9.3.4. VITS (Vertical Interval Test Signals) Parameter
The ProView 2900 supports 10 different VITS signals: 4 signals for PAL, 2 signals for NTSC
and 4 signals for SECAM and Russian SECAM. The VITS signals are automatically selected
according to the selected video format (PAL, TSC or SECAM/R.SECAM).
The PAL and NTSC VITS signals are according to ITU-T J.63 standard:
 PAL- Lines 17, 18, 330, 331
 NTSC- Line 17 Field 1, Line 17 Field 2
 SECAM/R.SECAM- Lines 17, 18, 330, 331
When working in PAL or SECAM/R.SECAM video format, the user can select two lines.
The factory setting is to Line 1: 17 and Line 2: 18. In this case, the ProView 2900 will re-insert
the VITS signals automatically to lines 17, 18, 330, 331.
In the case of selecting different line numbers for VITS, the ProView 2900 calculates the new
line numbers in which to re-insert the VITS signals. For example, changing Line 2 to 19
(instead of 18) will result in VITS signals re-inserted to lines: 17, 19, 330 and 332.
When the VBI Vertical Interval Test Signals (VITS) parameter is selected, the following
