GDECEL[15:0] Gemstar Decoding Even Lines (SDP),
Address 0x48, [7:0]; Address 0x49, [7:0]
The 16 bits of the 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 164 and Table 165.
Rev. A | Page 61 of 104
Notes
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.
Table 161. GDECEL Function
GDECEL[15:0]
Description
0x0000*
Do not attempt to decode Gemstar compatible
data or CCAP on any line (even field).
*Default value.
GDECOL[15:0] Gemstar Decoding Odd Lines (SDP),
Address 0x4A, [7:0]; Address 0x4B, [7:0]
The 16 bits of the GDECOL[15:0] form a collection of 16
individual line decode enable signals. See Table 164 and
Table 165.
Notes
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.
Table 162. GDECOL Function
GDECOL[15:0]
Description
0x0000*
Do not attempt to decode Gemstar
compatible data or CCAP on any line (odd
field).
*Default value.
GDECAD Gemstar Decode Ancillary Data Format (SDP),
Address 0x4C, [0]
The decoded data from Gemstar compatible transmissions or
closed caption is inserted into the horizontal blanking period of
the respective line of video. There is a potential problem if the
retrieved data bytes have the value 0x00 or 0xFF. In an ITU-R
BT.656 compatible data stream, those 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:
Insert all data straight into the data stream, even the
reserved values of 0x00 and 0xFF, if they occur. This may
violate the 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.
Table 163. GDECAD Function
GDECAD
Description
0*
Split data into half-bytes and insert.
1
Output data straight in 8-bit format.
*Default value.
