Configuration

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 on page 15

).

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).

Video Processing Adjustments

The controls for video processing on each channel are the following:

Test signal generator – when enable, sends the internal test signal gen-
erator 75% Color Bars test signal to the channel output.

Note

When the internally generated color bars test signal output is enabled, the rel-
ative sync and burst may be offset in relation to the input SDI stream timing.

EDH Insertion – insertion of new EDH can be enabled or disabled
(input EDH is always removed).

HANC – horizontal ancillary data (including embedded audio) may be
passed or blanked.

Reference Input Sync

The module is locked to the reference input sync. The following reference
input sync considerations should be noted:

Jitter performance of the module is influenced by the time base jitter of
the reference input sync.
