Description
VBI Line ‘n’
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.
Vertical Interval Time
Code
VITC data extracted from the line.
Video Index
Closed Caption
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]. It indicates that closed captioning data is
extracted from the line. Setting Line 21 back to Off or VITC resets the Closed Caption option to Off.

The setting cannot be selected on this screen, but is set by setting the WSS (Line 23) option to On. It
indicates that WSS data is extracted from the line. Setting Line 23 back to Off, VITC or Teletext System

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.
To autodetect VITC the lines
within the VBI line option
must be set to VITC (SD
only).
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.
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.
In HD only Teletext and Vertical Timecode are available.
Time Code in Userdata:
Used to insert a time code
into userdata as defined by
SMPTE 328.
On/Off
For High Definition Encoders only.
Only the time code section of SMPTE 328 is implemented, along with
appropriate headers.
