NTSC CCAP Data
Half-byte output mode is selected by setting GDECAD to 0, and
the full-byte mode is enabled by setting GDECAD to 1. See the
GDECAD, Gemstar Decode Ancillary Data Format, Address
0x4C[0] section. The data packet formats are shown in Table 92
and Table 93. Only closed caption data can be embedded in the
output data stream.
NTSC closed caption data is sliced on Line 21 of even and odd
fields. The corresponding enable bit must be set high. See the
GDECAD, Gemstar Decode Ancillary Data Format, Address
0x4C[0] section and the GDECOL[15:0], Gemstar Decoding
Odd Lines, Address 0x4A[7:0], Address 0x4B[7:0] section.
PAL CCAP Data
Half-byte output mode is selected by setting GDECAD to 0, and
full-byte output mode is selected by setting GDECAD to 1. See
the GDECAD, Gemstar Decode Ancillary Data Format,
Address 0x4C[0] section. Table 94 and Table 95 list the bytes of
the data packet.
Only closed caption data can be embedded in the output data
stream. PAL closed caption data is sliced from Line 22 and
Line 335. The corresponding enable bits must be set.

See the GDECEL[15:0], Gemstar Decoding Even Lines,
Address 0x48[7:0], Address 0x49[7:0] section and the
GDECOL[15:0], Gemstar Decoding Odd Lines,
Address 0x4A[7:0], Address 0x4B[7:0] section.
GDECEL[15:0], Gemstar Decoding Even Lines,
Address 0x48[7:0], Address 0x49[7:0]
The 16 bits of GDECEL[15:0] are interpreted as a collection of
16 individual line decode enable signals. Each bit refers to a line
of video in an even field. Setting the bit enables the decoder block
trying to find Gemstar or closed caption-compatible data on
that particular line. Setting the bit to 0 prevents the decoder
from trying to retrieve data. See Table 96 and Table 97.
To retrieve closed caption data services on NTSC (Line 284),
GDECEL[11] must be set.
To retrieve closed caption data services on PAL (Line 335),
GDECEL[14] must be set.
The default value of GDECEL[15:0] is 0x0000. This setting
instructs the decoder not to attempt to decode Gemstar or
CCAP data from any line in the even field. The user should
only enable Gemstar slicing on lines where VBI data is expected.
