Input Clocking
The Input Clocking tab is used for assigning video input clocking sources to
input audio channels. The first column on the left side of the dialog box displays
the disk recorder channel numbers. The last column shows the audio clock
reference source selection (Figure 39).
You get one system reference by default from the Reference Genlock boards,
and up to four video input references, depending on which video boards are
installed in your Profile unit. Even if more than four video references are
available, only the first four input clocking references are used. If you look at
the bottom of the Configuration Manger window, you will see a graphic
representation of the installed boards. A key to the board representations is
shown in Table 3.
The video references shown in the Input Clocking tab—Video Input 1–4 —
correspond to the actual video boards installed, from left to right, as represented
at the bottom of the Configuration Manager window.
For example, a system that does not use all four available clock references
might be configured like this. In this specific example, shown in Table 4, you
have one analog composite board and one component analog board. The panel
in the tab shows System, Video Input 1, and Video Input 2.
