Notes
Only closed caption data from the SDP core can be
embedded in the output data stream. PAL closed caption
data is sliced from lines 22 and 335. The corresponding
enable bits have to be set.
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.
