GDECOL[15:0], Gemstar Decoding Odd Lines,
Address 0x4A[7:0], Address 0x4B[7:0]
The 16 bits of GDECOL[15:0] form a collection of 16 individual
line decode enable signals. See Table 96 and Table 97.
To retrieve closed caption data services on NTSC (Line 21),
GDECOL[11] must be set.
To retrieve closed caption data services on PAL (Line 22),
GDECOL[14] must be set.
The default value of GDECOL[15:0] is 0x0000. This setting
instructs the decoder not to attempt to decode Gemstar or CCAP
data from any line in the odd field. The user should only enable
Gemstar slicing on lines where VBI data is expected.

GDECAD, Gemstar Decode Ancillary Data Format,
Address 0x4C[0]
The decoded data from Gemstar-compatible transmissions or
closed caption-compatible transmissions is inserted into the
horizontal blanking period of the respective line of video. A
potential problem can arise if the retrieved data bytes have a
value of 0x00 or 0xFF. In an ITU-R BT.656-compatible data
stream, these values are reserved and used only to form a fixed
preamble. The GDECAD bit allows the data to be inserted into
the horizontal blanking period in two ways:
When GDECAD is 0 (default), the data is split into half-bytes
and inserted.
When GDECAD is 1, the data is output straight into the data
stream in 8-bit format.

Insert all data straight into the data stream, even the
reserved values of 0x00 and 0xFF, if they occur. This may
violate output data format specification ITU-R BT.1364.
Split all data into nibbles and insert the half-bytes over
double the number of cycles in a 4-bit format.
