LTC reader will accept LTC at rates between 1/30 and 80 times the
nominal rate in either forward or reverse directions. LTC Reader
LTC transmitter outputs LTC at the nominal frame rate for the
selected standard at 1x speed, forward direction only. LTC Transmitter
VITC Input/Output
The K2 Summit/Solo system specification is shown in the following table.
Specification Parameter
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.
VITC waveform
RS-422 specification K2 Summit 3G system
The RS-422 interface conforms to ANSI/SMPTE 207M-1997 standard (SMPTE 422).
