Hi Terry,
My difficulty is in thinking about the instant in time captured in the picture above. I'm quite happy that the Aurora can generate a sequence of RGB frames each reproducing the appropriate luminance for each colour but let us suppose that our B&W screen is displaying the red image and that the receiver filter wheel above has its red filter covering the area below the arc. The next filter will be green and so the area above the arc will be displayed to the viewer through a green filter even though they are still looking at a red frame.
This presents no problem when the luminance information comes from a camera whose filter wheel is precisely in phase with that in the receiver because the transmitted frame in the instant captured above will contain information appropriate to parts of both green above and red below the arc separating the two colour filters simultaneously.
As it happens, I suspect my interest in this is now purely academic. I had mistakenly assumed that the Multi-standard hardware was the same as that for the CBS Color Converter and that the only difference was a firmware change but I see now that they use different Xilinx chips so I assume that the CBS Color will probably not be available to me.
Peter.
