC/PAL field timing controls, the F bit in the AV code
and the field signal on the FIELD/DE pin are modified.

SYNC PROCESSING
The ADV7188 has two additional sync processing blocks that
postprocess the raw synchronization information extracted
from the digitized input video. If desired, the blocks can be
disabled via the following two I
2
C bits.
ENHSPLL, Enable Hsync Processor, Address 0x01 [6]
The hsync processor is designed to filter incoming hsyncs that
have been corrupted by noise; therefore, it improves the per-
formance of the ADV7188 for video signals with stable time
bases but poor SNR.
0—Disables the hsync processor.
1 (default)—Enables the hsync processor.
ENVSPROC, Enable Vsync Processor, Address 0x01 [3]
This block provides extra filtering of the detected vsyncs to
improve vertical lock.
0—Disables the vsync processor.
1 (default)—Enables the vsync processor.
VBI DATA DECODE
There are two VBI data slicers on the ADV7188. The first is
called the VBI data processor (VDP), and the second is called
the VBI System 2.
The VDP can slice both low bandwidth standards and high
bandwidth standards, such as teletext. VBI System 2 can slice
low data rate VBI standards only.
The VDP is capable of slicing multiple VBI data standards on
SD video. It decodes the VBI data on the incoming CVBS and
Y/C or YUV data. The decoded results are available as ancillary
data in the output 656 data stream. For low data rate VBI standards
such as CC/WSS/CGMS, the user can read the decoded data
bytes from I
2
C registers. The VBI data standards that can be
decoded by the VDP are shown in
Table 64 and Table 65.

The VBI data standard that the VDP decodes on a particular
line of incoming video has been set by default, as described in
Table 66. This can be overridden manually, and any VBI data
can be decoded on any line. The details of manual program-
ming are described in
Table 67 and Table 68.
VDP Default Configuration
The VDP can decode different VBI data standards on a line-to-
line basis. The various standards supported by default on different
lines of VBI are explained in
Table 66.
