Component
Comments
Closed Captions
Via SMPTE 334 (extracted from VANC data - 29.97Hz operation only) and
carried in the 'Picture User data' (user_data_registered_itu_t_t35 SEI
message) of the video stream as per ATSC A/72 part 1
Generic VANC
Up to 2 MBit/s of ANC data (excluding embedded audio) can be extracted and
carried in the VBI component as defined in SMPTE 2038.
Time Code
Via SMPTE 12-2 (extracted from VANC data) and carried in the elementary
stream (in the pic_timing SEI message) and the transport stream adaptation
layer as per ETSI TS101 154
OP-47 (Subtitles)
Teletext subtitles are extracted from ANC in accordance with OP-47 and carried
in a teletext PID.
