ST 2110-40 ancillary sender. Transports SMPTE 291 VANC packets (CCs, SCTE-104 splice commands, AFD, timecode, etc.) at the paired video session’s frame rate. Wire SDP advertises m=video application/smpte291 90000 — the video media type is per RFC 8331 even though the payload is data.

ST2110SenderSender.SubtitleSender

ST 2110-40 subtitle sender. Wire-identical to AncillarySender — same SMPTE 291 / RFC 8331 framing, same SDP — but accepts Subtitle stream inputs (CEA-708 / CEA-608 / OP-47) instead of Ancillary stream inputs. Discriminated at the PS sender layer so the Outputs/ST2110 pin generators can be narrowly typed. A wire stream that needs to carry both subtitles AND ancillary today takes two separate senders (one of each).

ST2110SenderSender.TtmlSender

ST 2110-43 TTML sender. Wire is RFC 8759 over its own RTP session at 90 kHz; SDP advertises m=application … RTP/AVP <pt>, a=rtpmap:<pt> ttml+xml/90000, mandatory a=fmtp:<pt> codecs=<imsc-short>. Accepts Subtitle stream inputs with a ttml payload row.
