TABLE 28. RAW VBI LINE MASK_7_0 REGISTER
BIT
NO.
FUNCTION
SUB ADDRESS = 15_H
DESCRIPTION
RESET
STATE
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
FE_H
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.
TABLE 29. RAW VBI LINE MASK_15_8 REGISTER
BIT
NO.
FUNCTION
SUB ADDRESS = 16_H
DESCRIPTION
RESET
STATE
7-0
Raw VBI Line
Mask_15_8
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
