7-0
Raw VBI Line
Mask_7_0
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.
