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 available only in the
ancillary data stream. A special mode enables one line of data to
be read back through I
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

The recovered data is not available through I
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 50.
The default value does not apply to readback registers.
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[0] configures the way in which data is
embedded in the video data stream.

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). See Table 74 and Table 75
for information about how the data is packaged in the ancillary
data stream when this bit is set low.
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.
Setting GDE_SEL_OLD_ADF to 0 (default) enables a new
ancillary data system for use with the VDP and VBI System 2.
Setting GDE_SEL_OLD_ADF to 1 enables the old ancillary
data system for use with the VBI System 2 only (ADV7183B
compatible).
The format of the data packet depends on the following criteria:
•
•
•
Data packets are output if the corresponding enable bit is set
(see the GDECEL[15:0], Gemstar Decoding Even Lines,
Address 0x48[7:0], Address 0x49[7:0] and the GDECOL[15:0],
Gemstar Decoding Odd Lines, Address 0x4A[7:0], Address
0x4B[7:0] sections), and the decoder detects the presence of data.
For video lines where no data is decoded, no data packet is output,
even if the corresponding line enable bit is set.
