That rack display could be as simple as a sub 19" wide, computer monitor. There's also some smaller usb enabled
computer monitors out there I saw yesterday, that might be an option for a smaller 1080P screen.
You could run a htpc and use that digital movie poster display, if your av rack and digital movie poster display
are close together, right outside the theater. And that htpc could retire the Pioneer disc carousels.
I plan to host my media collection via CollectorZ, on my digital movie poster panel. (And I also plan for the
htpc to also handle a single upper mask, for the screen.)
