GDECEL[15:0] Gemstar Decoding Even Lines,
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
246H
Table 74 and
247H
Table 75.
Rev. B | Page 56 of 100
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.
GDECOL[15:0] Gemstar Decoding Odd Lines,
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
248H
Table 74 and
249H
Table 75.
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.
GDECAD Gemstar Decode Ancillary Data Format,
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 can
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.
When GDECAD is 0, the data is split into half-bytes and
inserted (default).
When GDECAD is 1, the data is output straight in 8-bit format.
