I got the design to compile, 2 HDMI inputs (unnesseserally using 2 full
decoders), switched to 1 output (the encoder also is not needed if just
passing through the input data). So the next step is to drastically
reduce the whole design to the essentials: no S/PDIF, no external RAM,
smaller (2 channel) buck regulator. That will result in a very cheap, (2
layer,) fully independant (2 input) ambilight control!
I will name that pandaLight light or whatever and use the LX45 design
solely for the more complex video computation it was originally intended
for!
