Anyone else see an issue with post numbers in this thread... Before I posted this there is a link for page 9 but no page 9. After I post this I expect to see this is post #241 of 242, but there will be no post 242. Oh well...


Edit: Hmmm - maybe this post fixed it

Anyone else experienced this?
This hasn't been reported by anyone else AFAIK. Try unplugging-not just turning off-the Radiance for 30 seconds or so, then plugging it back in. If this doesn't work, you can try temporarily resetting the Radiance to factory defaults (don't save before shutting down). If still bad, try reinstalling the firmware. If the problem is still there, try dropping back to the previous firmware version and see if the problem goes away.

LUMAGEN 2143 + DATASAT RS20i I/O question

Guys,,

I about to install the LUMAGEN 2143 + DATASTA RS20i for my system , just checking in to see how everyone routes their HDMI ?

I assume all the source are routed to the 2143 , then OUTPUT 1 -> Projector Input,
However what happens to the SOUND? Do we just use the TOSLINK + the COAX on the RS20i ?

I am worried that not going through the HDMI as sound input on the RS20i will not let me get the best possible sound out of my equipments

Is that going to be the case?

HELP ~~~~~

Here is a sysnopsys of an email I sent to 911turbojk:

Sources to Radiance. Radiance Output 1 to Datasat. Radiance Output 2 to projector.

The Radiance will pass audio, including HD audio, to Datasat.

Lumagen Announces the Radiance 2020 Video Procesor

Today Lumagen is annoucing the Radiance 2020 video processor. The Radiance 2020 is essentially the (now retired) Radiance 2021, minus the COAX audio output and in a smaller case.

It has exactly the same video setup, processing and calibration feature set as the Radiance 2021.

Highlights:
4 HDMI 1.4a inputs (max 1080p60)
2 HDMI 1.4a outputs (max 1080p60)
9x9x9 Linear-Gamma RGB CMS
Darbee DVP(TM) enhancement
Image-based auto input aspect selection
RS232 command port
Wired IR command input
12 VDC power supply
Case: 11 x 1.7 x 5 inches

Note that the Radiance 2020 is not rack mountable.

The US retail price for the Radiance 2020 is $2495. Volume shipments for the Radiance 2020 will begin on 10/28

Seem to be a very good replacement for the mini.

Does Lumagen still plan to introduce this year a new 4k processor with a full HDMI 2.0 in and out?

RickAVManiac and everyone:

We are obviously working on a Video Processor that will accept 4k inputs. However, currently we do not have anything to share on this product other than we are adding to our "Beta Site" list.

If you are interested in either being an "Early Beta Site" (limited), or "Beta Site" (a much larger group), please email us at support@lumagen.com with your contact info.

@jrp

Can you give a rundown on the 3 noise reduction settings? What particular noise patterns are each designed for and some idea of how the numerical scale relates to strength of the noise suppression. Any suggestions on using typical sources to test settings would be appreciated as well.

Zoyd:

I don't have a lot to say on the range of enhancement settings, other then stay away from the maximum end of the range. The best setting is really a personal preference, but I can give you some starting points.

For 2D/3D Noise Reduction: I use 3 since I see a slight improvement without artifacts. For Noise Reduction, we believe it is "temporal" up to about 3, and then the "spacial" noise reduction starts to kick in. We don't know the exact point where spacial kicks in since the manufacturer has never told us. Temporal noise reduction should not affect resolution much, but spacial noise reduction will. I think the optimal range is 3 to perhaps as high as 6, with 6 starting to show some resolution reduction.

For Mosquito Noise Reduction: I use 3, and think 3 to 6 is also a good range to try.

Block Artifact Reduction: I leave this set to 0. This control is to improve horrible video quality. Don't watch horrible quality video sources.

Sharpness: I use all six settings at 3. I think the reasonable range is 3 to 6, but have heard some people using up to 10. You may start seeing some artifacts as you get to 5 and above.

Dynamic Contrast: I don't like any "dynamic" controls like this. I leave mine set to 0. Often using a slightly higher Gamma will give similar results without the chance of causing artifacts. Whether it is a Dynamic Iris, or a Dynamic Contrast, they use an area based algorithm that can, and will in some cases, be fooled into doing the wrong thing. First rule would be to not use both a Dynamic Iris and Dynamic Contrast, as they are trying to do basically the same thing and they can interfere with each other.

If you want one of these, first try the Dynamic Iris if your projector has one. I suggest you try it at a low setting. If not, or you have a TV, and you want to test Dynamic Contrast try setting it to 1 or 2. If you have a Radiance that includes Darbee DVP(TM), I suggest that the Dynamic Contrast be set at 0 and use the Darbee feature - which is similar to a "special twist on local area dynamic contrast" control, and works much better than a large-area based Dynamic Iris, or Dynamic Contrast.

Radiance 2020 CIH and audio routing

I posted a question in the CIH section and rather than double post, included a link below:

Can the JVC RS-56 zoom method be improved with Radiance?

A second question is about recommendations' for cable routing. My configuration is fairly simple and my plan is:

Comcast set top box HDMI to Radiance Input 1. Radiance HDMI out 1 to Receiver SAT/Cable HDMI in. Radiance HDMI out 2 to JVC RS-56.

Oppo BDP-103 HDMI out 1 to Radiance HDMI input 2. Oppo HDMI 2 to Receiver HDMI BD input. Radiance HDMI out 2 to JVC RS-56.

I suppose I could use a single HDMI out from the Oppo and not mess with changing receiver audio inputs but like the idea and confirmation of the receiver source display.

Thanks.

yes. The mini has a 125 point CMS and the fpga resources are now pretty much full up. The2020 has he much larger 729 point LUT CMS and more memory and larger FPGA on board so it may get further enhancements that the mini would not have capacity for.

There is helpful to check the 3D Cube Resolution Comparison Guide where you can visualize the difference of calibrated color points precision over various cube resolution sizes between all available hardware solutions of pro industry & consumer market.

You can check also the 3D LUT Boxes / Video Processors Comparison Table Page which features the complete spec. list of the available hardware solutions.

These comparison screens shows only the device features that are useful or can be used for HT use only (HDMI In-Out).

Wouldn't it be best to go for a eecolorbox if I wouldn't mind skipping 3D or what is the catch here?

Hi, I posted the above example to show the differences of specs or cube sizes visually. If you want to find or discus information about other video processors or 3D LUT boxes, you can use other threads at display calibration area of this forum.

It's better to discus here only Lumagen related stuff, thanks.

The Radiance is a complete scaling and calibration solution, while the eecolorbox is a LUT holder only. The 2020 also has Darbee functionality built in.

The Mini also has a much smaller form factor than the 2020. This could result in heat related issues with the Mini vs the 2020 when driving the processor hard (scaling + interlacing/deinterlacing + CMS + grayscale, etc).

I have only ever come across a couple of problems where heat may have been an issue with a mini installation. In those cases the unit was located in a non optimal location and was not installed vertically as it is designed to be used. In such an installation the use of an additional heatsink would likely solve any issue...and in any case, it is extremely rare.

Hi, Gordon. In no way was my post meant as a slap at Lumagen. I have a Mini that had some intermittent image instability problems when viewing 3D content, and it was suggested by the guys at Lumagen that they could have been heat-related. Although not mounted vertically, my Mini was in the open on top of a cabinet. I had also attached four standoffs to its base to allow airflow around all its surfaces. It was replaced in that installation by a 2021 which has never shown any trace of instability, and I now have a 2020 enroute to replace the Mini in its second installation (where it is now exhibiting video and audio dropouts).

I'm a new 2020 owner and I calibrated and got it set up yesterday. My chain now is Oppo 103 (HDMI 2 output and source direct) > Marantz SR7008 AVR (processing is turned off) > 2020 > display. Both the 103 and the 2020 are set to Ycbcr 422 now. I've also tested their other color spaces. Checking with Spears and Munsil it fails horizontal chroma burst, has banding in the ramps, and the chroma range boxes aren't visible with the Oppo set to 422 and 444. It passes the chroma burst on RGB but banding is still there and the boxes aren't visible. Changing the 2020's output doesn't make a difference. Before I added the 2020 to the chain, it passed everything on 444 but 422 failed.

Should I be concerned about this?

The Spears and Muncil Chroma Burst is different than actual video in two regards:

1) The Spears and Muncil Chroma burst uses out-of-Nyquist-band transitions. This is actually common in test patterns. However, actual video is required to keep transitions within the frequency limits imposed by Nyquist Sampling Theory. Within the Radiance the input pipeline is 4:2:2, and the calibration pipeline is RGB (i.e. converted to full resolution Chroma, and then to RGB), and this is done with a Nyquist filter. Nyquist filters cannot pass out-of-Nyquist-band signals without changing them.

2) The Spears and Muncil Chroma burst uses YCbCr combinations that create out-of-range values when converted to RGB, as the Radiance does in its calibration pipeline. The RGB values in the Radiance clamp negative values to 0 and over-range vales to 255 (speaking in 8 bit terms). Since black = 16 and white = 235 in 8-bits terms the RGB values must be significantly below black or above white to get clamped. The Spears and Muncil Chroma Burst pattern has values that do get clamped (both negative and over 255). So once these are converted back to YCbCr the values will be changed, and this will affect results when the data is then filtered using Nyquist based sampling.

So, are the Spears and Muncil Chroma Bust pattern useful? Certainly. We are glad to have it and the other patterns.

However, one must, as is always true for test patterns, understand what they are and how they should be evaluated. For example, the patterns can be good at checking TV/projector performance, but they do have limitations when used to evaluate a product that processes video, and this may include the processing in the TV/Projector if enabled. In fact the TV/projector processing may reduce bandwidth slightly in a non-visible way, but when put in series with another processor (e.g. Radiance), which also filters the video, the sequential effect of two filters may be visible.

Note that we did evaluate the patterns and were able to use the results to improve our performance when processing the patterns. These changes also improved our performance with actual video as well. We also found that the GF9450 video deinterlacing chip used in the current Radiance units has a very slight roll-off in Chroma bandwidth. So they are certainly helpful to us at Lumagen.

I have emailed Stacey (Spears) about my concerns that the patterns are being used by many who do not understand limitations of Nyquist Sampling and RGB clamping, and their effect on video processing. If Stacey is reading this he may even want to comment.

=================

Note on Radiance setup: If you have a progressive source (e.g. Bluray movies), you can put the Radiance in "Game Mode" to bypass the GF9450 for that source (in Input Video Setup menu), assuming you are not using any GF9450 enhancements (e.g. edge, noise). I do not think that for real video you will see any improvement in Chroma bandwidth, but it is possible there might be a very slight improvement, and it will improve the Chroma Burst pattern. It also has the potentially nice side effect of reducing the video latency in the Radiance since it eliminates the GF9450 processing time.

^ Thank you for the explanation. I had no idea about how the Lumagen's processing interacts with the patterns. It's only the patterns I've seen issues on anyways. The PQ looks amazing with real material. The Lumagen has made a big improvement on my setup for calibration and processing.
