Grouping Pattern Examples

For switching purposes, connectors can be grouped in two basic patterns of virtual channels, spanning
and sequential. Explanations and examples of each follow.
Spanning Grouping Pattern
A spanning pattern is the most common method of grouping connectors for an Optima Distribution
Matrix. When this pattern is selected, each of the component (standard) signals in an aggregate signal is
assigned to a connector on an adjacent board. The same pattern is then repeated for the outputs.
Example
In the Y/c system in FIG. 20, the "Y" component is assigned to the input connectors on the first board
and the "c" component to input connectors on the second board. The pattern is repeated for the output
connectors. The stereo audio signal is assigned to the input and output connectors on the stereo audio
board. The first input channel of VM 0 (audio-follow-video) includes both components of the Y/c signal
(the first input connector on each video board), plus the stereo audio signal (the first input connector on
the stereo board).
When you switch Input 1 on VM 0, the Y/c and stereo audio signals are routed simultaneously. On
VM 0, any of the grouped Y/c input channels and their corresponding stereo pair input channel could be
routed to any or all of the twenty available corresponding output channels.
Video and audio breakaway signals can also be routed by using virtual matrices that are configured to do
so. In the example below, when you switch Input 1 on VM 1, the Y/c signal is routed. When you switch
Input 1 on VM 2, the stereo audio signal is routed.
