The default value does not apply to readback registers.
VBI System 2
The user has an option of using a different VBI data slicer called
VBI System 2. This data slicer is used to decode Gemstar and
closed caption VBI signals only.
Using this system, the Gemstar data is only available in the
ancillary data stream. A special mode enables one line of data to
be read back through I
2
C. For details about using I
2
C readback
with the VBI System 2 data slicer, contact local Analog Devices
field applications engineers or local Analog Devices distributor.
Gemstar Data Recovery
The Gemstar-compatible data recovery block (GSCD) supports
1× and 2× data transmissions. In addition, it can serve as a
closed caption decoder. Gemstar-compatible data transmissions
can occur only in NTSC. Closed caption data can be decoded in
both PAL and NTSC.
The block can be configured via I
2
C as follows:
GDECEL[15:0] allows data recovery on selected video lines
on even fields to be enabled or disabled.
GDECOL[15:0] enables the data recovery on selected lines
for odd fields.
GDECAD configures the way in which data is embedded
in the video data stream.
The recovered data is not available through I
2
C, but is inserted into
the horizontal blanking period of an ITU-R BT.656-compatible
data stream. The data format is intended to comply with the
recommendation by the International Telecommunications
Union, ITU-R BT.1364. For more information, visit the
International Telecommunication Union website. See Figure 47.

GDE_SEL_OLD_ADF, Address 0x4C [3], User Sub Map
The ADV7180 has a new ancillary data output block that can be
used by the VDP data slicer and the VBI System 2 data slicer.
The new ancillary data formatter is used by setting
GDE_SEL_OLD_ADF to 0 (default). If this bit is set low, refer
to Table 70 and Table 71 for information about how the data is
packaged in the ancillary data stream.
To use the old ancillary data formatter (to be backward compatible
with the ADV7183B), set GDE_SEL_OLD_ADF to 1. The ancillary
data format in this section refers to the ADV7183B-compatible
ancillary data formatter.
0 (default)—Enables new ancillary data system for use with
VDP and VBI System 2.
1—Enables old ancillary data system for use with VBI System 2
only (ADV7183B compatible).
The format of the data packet depends on the following criteria:
Transmission is 1× or 2×.
Data is output in 8-bit or 4-bit format (see the description
of the bit).
Data is closed caption (CCAP) or Gemstar compatible.
Data packets are output if the corresponding enable bit is set
(see the GDECEL[15:0] and GDECOL[15:0] descriptions) the
decoder detects the presence of data. This means that for video
lines where no data has been decoded, no data packet is output
even if the corresponding line enable bit is set.
