Model 7400 HD/SD and Model 9400 3G/HD/SD Sync Pulse Generator and Test Signal Generator
Vertical Interval Timecode (VITC) and Digital Vertical Interval Timecode
(DVITC)
The 7400 and 9400 offer the following ways to have Vertical Interval Timecode (VITC) and Digital
Vertical Interval Timecode (DVITC):
1. The Analog Composite output of each generator (User-Programmable Output 1) can have VITC
carried in the vertical interval.
2. When the SDI output is standard definition, it can have VITC in the vertical interval. This is basically
a digitized version of the VITC that would be in an analog composite signal.
3. When the SDI output is high definition, it can have DVITC packets carried in the ancillary data
spaces.
4. When a 7400 GPS option is installed, VITC and DVITC are available from the GPS.
Locking to a Black Burst Signal with VITC
Models 7400 and 9400 can lock to a black burst signal which has VITC in it. In that case, the timecode
generator in the 7400 or 9400 will track that VITC reference.
