Best cheap scaler for 240p?

[rendermatt]

Is there any s-video to vga converter that doesn't try to deinterlace 240p? One that doesn't try to combine frames and have that ghosting effect. And reasonably priced so 60$/40£ or less. Thanks a lot

[fagin]

For £40 I think you may struggle to find a linedoubler that recognises 240p correctly via s-vhs!

Keep a look on eBay.... every now and then you will see Cinemateq Picture Optimizers for sale. These will do exactly what you need and also have the added benefit of Video, RGB SCART, component along with S-VHS input.

I picked up two of these last year I think for around £60-£70 each.

[rendermatt]

Thanks a lot fagin! I'm surprised it has all those inputs. Seems like the ideal machine for me. This will output 480p for use of a SLG? And do you set the resolution, or is it always double the original?

[fagin]

It depends which CPO you get.... Not all of them work directly with the SLG. The sync polarity needs changing.

Just bought a Picture Optimizer for $65! http://www.ebay.com/itm/Cinemateq-Pictu ... 5ae4762935

The T-SLG has a sync polarity switch and I'm thinking should work with either polarity, see post 485

I'll post results here

please do ! And nice find on the Cinemateq - they are so rare in the USA. I wonder how it got into the States in the first place

I really hope you have a remote control with that CPO. There is no mention of it in the advert and the unit is TOTALLY useless without it.

[rendermatt]

Thanks fudoh

I hope so!! Maybe a universal remote would work with it

[fagin]

Have you asked the seller?

Nope... the remote is unique to the CPO.

Fingers crossed for you.

[rendermatt]

Yeah they just responded, no remote

Found out that the POP and POPII both use the RC-5 0x15 IR remote protocol and the SAME codes for all functions.

POP codes http://www.cinemateq.de/uploads/43.pdf
POPII codes (p.52 of pdf) http://www.cinemateq.de/uploads/245.pdf

So its likely the PO may use those too. Or did you mean that a POPI or POPII remote will not work a PO? Emailed cinemateq, if I can't get a remote through them I'll have to try these codes..my friend did an IR remote project like this once so I don't think its too hard. I've gotten myself in a mess here but thats all part of the fun right?

[Fudoh]

I'm pretty sure that all Cinemateqs use the same IR commands. If you can't find a cheap one, just have somebody with a Cinemateq processor (e.g. Fagin ) get a $10 programmable remote, learn the codes from the original one and have it shipped over. Definitely the cheapest way.

[fagin]

That's shit news.

The remote will work with all PO & POP's as far as I know. I have the CPO and the CPOPII. They both use the same remote.

I did see a remote on eBay some time back..... it was going for more than a complete unit. lol

Good luck and let us know how you get on.

[rendermatt]

Thanks for the help. So if you have the PO turned on, unplug it, and plug it back in, it will be turned off?

Cinemateq offered the remote for 87£ total, going to look into other options first haha

Would the one rendermatt linked work with the SLG3000? It outputs RGB HV / RGBS / RGsB / YUV, so even if it doesn't work directly I could use the GBS-8220 to transform the signal without quality loss, right?

No it will not work with the SLG3000 without a polarity invertor.

The CPO will do a much better job of linedoubling the image than a GBS-8220 will.

[blizzz]

I meant putting the RGBHV output of the CPO into the GBS-8220. As it's 480p in and 480p out it shouldn't do anything to the quality. Or would it be better to buy/build a polarity inverter (no idea how much they cost).
Or would it be best to buy a different linedoubler? I'm looking for a Vigatec FX2 or CPO Plus II, but those are harder to find.

Pass-thru is not to be trusted and I would be amazed if the quality of not effected. Since it's pass-thru you may even find the polarity going out will be the same as the input.

It's very easy to build a circuit (although I did struggle, but found out why that's OK for use with the CPO) or you can buy something like a Extron RGB Interface, as these will allow you to alter polarity by the flick of a dip switch. The Extron RGB Interfaces can be found for as little as £25 off eBay.

[fagin]

CPOPII has the inbuilt facility to invert the polarity.

[blizzz]

Thanks for your help. I'll see what I can find on eBay.

[rendermatt]

What about the TSLG http://shoryuken.com/forum/index.php?th ... st-6435115

[fagin]

Personally I don't think it's a solution to the scanlines..... it has no variable density, which I feel is very important.

It appears to resolve the polarity issue though.

[rendermatt]

Oh, you know it has a wide scanlines mode and a "RGB shield" (his way of adjusting brightness and color of scanlines) right?

http://godlikecontrols.com/images/shield.jpg

Not sure if his latest version will come with one, if it doesn't I'd just wire potentiometers to the jumpers next to the female VGA port. But of course thats not a solution if someone wants variable density out of the box

Would an Extron Professional RGB 202xi (Manual) do the job?
From what I get you can only force the sync with an internal jumper to -/-, but that seems to be what the SLG3000 needs. Just want an informed confirmation

[rendermatt]

Anyone use Cinemateqs in countries with 60hz AC power? It says 12v AC 50hz, but I'm wondering if it will accept 12v AC 60hz.

[Fudoh]

The PSU outputs DC, not AC, right ? There is no frequency in the DC output, just in the AC input, so don't worry.

[rendermatt]

Didn't come with a PSU, the device says "12 V AC 50hz" but in the POPII manual there is a picture of a PSU that outputs DC. Wtf Germany?
