9921-FS Functional Description
1-12 9921-FS PRODUCT MANUAL 9921-FS-OM (V1.15)
Timecode Processor
(See Figure 1-4.) This function uses extracted timecode data from the input
video (waveform or ATC), reference VITC waveform, or internal (free run)
and in turn re-inserts selected timecode data into the program video signal.
The function can monitor video input and reference input for supported
timecode formats, and then select and prioritize among SDI VITC waveform,
SDI ATC_VITC, and SDI ATC_LTC timecode sources. If the preferred
format is detected, the preferred format is used by the card; if the preferred
format is not detected, the card uses other formats (where available) as
desired.
The function also provides conversion between various timecode formats and
provides independent insertion and line number controls for each SDI
timecode output format. When licensed with option
+LTC , this function also
can receive, send and translate between audio/RS-485 LTC timecode formats
and the VBI formats described above. Refer to catalog or Fusion3G
® manual
supplement OPT-F3GLTC-MS for more information.
