Very interesting question.
We have been discussing something along these lines for dual-projector 3D. What we are thinking is that one uses two Radiance units in series as you suggest. Then we allow output 2 to be the pass-through of the input (i.e. no processing at all) and output 1 is normal.
This allows several nice feature options:
- Pass-through mode. We have a "pass-through" mode on our feature list for the Radiance and this would allow us to check it off our list.
- Some high-end audio folks have asked me for a direct connect HDMI-in to HDMI-out for audio so that the original HDMI clock can be used for the HDMI output audio clock to (potentially) reduce audio clock jitter for improved audio. Not sure this is a real advantage, but I would be very interested in if people could notice a difference using the original HDMI input clock (pass-through mode) verses our generated output clock (normal mode).
For 3D, this allows us to have a 3D input mode that outputs 2D video. This has at least two applications I can think about.
1) Theater with a 3D projector and a 2D TV would use two Radiance units. The first outputs 2D to the AVR/2D-TV and passes the input to the second Radiance which outputs 3D. This also allow each (TV,projector) to be calibrated independently.
2) For dual-projector 3D, the first Radiance outputs "Left-eye" on Output1 and its pass-through on Output2 to the second Radiance. The second Radiance then outputs "right-eye" to the second projector.
For your suggested blend application, the first Radiance processes the source and does CMS to Output1 for the first projector, and its Output2 is set to pass the input directly without processing. Then the second Radiance takes the input processes it and does CMS for the second projector.
There are some details to consider - like each Radiance needs the same input configs - but these are managable.
I think your post was the final nudge we needed to raise the priority of this. I will put this as a priority right after 3D. We should have a Beta 3D release in August (I had thought July but the deinterlacing and reinterlacing work is not done yet). Then we can work on this.
