On the receiving side, the THC63LVD1024 LVDS-to-parallel bridge has two LVDS inputs and two parallel outputs. It can operate in four different modes:
Single-in, single-out: The first LVDS input receives the video stream, and the bridge outputs it on the first parallel output. The second LVDS input and the second parallel output are not used.
Single-in, dual-out: The first LVDS input receives the video stream, and the bridge splits even- and odd-numbered pixels and outputs them on the first and second parallel outputs. The second LVDS input is not used.
Dual-in, single-out: The two LVDS inputs are used in dual-link mode, and the bridge combines the even- and odd-numbered pixels and outputs them on the first parallel output. The second parallel output is not used.
Dual-in, dual-out: The two LVDS inputs are used in dual-link mode, and the bridge outputs the even- and odd-numbered pixels on the first parallel output.
and the second?
The operating mode is selected by two input pins of the bridge, which are connected to DIP switches on the development boards I use. The mode is thus fixed from a Linux point of view.
Can the state of these switches be read from software?
