Vits (Vertical Interval Test Signals) Parameter - Harmonic ProView 2900 Installation Manual

Chapter 9: Video Configuration Menu

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
screen is displayed:

NOTES
The VITS signal is inserted differently if using PAL or NTSC. When selecting PAL, VITS
signals are inserted to lines 17 and 18 and to lines 330 and 331. When selecting NTSC, VITS
signals are inserted to line 17-field 1 and line 17-field 2.
