Please consider these points while configuring a Playout of Closed Captions.
We
onlysupport devices from AJA and BMD for CC playout.
AJA supports only a single output to carry the CC data. Using a device from BMD, all outputs available also carry the CC data.
The output of CC data is currently not supported for channels set up to play out fill and key using a device from BMD.
To be able to pass through CC data embedded into the Live Signal, an AJA Io4K+, Kona 4 or Kona 5 is needed or a "4K" device from BMD.
CC of the Live Signal may be on lines 9 through 20. The incoming signal is automatically scanned for caption data.
Playing out QuickTime MOV Videos, line-21 burn-in, the CC data track
as well as MCC and SCC sidecar files are supported for Closed Captions.- When playing out MXF Videos, sidecar files in both SCC and MCC formats are now supported for Closed Captions. This includes files written by just:in.

When playing out NTSC SD with Closed Captions enabled
just:out now, Just Out always sends CEA-608 CC packets. For media with CEA-708 CC packets these will be wrapped into CEA-608 CC packets whenever possible.

.CEA-608 and CEA-708Closed Captions can be added directly to the outgoing RTMP stream. Please verify with your CDN that CC are supported.
