6.3.1. Video crosspoint
The number of the inputs and the outputs are depending on the
number and the direction of the video modules. As MODEX
supports only one video transmission over the link, the link
appears as an input or as an output depending on the direction
of the extender.
At the transmitter side the link appears as an output. At the
receiver side the link appears as an input.
Example
The figure shows one input and one output. HDMI is the input port and the output port is
the fiber optical connector
– towards to the receiver. In this case there is no real crosspoint
switching, the signal of the input port is always switched to the output port (except if the
output is muted).
6.3.2. Audio crosspoint
MODEX extenders support two audio groups: the Main audio group and the S/PDIF audio
group. These groups are independent from each other. In this case there are forbidden
crosspoint connections. The link can support four audio layers:
Main audio group:
Embedded audio (from transmitter to receiver)
Return AUX (from receiver to transmitter)
S/PDIF audio group:
Forward Audio (from transmitter to receiver)
Return Audio (from receiver to transmitter)
At the transmitter side the Embedded audio and the Forward Audio appears as an output,
the Return Audio and the Return AUX appears as an input. At the receiver side the direction
is the opposite.
Figure 6-1. Audio layers
The four audio layers, between the transmitter and the receiver are defined and fixed,
always extended. The other audio inputs and outputs are optional and depend on the
installed interface modules; the available crosspoint settings depend on the application
mode set in the properties of the audio module.
