can be realized. They provide all the features of a standard dual-link
connection, but require only one connector instead of two.
Video channel 1 and, if available, video channel 3 can also be switched
to a standard dual-link connection. Then, the second video channels of
the video channel pairs 1/2 and 3/4 (i.e. channels 2 and 4) will not be
available and their SDI ports have to be used for the secondary video
signal (link B).
The following tables show the signal distribution over the I/O ports for
the different video rasters (color modes) when either SDTV or a
1.5-Gbit/s connection are configured for the channels, or the channels
are set to 3 Gbit/s:
HDMI output
VENICE 2U: You can select the HDMI port(s) (optional) of VENICE 2U
by setting the output priority in the software to ’DVI’ and then selecting
the raster.
The first and, if available, the third HDMI port of VENICE 2U (i.e. video
channels 1 and 3, ports labelled ’HDMI 1’ and ’HDMI 3’) are
