Official RadianceXD support thread - Page 40

Yeah, I'm kind of the same myself...I imagine that the all in one box might have some advantages (such as handshaking perhaps and possibly the ability to have different Darbee settings for different memories/resolutions) but not enough to justify me upgrading at the moment.

I wonder where the Darbee is in the chain? I've found that I get a better result having the Darbee after my Mini3D especially for A Lens use, since the Darbee is fed with a vertically stretched 1920 x 1080 signal. If I put it before the Mini3D then the Darbee effect is vertically stretched (and has fewer pixels to work on in the first place). A small difference, but then we're all looking for those small differences anyway.

Don't use an A lens, but I also (and I think most people) have the Darblet after the RadMini.    I have the RadMini on a short HDMI right after my AVR, then a 25ft HDMI to the Darblet, with a short HDMI to the projector.

Correct. All in one box allows you to adjust the Darbee for each input as with all other adjustments.

Normally it's placed as the last item before the display as you've mentioned.

For the Radiance 2021, the Darbee Visual Presence is after the Radiance No-Ring(TM) scaler, and so is at the output resolution. So from a processing point of view it is the same as having a Darblet following a RadianceXS.

Good to hear that I'm doing it the same way as Lumagen. It doesn't sound like I'm missing out apart from not having the flexible control of the DVP (though it's only a remote control away and I tend to leave it at 50% HD or OFF depending on the film/grain). Knowing Lumagen they won't leave us owners of older gear out in the cold when it comes to updates judging by past experience when I owned a HDQ.

Beyond the addition of Darbee and the lack of any analog inputs, are there any other differences between the new 2021 and the Radiance XS?

Those are the major differences. Here are the other things that are different (minor to most people):

- The Radiance 2012 uses a 12VDC power supply like the XE instead of a 5VDC.
- One RS232 control/update port instead of separate command out/command in RS232 ports.
- Internally it has a different FPGA (Altera Stratix III at 65nm instead of the older Altera Cyclone II at 90nm) since the one used for the current Mini/XS/XD/XE products did not have room to fit the Darbee stuff.

To quote the press release on the new FPGA:

I'm curious if the Radiance 2021 with the upgraded FPGA + Darblet processing has more "room" left over than the Radiance XS with the lower end FPGA without the Darblet processing. Meaning, I wonder which is more upgradeable.

The FPGA in the Radiance 2021 is shiny silver while the one in the XS is boring black.

Thanks. I think I'll sit comfortably with my XS and standalone Darblet until Lumagen's inevitable 4k processor.

I hope the next Lumagen release will have IP control... please...

And use IP for firmware updates! Not many components in my stack without an Ethernet connection... SJ

I agree.
We've gotten used to blu ray (etc) updates via Ethernet.

New ChromaPure 2.4 will allow setups for Select Colour Format and Colour Resolution for a Duo, but won't allow any selections when the Radiance is selected. Anyone else run into this problem?

Tom Huffman states that these 2 selections are not available for the Radiance. But, I can't get the Patterns to come up in the new ChromaPure 2.4 when the Lumagen is selected, despite following his Video Instructions on his web site. When the Duo is selected, and the selections put in, then there's a reaction from Radiance. Finally went back to my Calman where everything worked OK.

Problem solved: because I go between 4 different TVs here to calibrate, 1 with the Radiance XE-3D, and the other 3 with iScan Duos, to keep everything on par, the Laptop Serial Port is set to 19200. No problems with Calman, but ChromaPure has to have the Serial Port at 9600. Then it works. Setting the Laptop to 19200, and the Lumagen in ChromaPure to 19200, results only in a secondary flicker, but no Patterns. Set both back to 9600, then the Patterns come up. Probably that's why the Duo got a responce with the Radiance because then the 19200s matched.

Problem solved again! Unmounted my i1Pro off the TriPod , remounted my Spectracal C6 and profiled from the i1Pro, and now use Calman 5.1. AutoCal is included, any Meter Make and Model listed can be used, and DDC is in +/- .1 increments, rather than +/- .5 increments, then manually write in any values inbetween. Like cutting down a tree with either a hatchet, or go with the chainsaw.

New release 040213 posted. We do have one report of an audio issue coming with this release. If you load it, please let us know how it works for you.

Release notes:
Production 040213- Fix for YCbCr (422 or 444) output precision issue. Improved scaling. Fix for video momentarily blanking output with 3D video from some sources. Fix for interlaced vrate calcualtion in custom timing menu. Some other small fixes.

Installed new firmware on XS. Works fine, though there is a longer delay in getting sound output from system when switching channels on the Tivo or other input switching. Anything in particular that we should be looking/hearing from the new firmware?

Glad to hear it is working for you.

Audio should of course sound the same. There were some changes to the HDMI interface chip software with the intent of making switching is more robust for under-designed HDMI devices, and with dealing with the changes needed for the new chips used in the 2021. This may have made it slightly slower when changing/switching audio. We are planning to spend some time looking at speeding up audio (and video) switching times, but with the GF9450 in the design we are limited by it's design as to how fast we can switch and keep the GF9450 from locking up.

The video fix for 4:2:2 and 4:4:4 output is a fix for a very small math error in the output color space conversion. You can see the improvement in a ramp pattern, and potentially as reduced noise at near black.

The NoRing(TM) scaling had an improvement for the vertical NoRing characteristics to fix a small bug. While we were at it we also made a slight improvement for high-frequencies in the image.

So are the older units going to be limited by the newer unit's switching speed? It sure seems slower than it used to be for resyncing video (Longer blanking times). I hate for it to get longer.

I believe the slightly slower speed is pretty much exclusively due to making it more robust with some HDMI devices for the current units and not due to integrating the 2021 code into the code base. The new 2021 code is mostly "if-def'd" and compiled only for the 2021 updates. So, I was thinking the 2021 integration was more related to the new audio drop outs reported, not switching speed. Sorry this was not clear in my post.

Thanks Jim. On the subject of screen blanking, one thing I notice is when changing resolution (e.g. switching channels on a Tivo set to pass through) I get a glimpse of the new resolution image, maybe a frame or a few, then the blanking. It's as if it had the image, then it blanked. Curiosity makes me wonder what would be seen if there was no blanking. Does it get the image then lose it then sync and return it?

Can't (don't want to) to set the Tivo to a set resolution because then it's scaling. But I'd like to workaround the blanking to the extent possible. I don't have audio running through my Radiance FWIW.

GetGray:

Patrick and I have discussed this effect. You are seeing the image before the HDMI restart on the change begins.

The issue with fast switching is there are a number of products that lock up until power is removed when the HDMI video or audio changes (an interruption counts) unless there is an HDMI restart. It may possible to have a user selected mode that would allow the HDMI sinks (display or receiver) to take the change without the Radiance having to do a restart. This is not as simple as it seems and the GF9450 in the Radiance may need to be restarted with the audio/video change even if the display/receiver did not need a restart.

With work we might be able to come up such a user selected mode and this is under consideration. We do plan to work on speeding up switching, but not sure if this big of a change will be doable since there are probably a number unexpected side effects to deal with.

You guys are awesome. Of course you knew I thought that already. What other company listens and cares for the customer like you do? I don't know one. Thanks for the consideration. I'm happy to be a guinea pig if you need any help .

Thanks, Scott

Note to those who use the Composite Input on the Lumagen: Don't Upgrade to the New FW. Bug causing Composite not to Output. Jim's working on a new FW update to fix problem.

Composite?? I forgot it had it. My curiosity gets the best of me. What are you feeding via composite? On one hand $4k VP and composite don't appear to be a expected relationship. Then again, if I had to use it, I can't think of a better thing to put it through I guess

Some of us still have legacy analog sources such as Laserdisc in our systems. Not that I put my LD player to much use these days, of course, but I like knowing that I could if I needed to.

LOL, fair enough. I"m a video snob now I guess. Hurts my eyes to watch 480

Blame DishNet! Their Dual Tuner Receivers - One HD one SD Outputs. Wife watches HD on her Bedroom TV, and SD when she's ironing in my room watching `Her' DishNet Programs. Me, I watch Doctor Who HD on the DirecTV Receiver - HD not available on Dish. Elsewise OASIS Channel on ExpressVU. (And her NetFlix `has to be available' in every room she watches!)

New FW update 040513 now available that fixes the Composite Output problem. (Possibly another out in the next little while.)
