Selecting The Lines To Record Vitc On; Selecting The Generator Drop Frame Mode (Ntsc Only) - evertz 8010-SIE Instruction Manual

3.5.5. Selecting the Lines to Record VITC On.

GEN VITC LINE 1
Gvitc line 1 = 10
It is recommended that two non-adjacent lines are used, however adjacent lines
and a single line (selected when both lines are the same) are permitted.

3.5.6. Selecting the Generator Drop Frame Mode (NTSC only)

In NTSC, the video frame rate of approximately 29.97 frames per second causes an error between real
time and 'colour time'. To overcome this problem, the drop frame mode was created. This mode
compensates for the approximate 4 minute per day error by dropping the first two frame counts (0, 1) at
the start of each minutes, except minutes 0, 10, 20, 30, 40, and 50. A drop frame flag bit is set in the
code when the drop frame format is used. When the 8010-SIE is operating in the NTSC (525 line)
video standard, the generator may be programmed to operate in either the drop frame or non drop
frame mode.

The user will have to determine by experience the most suitable lines
for recording VITC according to the following criteria.
In order to protect the VITC reading process against dropouts, the VITC
is usually repeated on 2 non-adjacent lines in the vertical interval of the
video signal, not earlier than line 10 (6 for PAL) or later than line 32.
For certain recordings, the use of some of these lines may interfere
with other signals inserted into the vertical interval.
