Line pairs in the P_Active line category can be reserved for carrying data
by configuring Data Line Pairs with local or remote controls. Refer to
Table 4 for a listing of the Data Line Pairs lines that are available with each
setting.
Programmable VBI and Active Picture Lines
The programmable lines in the vertical blanking interval include the con-
figurable VBI lines (CVBI). Configurable active picture lines (P_Active) can
be reserved for carrying data (refer to
Table 4 ).
These line pairs can be configured for the following:
• Blank – in local mode, select On to blank all lines of CVBI or Off to not
blank. In remote mode, lines can be blanked or passed on a line-by-line
basis with the web page (toothed blanking).
• VBI Setup – in 525 mode, a control is provided for turning VBI setup on
or off. This is a global control that affects all lines of VBI.
Note For this control to be active, the Active Video Setup control on the composite
output must be set to on.
