Selected Item Options Description
VITC on PES Option:
Extraction of VITC data from
VBI lines. For Standard Definition Encoders only.
Enabling this option disables the VBI on PID option.
VBI on PID:
Allows the transmission of
VBI data on its own PID to
be turned On or Off.
VBI PID:
Defines the PID to be used
for VBI data.
VBI Component Tag:
Sets the component tag for
the VBI stream. 0-255
On VBI is coded as active video.
Off
Off ( bitrate too low) Insufficient bitrate.
For Standard Definition Encoders only.
When selected, the Encoder compresses and transmits the VBI data as part of the active picture. Most
analogue VBI types are robust against this type of distortion but others, e.g. video index and ITS, are intended
for SDI transmission and will not survive MPEG coding/decoding in VBI in Picture mode. This mode requires up
to 3 Mbit/s of bitrate, depending on the amount and complexity of the VBI present. It may be necessary to
increase the video bitrate accordingly to maintain picture quality.
When this option is not selected (or when 4:2:0 format video is used), VBI data must be transmitted in its
original digital form either in an independent data stream (in the case of Teletext) or in user data fields within
the MPEG video transport stream.
VBI In Picture Option:
Enables the extended
picture format available in
the MPEG 4:2:2 specification
to be selected.
The VBI in Picture option is
only accessible if the
selected video profile/level is
422P@ML
3 .
CAUTION…
When encoding VBI in this way 3:2 Pull-down should be switched off. If it is not, then
occasionally fields may not be encoded because of the inverse pull-down process. This
results in some VBI lines not being transmitted.
SDI/VANC on PES: Off The default is off
On
Closed Caption data and any user data embedded in the SD-SDI according to
SMPTE 334, is extracted and sent via PID, carried in the Transport Stream in
accordance to the ARIB STD-B40 ver.1.0 format.
The PID shall be signalled as ‘PES private data’. (Stream type 6).
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.
SDI/VANC PID:
Enter PID using softkeys. 0x1FDO to 0x1FEF The default is 0x1FD0
SDI/VANC Tag:
Enter Tag using softkeys. 0 to 255 The default is 196. The tag ID is added to the PMT descriptor for the VANC
data component when present.
When 0 is selected the descriptor is removed from the PMT.
On (Video 18 & 331)
On (Video 18)
On (SD-SDI/SMPTE 334M)
Closed Caption
Off
This option controls the extraction and processing of closed caption data by
the Encoder. Closed caption data can be obtained from: video line 18, video
lines 18 and 331, or be received in accordance with SMPTE 334M on SD-SDI.

For the E5780 Encoder, 4:2:2 is only available when software option M2/ESO2/422 is enabled.
