This register contains the LSBs of the count specifying where to stop generating raw VBI
data in two sample clock steps from the 50% point of the leading edge of HSYNC.
This register contains the MSBs of the count specifying where to stop generating raw VBI
data in two sample clock steps from the 50% point of the leading edge of HSYNC.
For a “1” in each bit position, the line that the bit corresponds to will be converted into raw
A/D data. A “0” in the bit position will disable the line from being converted to raw A/D data.
Bit 0 corresponds to line 9 (odd field) and 272 (even field) for 525 line systems and to line
5 (odd field) and 318 (even field) for 625 line systems. Bit 7 corresponds to line 16 (odd
field) and 279 (even field) for 525 line systems and to line 12 (odd field) and 325 (even
field) for 625 line systems.
For a “1” in each bit position, the line that the bit corresponds to will be converted into raw
A/D data. A “0” in the bit position will disable the line from being converted to raw A/D data.
Bit 0 corresponds to line 17 (odd field) and 280 (even field) for 525 line systems and to
line 13 (odd field) and 326 (even field) for 625 line systems. Bit 7 corresponds to line 24
(odd field) and 287 (even field) for 525 line systems and to line 20 (odd field) and 333
(even field) for 625 line systems.
For a “1” in each bit position, the line that the bit corresponds to will be converted into raw
A/D data. A “0” in the bit position will disable the line from being converted to raw A/D data.
Bit 0 corresponds to line 25 (odd field) and 288 (even field) for 525 line systems and to
line 21 (odd field) and 334 (even field) for 625 line systems. Bit 2 corresponds to line 27
(odd field) and 290 (even field) for 525 line systems and to line 23 (odd field) and 336
(even field) for 625 line systems.
