Description
VITC on PES:
Extraction of VITC data from
Line 16 or 22 for 625-line
systems (EBU definitions) or
Line 14 for 525-line systems.
For Standard Definition Encoders only.
Enabling this option will disable VBI on PID.
VBI on PID:
Turns the transmission of
VBI data on its own PID 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 to 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 and as such
will be subject to some distortion. 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:
Selects the extended picture
format available in the
MPEG 4:2:2 specification.
The VBI in Picture option is
only accessible if the
selected video profile/level is
422P@ML (E5780: 4:2:2 is
available when software
option M2/ESO2/422 is
purchased).
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:
On/off
SDI/VANC PID:
Enter PID using softkeys.
SDI/VANC Tag:
Enter Tag using softkeys.
On (Video 21 & 284)
On (Video Line 21)
On (SD-SDI/SMPTE 334M)
This option controls the extraction and processing of closed caption data by
the Encoder. Closed caption data can be obtained from: video line 21, video
lines 21 and 284, or be received in accordance with SMPTE 333M and SMPTE
334M on HD-SDI.
Closed Caption
The Encoder automatically converts EIA608 to EIA708 format. The “CC…” settings are used in this conversion.
Field 1 Captions:
Sets the appropriate
descriptors in the PSIP
information.
It allows the number of CC services, from the source, contained in-Field 1 to be
entered.
Only available if Closed Captions = On (Video 21) or On (Video 21 & 284).
