# >Video>VBI
Used to configure the encoder to transmit teletext data.
Note: Teletext should not be enable with other VBI encoding formats, as teletext
overwrites all other VBI data.
Note: For additional information on Teletext, refer to the appendix on VBI Data
Transmission.
VBI Mode Enable and selects the VBI
functions and format
? Off – Disables all VBI functions
? Tiernan CC - Configures the encoder to transmit
Tiernan closed captioning information. The
Tiernan CC transmission described in this
document is Radyne ComStream proprietary. Only
Tiernan decoders accommodate the Tiernan CC
feature described in this document:
Note: Tiernan CC should not be implemented in
PAL mode, as the closed caption information
will be decoded and placed on line 22 of the
video.
? ATSC CC - Configures the encoder to transmit
ATSC closed captioning information.
? 4:2:2 Expand - Configures the encoder to
transmit either 16 or 32 lines of VBI information
VBI
Quantization
Configures the encoder to
transmit either 16 or 32 lines of
VBI information
? Off – disables expanded windows mode
(default).
? 16-line – enables 16-line expanded windows
mode.
? 32-line – enables 16-line expanded windows
mode.
VBI Endline Sets the last line of encoded VBI
when 4:2:2 expanded windows is
enabled
? TBD
Teletext Enable Configures the encoder to
transmit teletext information.
? off – does not encode any teletext information
(default).
? all – encodes the entire VBI teletext area; i.e.,
allocates bit-rate to include maximum number of
teletext lines.
? auto – automatically allocates bit-rate to include
only the number of detected teletext lines.
Teletext Data ID Setting determines EBU data
included in the teletext. Values
from 0x10 to 0x1F reflect the
EBU data
0 to 255
Default: 1
Teletext Data
Unit ID
Defines if there are EBU teletext
sub-lines included in the data.
Data Unit ID has range from 0 to 255. Values are:
? 2 = EBU teletext non-subtitle data is not
included (default).
? 3 = EBU teletext subtitle data is included.
Note: Data Unit ID must be set to 2 or 3 for
proper decoder operation.
