CEA608/708
•
CEA-608/708 Output Enable:
Enables embedding of CEA-608 captioning as a line
21 signal in 525 output video, and CEA-708 captioning as an embedded VANC packet
in 59 Hz HD output video.
Note: The Output Enable controls only enable embedding of output closed captioning.
For closed captioning to be present in the output video, valid input closed captioning
must be detected, and you must select the correct output standard to support
pass-through or transcoding.
•
Output Line:
Selects the output line on which to insert CEA-708 VANC packets. The
range is from line 8 to line 20 in one-line steps. The default is line 10.

5.13.2 Multi-line WST
The unit can pass World System Teletext (WST) for SD and RDD-08 or SMPTE 2031 teletext
for HD. You can enable or disable teletext output and specify the input and output lines used.
Teletext covers World System Teletext (WST) subtitles, SMPTE RDD-08 and SMPTE 2031.
For WST and RDD-08, only subtitle information is supported or processed. SMPTE 2031
VANC packets may be teletext subtitles, non-subtitles, or inverted teletext.
WST is only supported in 625 input or output encoded signals. RDD-08 is only supported in
50 Hz HD video standards as a VANC packet with a Subtitling Distribution Packet (SDP)
payload. Teletext subtitle transcoding is supported from WST to RDD-08 by taking the
