4.
Ensure that Teletext mode is set to off. Issue the front panel command
VBI>Teletext>Mode=Off or the remote VBI TELETEXT MODE OFF
command.
5.
Set the decoder VBI format control to automatically detect the type of VBI data to decode.
Issue the front panel command VBI>Format>VBI Format Cntrl=Auto or the remote
VBI CONTROL AUTO command.
6.
If your system requires you to manually set the type of VBI data to decode, follow these
steps:
a. Set the decoder VBI format control to manual. Issue the front panel command
VBI>Format>VBI Format Cntrl=Manual or the remote VBI CONTROL MANUAL
command.
b. Set the VBI format to Tiernan closed captions. Issue the front panel command
VBI>Format>VBI Format=Tiernan CC or the remote VBI FORMAT TIERNANCC
command.
B.1.3.3 DVB 4:2:2 Expanded Windows, 16-Line and 32-Line
Tiernan encoders and decoders support both 16- and 32-line expanded windows operations. As
with normal video encoding, the first 6 lines of the VBI region contain timing set-up information.
Expanded Windows use the remaining lines in the VBI region, either 16 or 32 per frame (8 or 16
per field), to transmit data.
DVB 4:2:2 Expanded Windows is supported on a composite analog or component digital (SDI)
format video signal. This standard supports both PAL/625 and NTSC/525 format video standards,
and can transmit any of the following VBI services:
PAL mode: Teletext, PDC, WSS, and VPS
NTSC mode: ATSC Closed Captions, V-Chip, AMOL I and II, and VITC
B.1.3.4 Operational Considerations
Ensure that both VBI teletext and closed captions are disable when either 16- or 32-line
expanded windows are enabled, as teletext and closed captions overwrite expanded windows
data.
Chroma must be set to 4:2:2 for proper expanded windows operations.
B.1.3.5 Hardware Requirements
The TDR60 decoder processes VBI data in its standard configuration.
B.1.3.6 End-to-End Configuration
To configure the encoder and decoder for DVB 4:2:2 Expanded Windows operation, follow these
steps:
