Dual mode with Quad-SDI input card, Quad analog input card and Streaming video card
When displaying the sources of one Quad-SDI input card, Quad analog input card or Streaming video card in dual
mode on different projection modules, some restrictions must be considered.
The four sources of the card are internally combined to two couples. The sources of channel A and channel B are
one couple and the sources of channel C and channel D are the other couple, please refer to the H
YDRA user’s
manual to identify the channels. When displaying such a couple on both modules – each channel on another
module – one channel will not be displayed correctly, when located on the same area on the respective modules.
Within the overlapping area the content of the video with the higher stacking order will be visible, please refer
to section
5.6.6 Stacking order of an object.
In the figure below video 1 has a higher stacking order, which means it is more on the top than video 2. There-
fore in the overlapping area the upper left corner of video 2 shows the lower right corner of video 1. Changing
the stacking order would show video 2 completely, but video 1 would show a part of video 2 in its lower right
corner.
