Adding captions to HLS ( M3u8 ) CEA-608


We are using JW player Enterprise on our Adobe Media server to stream HLS M3U8 videos. This works great however we are having some questions regarding using closed captions.

How does one insert CC into segmented m3U8 videos? We have our captions available in SCC (CEA-608, manually converted to support 21 lines) , VTT, SRT.

Do the CC files also have to be segmented as well or can they be implemented in some way?

Best regards.
