NTSC CCAP Data
Half-byte output mode is selected by setting CDECAD = 0, the
full-byte mode is enabled by CDECAD = 1. See the GDECAD
Gemstar Decode Ancillary Data Format (SDP), Address 0x4C,
[0]. The data packet formats are shown in Table 157 and
Table 158.
Notes
Only closed caption data from the SDP core can be
embedded in the output data stream.
NTSC closed caption data is sliced on line 21
d
on even and
odd fields. The corresponding enable bit has to be set high.
See the GDECEL[15:0] Gemstar Decoding Even Lines
(SDP), Address 0x48, [7:0]; Address 0x49, [7:0] and
GDECOL[15:0] Gemstar Decoding Odd Lines (SDP),
Address 0x4A, [7:0]; Address 0x4B, [7:0] sections.
