The HDR Intensity Mapping, formerly Shaping LUT, adapts the intensity transfer function of an HDR source for display on either an HDR TV/projector, or a SDR TV/projector, with a different maximum brightness than the source mastering level.
This works whether the 3D LUT calibration has been completed or not (but of course it works better if it has).
New Lumagen Radiance Pro Series
We expect that some aspects of HDMI 2.1 will be able to be added with a software upgrade. One example is Dynamic HDR Info Frames. While we cannot commit to this until we have it implemented, it looks like the current hardware will be able to support this feature.
The current Radiance Pro hardware platforms are 4k60. So 8k support, for these models, is not in the plans at this time. That said, the Radiance Pro 444X *may* at some point be able to support 8k output, either by left/right dual output using 18 GHz outputs, or potentially a 36 GHz output card upgrade. This is possible since the 444X models were designed with four 9 GHz outputs which can, potentially, be combined into a single 36 GHz output due to the modular I/O architecture.
Next question is input at 8k. Since there are four times as many pixels to process, there is not enough memory bandwidth or gates in the FPGA and a new design is needed.
I believe 8k output is more important than 8k input and so the potential for 8k output IMO could extend the life of the 444X models if we do end up supporting it.
