2.2.4 Digital Video I/Os of the Atomix HDMI Board
This section contains some information about the digital video in- and
outputs of Atomix HDMI.
DVS usually names the input/output channels (connectors/ports) of
the digital video signals alphabetically: the main video stream is then
available, for instance, on port A and the secondary video stream on
port B. For YUV you normally require one link (connectors named ’A’,
single link). For YUVA you will need two links (’A’ for YUV and ’B’ for
the key signal). With RGB you will always need two links (’A’ and ’B’,
dual link). The same applies to transmitting rasters of a higher resolu-
tion such as 2K.
However, because Atomix HDMI provides two independent video
channels (different video rasters and color modes), the secondary
B ports can also be used for the second video channel. Then by default
YUV can be transmitted independently. By changing the speed of the
ports to 3-Gbit/s SDI dual-link connections can be realized. They pro-
vide all the features of a standard dual-link connection, but require only
one connector instead of two.
The following tables show the signal distribution over the I/O ports for
the different video rasters (color modes) when either one or two video
channels are configured for the board:
LEDs Indicate that the programmable chips (FPGAs)
are programmed. If both are illuminated, the
firmware is programmed and the board will op-
erate properly. If even one is extinguished, you
have to perform a firmware programming/up-
date (see section “Upgrading the Firmware” on
page 3-14).
