Mode function allows you to determine whether the teletext
data will be included in the video output stream. Unless On is
selected, teletext will not be included in the video output
stream. On, Off

VBI>Format: used to set the VBI parameters; for additional information on VBI, refer to the appendix on VBI data transmission.
VBI Format When VBI Fmt Cntrl is set to Auto, this parameter is query-
only; the TDR60 automatically detects and processes the
incoming VBI data.
When VBI Fmt Cntrl is set to Manual, this parameter is used
to set the type of VBI format to be decoded and included in
the video output stream.
■
Off – no VBI information will be included in the video
output stream
Note : VBI Fmt Cntrl must be set to manual for this
parameter to be set to off.
Note : To ensure proper display of teletext, VBI Format
