Daisy Chain Mode
Daisy chain mode refers to the way several multiviewer cards can be connected to one another, in order
to be able to configure a greater number of input streams.
Daisy Chain mode is applicable to the MGU, MGG and MNU modules only.
How to Connect Cards in Daisy Chain Mode
The multiviewer cards have to be connected using the cables provided specifically for this purpose.
The illustrations below show how the cables are connected in order to daisy chain different types of
cards in an SFR18 frame.
The internal video path consists of two UHD/4K (3840x2160 pixels) heads. If a source can be scaled and
positioned twice, as in the MGU200, each scaled and positioned image will be positioned on each head
independently. There is a scaler per input for head 1 and a scaler for head 2 in this case. Even though the
card has 8 SDI outputs and they can be used independently as 8 streams, the limitation remains that the
cores consists of two UHD heads.
