Selected Item Options Description
VBI Line ‘n’ Option For Standard Definition Encoders only.
Each VBI line can be individually configured as to the format of VBI data that
should be extracted from that line. However, a maximum of eight VBI lines can
be processed per field (this does not include Teletext lines).
Option Description
Frame Rate = 29.97 Hz
Off VBI data is not extracted from the line.
VANC data-piping When the “VANC on PES” menu option is set to “On” the data from each ‘VBI line’ that has “VANC
data-piping” selected is inserted onto a separate PES packet and encapsulated into the transport stream
on the PID specified in the “VANC PID” menu.
Vertical Interval Time
Code VITC data extracted from the line.
Video Index
Closed Caption
Indicates that closed
captioning data is
extracted. The setting cannot be selected on this screen, but is set by setting the Closed Caption option to On
[SMPTE 333M], On [video 21 & 284] or On [video line 21]. Setting Line 21 back to Off or VITC resets the
Closed Caption option back to Off.

Off VBI data is not extracted from the line.
VANC data-piping When the “VANC on PES” menu option is set to “On” the data from each ‘VBI line’ that has “VANC
data-piping” selected is inserted onto a separate PES packet and encapsulated into the transport stream
on the PID specified in the “VANC PID” menu.
Vertical Interval Time
Code VITC data extracted from the line.
Video Index Aspect ratio will be affected.
Teletext System B
(World System Teletext) Teletext System B data extracted from the line. When Teletext = On 7-22 and 320-335, those lines carry
Teletext data. It is possible to extract Teletext from lines 6, 318 and 319 as well, but these lines must be
individually configured.
Inverted Teletext Inverted Teletext is extracted from the line.
Wide Screen Signalling
Indicates that WSS data
is extracted. The setting cannot be selected on this screen, but is set by setting the WSS (Line 23) option to On. Setting
Line 23 back to Off, VITC or Teletext System B resets the WSS (Line 23) option back to Off.
Closed Caption Closed Caption data is extracted from the line.
Video Programming
System
The setting cannot be selected on this screen, but is set by setting the VPS (Line 16) option to On. It
indicates that VPS data is extracted from the line. Setting Line 16 back to Off, VITC or Teletext System B
resets the VPS (Line 16) option back to Off.
When operating in ATSC mode and Closed Captions, the language of the descriptors is set by the Encoder.
When switching the Encoder from DVB to ATSC mode the PIDs are remapped. The remapping would be
specified by the program paradigm. Switching back to DVB would invoke the original PIDs.
NOTES…
1. To autodetect VITC the lines within the VBI line option must be set to VITC (SD only).
2. VITC is carried as timecode in the video stream rather than as a separate PES
stream. If VITC is not present, a locally generated timecode is sent instead.
3. From SV 3.6.0, VITC data can be carried in PES.
4. In HD only Teletext and Vertical Timecode are available.
