Title: The Ultimate solution for those that have TV with component
Post by: tisurame on August 25, 2004, 05:40:55 pm
TC2000 is the only transcoder in the market that only do the colour conversion between VGA (RGB) to VGA YPrPb (Component), with no additional conversions or process involved.

This means that programs like AdvanceMame will have total liberty to handle the video signal, with no interference, just like if you are using a arcade monitor.

I bought it and works great. No doubt this is a much better option than a arcade monitor.

Looks like the TCP2200 would be the better way to go to me.  Why did you purchase the external version over the internal one?

At $139, I'd rather take an old 25" TV tube and a $99 new  Arcade monitor chassis and build a 100% RGB compatable monitor and not futz with signal conversion and the signal loss that occurs.

But definitely acceptable if you don't wnat to futz with building a monitor and dont mind spending $139+cost of TV with component.

Thus why all of us aren't named, "MonitorGuru."   :D

I was given an older 27" zenith television that has a good tube but a flaky tuner.

Are you saying that it's possible to make a 27" arcade monitor out of it?

Any tips or resources on how to attempt this?

Yes tons of them. Search for "8liners" in this (Monitor) forum.   Enjoy!

It's certainly not the only one that can transcode RGB to YPrPb. Also, the Crescendo TC2000 has a flaw: it outputs 480p meaning it cannot transcode 15kHz RGB to 480i. You need 480i to get a true arcade resolution display. For the money it's overpriced as you can get a similar product (http://www.lik-sang.com/info.php?category=219&products_id=4233) for $60.

I would recommend getting the Micomsoft XSelect D4 (http://www.micomsoft.co.jp/xselect-d4.htm). It's only slighty more expensive, has many more inputs and comes with a remote control. And more importantly it can also transcode 15kHz RGB to component for authentic arcade displays.

b3eatmania, looks like you're missing the point: the original poster just wants to convert VGA device -> Component display, i.e. a PC displaying on a TV. The purpose is to go one step in quality above S-Video, and still below RGB monitor costs.

On the other hand, the device you recommend is for Component device ->VGA/RGB display, i.e. a DVD displaying on a VGA monitor or RGB arcade mon. I see the value on this, but it is totally different than the application described above.

Finally the only situation I can thing of where you want to transcode 15khz -> Component is in a supergun type of application. Not what the original poster wants to do: he wants to connect a PC, not a gameboard to the component TV.

Is that $139 converter really required to go from a VGA PC output into an HDTV with Component Input? Obviously, I'm not a monitor expert, so I appreciate any thoughts (in layman's terms).

But, I thought that an HDTV basically had similar resolution to what a PC monitor puts out. It seems like there should be a less expensive method of getting the PC output onto the HDTV; but maybe not.

Here's another way to sort-of ask the same question. What do you get if you take an RGB-to-Component cable and plug this into your PC monitor output and HDTV component inputs? I.e. what kind of picture do you get on your TV? What's the resolution? How does it compare to S-video?

Cheers.

Actually, from one of the linked reviews and the PDF manual on their site, it can just pass the timing through; it will display 480i. The silliness with 480p on the site is it does specific color conversions for 480p and a few other resolutions.

Nope, the XSelect D4 can transcode component to RGB, but also RGB to component.

Even with a PC you want to output 15kHz (480i) for authentic arcade emulation. If you output VGA (480p) you are viewing the game in a way totally different from the original arcade game. It's simply not authentic. For the same reason, true fans buy an ArcadeVGA (or use AdvanceMAME) to get their games running in their authentic resolutions and refresh rates.

b3eatmania, but what is your guarantee that this device will convert RGB to component without, absolutely, no additional conversion, additional conversions that all others transcoders do.

I'm almost sure that this device only works with fixed resolutions and frequency only, there is no reason for the contrary, since it would not work for the general target customer.

So, it's no usefull.

This will not work.

Hi,

I know I am royally late in replying to this thread, but I just found it doing a Google search. I am the manufacturer of the TC2000 and TCP2200 transcoders and I thought it would be best to clarify a few things.

1) The Crescendo transcoders only change the color space of the signal and do no further processing whatsoever.

2) The transcoders are fully transparent with respect to timing and can handle any timing, interlaced or non-interlaced, that the user can throw at it. The largest roadblock in using weird timings is the ability of a TV to display it. With regard to the transcoder "Timing in = Timing out".

3) According to the appropriate standards, the color space in converting RGB to component for a 480i signal is the same as for a 480p signal, only going to higher resolutions like 720p and 1080i makes the color space change. The difference is not that great and I wonder how close the TV manufacturers adhere to the standard. Considering the scorch mode that most TV's come in probably not that well.

I hope that this has clarified a few issues, even if it is a bit late.
