Data insert
Teletext and sub-titles: UP-DOWN-ATX-VF and UP-DOWN-ATXS-VF support both OP-47
and SMPTE 2031. When up converting, they will take the teletext data
(System B to ITU-R BT 653-3) out of the SD coded signal and put the
same data in the OP-47 or SMPTE 2031 data stream they create. An
HD output can only contain SMPTE 2031 or OP-47, not both. When
down converting they can take teletext data out of OP-47 or SMPTE
2031 packets and encode it as an SD output. If going from HD to HD,
they can be used to convert from SMPTE 2031 to OP-47 or vice versa.
It is possible to specify which line in the VANC space is used to carry
SMPTE 2031 or OP-47.
Closed caption: When down converting 59.94Hz video, UP-DOWN-ATX-VF and UP-
DOWN-ATXS-VF can take the closed caption data from CEA-708 and
output the corresponding CEA-608 waveform. When up converting they
will decode the CEA-608 waveform and insert the data into the
appropriate section of CEA-708 on the 3G/HD output.
Timecode: Can pass Ancillary Timecode from the input to the output. The Ancillary
Timecode can be used to get the interlace timing correct and maintain a
correct field sequence when down converting. When up converting, can
read Digital Vertical Interval Timecode (DVITC, SMPTE 266M-2002) on
the SD input and translate it to Ancillary Timecode (ATC, SMPTE 12M-
2-2008) on the HD output. When down converting, can take in timecode
as ATC ancillary data and can generate DVITC.
AFD,WSS,VI: SMPTE 2016 AFD, SMPTE RP186 WSS and ETSI EN 300 294 Video
index data can be extracted and/or inserted.
