I will try to touch on the topics since my last posts.
In an attempt to simplify setup (and reduce my time on the phone helping setup), I asked Patrick to change the Global EDID to always report HDR/HLG/2020, and turn on HDR Mapping by default, in 122819. Unfortunately it looks like the TVs and projectors are ignoring the Rec 2020 flag (a major mistake in my opinion) and so do not go to Rec 2020 when the Pro output is set to SDR2020 automatically. So people were not actually getting Rec 2020 in the Projector/TV for HDR. Not good. Unfortunately it means my plans to reduce my support load are stymied. So back to default being HDR in gets you HDR out with Tone Mapping off. We will leave the HDR/HLG/2020 EDID flags enabled back to sources so a small victory for reduced setup time.
We will be adding a few more "direct codes" for me, and others, to help get setup quickly. More on this at a later date.
If you just received your unit it had older software due to an internal miss communication. One of our internal only tests was broken in 120419 and 121819. I asked out test person to just use 100619 for that test, and she thought I meant test and ship with 100619. Apologizes for this. We have addressed this and are now using 122819. There are improvements in 122819, so you may want to consider upgrading if you received your unit recently.
Here is a setup tip for the Harmony remote products. The correct way to select an input with a programmable remote is to send the "Input" code, and then the input number. Unfortunately Harmony did not include the "Input" button. If nothing is on the screen sending just the input number works, but if anything is on the screen and you send just a number it will not work and could possibly do something unwanted. The work around is to send a "CLR" code to clear any onscreen display first, and then the input digit. This is especially important after power-on since the OSD should the input on screen, requiring the Input command first, but the CLR command does the job by taking down the OSD so then just the input number is needed. As part of this, I tell my Harmony Elite "no input select needed to the Pro", but then I add both the CLR and input number as commands to achieve a source change. This saves the bit of time needed to send the number by itself and perhaps might prevent an unwanted option.
Someone asked if deinterlacing applied to 480p. It does not. Deinterlacing is for only interlaced sources. There are 480i60, 576i50, 1080i50, and 1080i60. Progressive sources (480p, 720p, 1080p, 2160p) do not need deinterlacing. The Pro does have a "re-interlace" feature mostly used in Europe. In Europe (and elsewhere) many settop boxes only did a vertical pixel replication for 576i to 576p, instead of deinterlacing. The Pro re-interlacing detects the fields, internally converts back to interlaced, and then does its own deinterlacing.
Someone noted my earlier posts on Pro deinterlacing versus the "Gennum" in 1080 Radiance products. The Gennum has a diagonal filter which is good for sports like hockey with a pronounced line in the middle. The Pro does not have a diagonal filter. I think the Pro has the advantage for HD content and likely non-sports SD content over the Gennum since thePro deinterlacing is designed to "comb" much less often. I very much dislike combing for deinterlacing, and so I prefer the Pro deinterlacing.
To repeat something in one of my recent posts: We recommend that the sources be set to output content at the native resolution for the content, including SD content. Then the Pro NoRing(TM) scales up to 4k.
When we mention the Pro accepts SD content, it means all SD content.
I mentioned a 2XXX unit scaling to 1080 before going into the Pro mostly for completeness. I am not recommending you run out an buy a 2143 for this. as the different would be small. The Pro does a very good job scaling SD to 4k, and improving this further is on our to-do list. Not sure when we could get to this though.
On the question of noise reduction and enhancements: We plan to add spacial image enhancement, and spacial noise reduction. We do not plan to add temporal noise reduction. Now that we have ADTM well in hand these are high priority, right behind our planned pipeline precision improvement taking the entire pipeline to at least 12 bits (current front end is 10-bit).
The Pro "outputs HDR in a SDR container." For this output mode, only the JVC (that I know of) works with the trick of setting the HDR Flag on even through the Pro is outputs in SDR mode. As mentioned you select a Gamma = 2.4 in the JVC projector for the memory you select with this (I use the "HDR" mode, with Gamma in the Projector = 2.2 since it measured closet to 2.4). This does not work with other products. For example teh Sony forces it HDR tone mapping on if the HDR flag is set. No way to turn off its tone mapping in this case and you do not want to tone map twice.
Lots of little details. Hopefully I got them all.
