Newbie RGB to NTSC question

kaeruthefrog · Mar 12, 2010

I've been wanting to get an MVS for a while but I've been putting it off because I'm not very clear on the best way to convert the video to TV. Googling I see information on the JROK and Neobitz. I also see scart converters and sync cleaners. So I ask:

What are different methods of converting RGB to an NTSC TV?
What are the pros and cons of specific products?
Where can I but this stuff?
Right now I'm only concerned about getting an MVS hooked up but will one solution work with other arcade boards or consoles?

Thanks a lot for any information that helps be get my head around this.

If you think even for a second that you'll eventually want to use this for something besides the MVS, you're best off getting a JROK encoder with a sync cleaner. The compatibility of the chip used on the Neobitz is not as good for other boards.

You can use the JROK contact page to get pricing and availability info.

In my opinion you would be much better off buying a SCART to Component converter. Much better quality video than NTSC, and you'll be able to use it for consoles, etc. as well.

What is a sync cleaner? How does it work with the JROK?

I was planning on component output anyway. What does a SCART converter do that the JROK won't?

A sync cleaner cleans up the composite sync signal on an RGB output. Some hardware will not have a stable picture (or sometimes even a rolling picture) without one if you are using a TV. The JROK boards are only $10 and are an essential item for using arcade boards on TV's.

A SCART to Component converter such as the Cypress CSY-2100 will give you a slightly better quality picture than either the JROK or Neobitz, and it will allow you to simply plug & play any SCART device into your TV.

To achieve this with the JROK, you would need to build a custom box and solder it up to a SCART socket, DC power socket, etc.

If you only plan to use Component then a Neobitz with a sync cleaner would be better than the JROK. The JROK component circuit is oversaturated on a bunch of arcade systems.

Is there one that works just as well with left and right audio output as well. I looked the CSY-2100 up and it looks like it is specifically for video.

So a SCART converter does the exact same thing the JROK and neobitz do but in a nicer package? Would I need a sync cleaner with one as well?

XX: I have heard the Neobitz has terrible compatibility with arcade boards other than MVS.

systmdfect: The lack of audio outputs is the only problem with it. I can't even begin to understand why they didnt include them.

Composite/S-video: JROK>Neobitz
Component: Neobitz>JROK

and you can buy a sync cleaner here:

/that's where I bought mine

I agree with this. I used the exact combination when I built my Supergun and haven't had any problems.
