LTC Reader
LTC reader will accept LTC at rates between 1/30 and 80 times the
nominal rate in either forward or reverse directions.
LTC Transmitter
LTC transmitter outputs LTC at the nominal frame rate for the selected

Parameter
Specification
VITC waveform
lines 10-20 NTSC (525 Line); lines 10-22 PAL (625 Line)
VITC is decoded on each SDI input and inserted on each SDI output.
VITC Reader configurable for a search window (specified by two lines)
or set to manual mode (based on two specified lines).
VITC Writer inserts VITC data on two selectable lines per field in the
vertical interval. The two lines have the same data.
VITC is not decoded off of the video reference input.
