As of V18.104.22.168.3, non-legacy Videon devices were updated with support for SMTPE-344-2 608/708 Closed Captions via SDI input for HD/UHD resolutions.
The current behaviors of closed captions on our products are the following:
- Input caption data must be SMTPE-344-2 and can be 608 or 708
- On output the captions will be wrapped/packaged as 708
- When the user selects SDI input and the SDI input contains closed caption data (embedded in the VANC) the encoder will include this data in the transport stream outputs
