New Net City, YPbPr to RGBHV VGA Transcoder, which one ?

Post by akumajo »

Hi,

I know that this question was asked x10000000 but maybe that there is something new on the current market.

I'm currently using an XRGB-3 as a transcoder (B1 mode, LPF Off) on my New Net City.

Here's what I'm looking for :
1) XRGB-3 is an overkill only for this job (but hey, I have no use of my XRGB-3)
2) I need something "smaller" (a pcb is ok) and "plug and play" (just like a sync strike or an slg 3000, I love you bencao 8) )
3) of course it must have good quality
4) no input lag (beware, I have Leo Input Lag Tester :mrgreen: )

My champions are :
- Mayflash YPbPr to RGBHV VGA : http://www.mayflash.com/?Products/VIDEO ... GA001.html
Image

- Lenkeng (LKV7600) : http://www.lenkeng.hk/Html/Product/comp ... erter.html
Image

- insert your champion :wink:
Image

I'm very curious to know about the Mayflash, many arcade players seems to use it.

PS : dont tell me Burosch Con-1 unless you are selling it to me :mrgreen: , dont tell me an XSELECT-D4 cause I already have one and it's too big + overkill ;)

XSELECT-D4. It is the best that I've used and best as far as I know. You say dont suggest it because its too big? The thing is tiny.

Well I need to save space in my cabinet :). I try to save space when possible.

Also, my lovely XSELECT-D4 is already in other setup and will stay there.

These units are another option for transcoding -> http://www.ebay.co.uk/itm/HD-Component- ... 483699f825

looks good too, are you using it ?

I would like to hear about arcade cabinet players, what are you using guys ?

ah someone need to review all those transcoders just likes Fudoh and videoprocessors ^^

Unfortunately I have no real reason to transcode from component to dsub15 on my tri-sync Naomi's. I don't use enough 480p software from consoles to warrant any "special" device, over and above the multitude of scaler/transcoder units I already have.

Sorry.

I would say that it hardly matters for 480p usage. Just buy what you can find. The Neoya X2VGA boxes are pretty neat. So are the ones from Audio Authority. On the HDBox clones I found scanlines on the output to be lightly misaligned, while the PSP to VGA converter/scaler box was fine in this regard.

Fudoh, how do you rate your "reference studio quality" transcoders ?

Can you suggest a benchmark ?

It's just an bandwidth issue. In theory the quality could degrade the higher the resolutions gets. With a PS2 you get quality 100% on par with the DC VGA box. Cube and Wii suffer from "not so perfect" component signals in the first place. When Lawrence reviewed the XSelect-D4 I think he mentioned that he came from an Audio Authority converter and like the D4 better, but I can hardly imagine that the difference was big.

I see, well it make sense. Some numbers ...

Xselect-D4 : Max Resolution (1080i) / Bandwitdh (??? Mhz)
XRGB-3 (B1) : Max Resolution (1080i) / Bandwitdh (??? Mhz)
Ebay HD Component Video to VGA RGBHV Format Converter (black box) : Max Resolution (1080i) / Bandwitdh (110 Mhz)
LKV7600 Component Video to VGA Converter : Max Resolution (1080p) / Bandwitdh (??? Mhz)
HDBOX PRO : Max Resolution (1080p) / Bandwitdh (??? Mhz)
Burosch CON-1 : Max Resolution (???) / Bandwitdh (??? Mhz)
Crescendo RTC2000 : Max Resolution (1080i) / Bandwitdh (130 Mhz)
Crescendo RTC2200 : Max Resolution (1080p) / Bandwitdh (??? Mhz)
Audio Authority 9A60 : Max Resolution (1080i) / Bandwitdh (250 Mhz)
Audio Authority 9A60A : Max Resolution (1080p) / Bandwitdh (250 Mhz)
DataPro VD-Z3 : Max Resolution (1080i) / Bandwitdh (145 Mhz)
DataPro CSV-955A (Mayflash YPbPr to RGBHV VGA seems to be a clone/rebrand, also this is an upgrade of VD-Z3) : Max Resolution (1080p) / Bandwitdh (? Mhz)
Neoya X2VGA2 : Max Resolution (1080p) / Bandwitdh (? Mhz)

Personally (for what it's worth) I wouldn't be worrying too much about benchmarks..... especially going into an arcade cab screen.

For arcade you are probably right, anything @480p should be enough.
But since I have compiled a few things, it could be usefull in futur for console needs.

In theory there's one aspect which is much more important than bandwidth. It's the question if the transcoder in question does output a clean "G" signal or not. The Con-1 for example does not. It does include full sync with the green signal in addition to the H/V syncs available. This can cause problems on various displays. The Con-1 for example doesn't work on the Pioneer PDP in RGBHV mode, but only in RGsB mode.

The Crescendo on the other hand does output real clean sync. A RGsB signal in a RGBHV connection can also cause a green tint, even if H/V sync are used.

Which one will you get ? If you're looking for something cheap and easily available, try the PSP VGA upscaler from Lenkeng.

Does anyone know if this cable can works ? So a transcoder is not needed.

I have to give a recommendation for Crescendo Systems. Their quality is second to none, as is their support. You're dealing directly with a very knowledgeable enthusiast who designs, builds, services, and answers emails about these things himself. You're not going to get that anywhere else.

I was doing some modding on my TC1600. I got impatient, tried something I knew was a bad idea, and fried something in the vertical sync circuit. I emailed Kim and told him honestly what happened. He could have justifiably said, "you shouldn't have had it open, you broke the warranty, you broke the unit, **** yourself!" Instead, he fixed it free of charge, and gave me more tips for working on it (wasn't the first time). He'll certainly have my continued business.

Yeah Crescendo is good stuff but overkill for my need. I asked mayflash support about the cable and they said that it works (if using progressive signal) so I guess that It should be a better choice. I will report about result (vga cable vs transcoder).

btw, you can use an EL4583 chip to get RGBHV (VGA) from the PS2's RGB with composite as sync output. Only $10 if you're up for the soldering. Same cabling and everything will work for PS3 as well.

The Wii is the only thing you might need this for. I don't know as much as I'd like about exactly how it's video works. How well does the VGA cable work?

Actually, come to think of it, I don't think all PS2 games output 480p (shouldn't matter RGB or component). Will your monitor accept 15kHz or do you need to be scaling?

A few games runs @480p on ps2, most are 480i. I'm just interested to play a few vs fighting such as Soul Calibur 2/3 and Guilty Gear X. For 480i games I will take the Extron solution (480i to pseudo 240p).

My cabinet is a New Net City (Tri sync) "scaling" is not needed :).

Doesn't help you with your Wii or your quest for a transcoder, but you know that you can use your Extron for 480p from a PS2 as well ?

If your PS2 is set to RGB, it will output RGsB (on the three R/G/B lines) to the Extron while in 480p mode. The Extron will convert the sync signal and output RGBHV or RGBs depending on the output you use or the dip switch settings (some Extrons have both signals active on different outputs, while others switch with their dip switches). This is clearly the best solution for 480p on a PS2. Much better and easier than using a transcoder, especially since the RGsB signal from a PS2 is cleaner (less noise) than a component signal.

Maybe just use it this way and get a "VGA cable" for the Wii. They're ok (with internal transcoder chips).

No, I didn't know :). I will try both solution, thanks.

The only difference (assuming quality is the same) is that Extron RGB add 1 frame of lag (doesnt matter much on this setup).

I still don't think that this can generally applied to all interfaces. Also it's the same as your 480i to 240p conversion and with a lag-free CRT I certainly wouldn't mind 1 frame.

I will verify this (unless it's already on your todo list for Leo Lag Tester ?). I agree, 1 frame is nothing.

On my TV set (Sony 52" LCD) I got 1ms less for "1080p via VGA > Extron 203xi > TV" compared to "1080p HDMI directly to the TV". Due to my cabling I couldn't compare it to a direct VGA connection yet.

Does the Wii VGA cable work with 480i and ~240p from virtual console, or just 480p?

About the Lenkeng LKV7600 converter, if I feed it with a 480p Y-Pb-Pr signal and I set it to output 480p VGA, does it make any scaling or does it simply transcode?

Also, I understand it accepts a 480i Y-Pb-Pr signal. Will it work with an input signal that changes between 480i Y-Pb-Pr and 480p Y-Pb-Pr?
