Component Switching using Multiple Matrix Switchers
A commonly used video format is component video, and switching the three signals (components)
simultaneously is sometimes a complicated task. Using several
Matrix Switchers
, however, this can
be done very easily and efficiently. This is done by dedicating each switcher to a single component –
one for the Red component, one for Green, one for Blue, and one for Sync. Each component of the
RGBS signal is then connected to the
same
input (or output) number on the switcher. For example,
the first RGBS source is connected to Input #1 on the 4 switchers, the second is connected to Input #2
on the switchers, etc. The switchers are configured to mirror each other, so the input to output
connections are identical on all 4 machines!
In order to switch during the vertical interval when working in this way, the switchers should be
configured for operation using the “Ext. Sync”. A sync source should then be connected to all the
machines (for RGB this could be the Green channel, and for YUV this could be the Y channel).
The same principle may be used for YC (2 switchers), YUV (3 switchers), RGBS (4 switchers), and
RGBHV (5 switchers).
