XA2: Disappointing firmware control of the Reon Vx processor

Thread Starter 
I'm going to run tests tomorrow but I found the user controls of the Reon processor to be very limited--and in my opinion poor.

I've attached the page from the user manual that shows what control you have over the Reon. (I apologize for having to send the image rotated but the dumb bb software when checking the limits of image size thinks there's a difference between 800x640 and 640x800.

Anyway-- here's all that has been implemented:

HQV Color Spectrum Control -- I guess this is what Toshiba calls "Selective Color Enhancement. Select from -7 to +7

HQV SD/HD Detail Enhancement - this is what Toshiba calls "Edge Enhancement" -- no real scale here like in a video processor -- just 3 settings -- Off, Low, and High. Come on Toshiba-- give us 0-10 at least.

HQV SD Random Noise Reduction-- this is what Toshiba calls "Random NR" and is only available for SD. This time just 2 settings - On/Off.

HQV SD Mosquito Noise Reduction - this is what Toshiba calls "Mosquito NR" and again is only for SD since its for MPEG files. And again only On/Off.

HQV SD Block Noise Reduction - this is what Toshiba calls "Block NR" and again is only for SD since its also an MPEG problem. And again only On/Off.

I guess I'm used to having an external video processor with much better firmware controls of the features.

However, Robert of VE-- can you ask your contacts at Toshiba to consider giving us some gradient scales for these features-- from 0-10 at least in a future firmware release????????????

Interestingly, I have generally found the less you tinker with these adjustments the better off you are (with any player). I'd really want to see the film just as it's read off the disk. I think adjustments like you describe are, for the most part, better done by the display. And edge enhancement? No thanks!! That's what plagued DVD for so many years...the less the better.

I agree with Ken - I have no interest in further processing the picture.

I can tell you that the mosquito NR feature on the XA2 does AMAZING things for the noisy sample scenes on the HQV test disc. You definitely would want this turned on for some discs. The cool thing is that you can save three different presets with different combinations of settings, and you can instantaneously see the result as you change presets or toggle the different types of noise reduction on and off.

I won't use any of these options either. I may play a little with the edge enhancement but that's about it...

What's also worrying me is that the A2 supports 480i out over HDMI while the XA2 does not (as far as I understand it). Why is that? Generally I think the XA2 should have 2 resolution settings: One for SD and one for HD. I'd configure it like this:

SD: 480i/576i out.
HD: 1080p24 out.

Alternatively Toshiba could also offer a "pure direct" output mode which would always output the original video format without any conversion (neither deinterlacing nor scaling nor anything else). That's what Pioneer is offering. And it does make sense if you have an external video processor. The Reon might be a great chip, but that should not make Toshiba think that nobody will ever have an even better video processing chip elsewhere in the video processing chain (e.g. in the display/projector).

My Mitsubishi HC 5000 1080p projector also has the Reon VX chip. Those noise reduction features mentioned here seems to be adjustable from 0-15 on the Mitsu, from the manual:

TRNR 0 - 15 Use to reduce random noise. (See page 32.)
MNR 0 - 15 Use to reduce mosquito noise. (See page 32.)
BAR ON/OFF Use to reduce block noise. (See page 32.)

And on page 32:

This projector has the following noise reduction functions. However, these functions don't work with 720p, 1080i, and
1080p signals and signals supplied from computer.

I am looking forward to the reports of the SD scaling, particularly from those who have the Crystallio. If the processing in the XA2 is as good as, or better than the C2, then I don't see a need anymore for 480i out via HDMI.

Should be interesting indeed.

IMHO that's short sighted. Do you think the C2 is the "end it all" solution and there will never be a chip/VP which can deinteracle & scale better than the C2?

Lack of 480i HDMI output really seems like a blast from the past... Especially considering my Lumagen Radiance preorder.
