VITC Support

The Electra™ 9200 supports extraction of Vertical Interval Time Code (VITC) data placed into
VANC or HANC per SMPTE RP188. The VITC data is used to synchronize DPI events on both
HD and SD encoders. HD encoders receive VITC input carried in the Vertical Ancillary data
space (VANC) or Horizontal Ancillary data space (HANC) of a 292MB stream.
