Timecode Processor
As illustrated in Figure 1.1 , this function provides for extraction of timecode data from the input
video, and in turn re-insertion of timecode data into the output SDI or analog composite. In this
manner, timecode data can be preserved, even after format conversion. The function can monitor
the SDI video input of the card for supported timecode formats and convert the timecode to either
or both ATC_VITC or VITC waveform (with selectable odd/even field line number control).
ATC_VITC and VITC waveform outputs are available on SD-SDI outputs; VITC waveform only
is available on CVBS outputs.
