Converting TV signal from Amiga to HDMI?

[djos]

Agreed. I am curious as to what your SCART to HDMI converter looks like then. Perhaps you found a better one than mine.

Mine is identical to DanBeever's unit he posted pics of HERE.

4 pages of discussion when the solution was nicely summarised by paul1981 in post #5.  

The indivision not only provides the best quality output but also provides 1024x768 and 1920x1280 resolutions.

That's all well and good if you only have one Amiga and it's an a1200!

Personally i have 4 Amiga's and eventually managed to buy a Sony Trinitron Pro Video Monitor for every day use (scored it for $36 aud from a Uni Film & TV school) and I use the RGB-YUV converter with my TV's on the odd occasion I have time to use them.

[djos]

They make Indivisions for all models of Amiga.  I use them in my A500 and A2000 and would never go back, or consider any of these hacked up, "save a penny", jury-rigged solutions in these threads.  But, have fun with that!  

The Indy's are about $200 aud each (~ double the price of an a500), that's bloody expensive - if Jens had any sense he'd make an affordable external version ... I know I'd buy it

PS. my Sony PVM is not a "jury-rigged solution", it supports 15kHz RGBS natively ... it also supports Chroma/Luma and works great with my C64.

[djos]

It is spelled, "DanBeaver," as the last name is British, derived from "Beaverbrook."

Lol sorry, my bad.

[djos]

Last I checked this was an Amiga forum. And the subject of the thread was "Converting from Amiga".  Smart ass.

I'd be surprised if most of us didnt have more than just our Amiga's that needed 15kHz video support.

I have the A500+ using an Indi ECS, no issues. The picture is a lot sharper than when I had a SCART setup.

For quality from bad to worse SCART -> Svideo adapter from Amigamaniac -> Indi ECS. If I had to choose the cheapest and best option it was the Svideo adapter + Svideo to HDMI adapter.

Best solution not including price, Indi ECS.

Same situation for the A1200 which I can also use the Svideo adapter. Love the 1080p WB screen with the Indi Mkii.

As for other consoles, my DC has a VGA adapter box. The Master system has been modded with onboard component and other interesting mods etc etc....

I've got Kipper2k's S-Video/Composite adapter and the picture from that on my TV's is fantastic ... but then my Pioneer and Sony TV's do have very good video processing electronics in them. I would say that the PQ is only about 5-10% less than using my RGB-YUV converter.

The benchmark for me is my 800 line 14" Sony PVM-14M4A Professional CRT Broadcast monitor which natively supports the Amiga's RGBs signal ... the RGB-YUV converter produces a picture so close to this it's not funny, in-fact on my 50" Professional Pioneer plasma Monitor I'd say it's damn near perfect in every respect. My Plasma also supports the Amiga RGBs via it's VGA port so I can compare the 2 and despite being a PQ Nazi I have trouble telling the difference.

Btw, it's worth noting that the conversion from RGBs to YUV is a relatively simple mathematical conversion and doesnt require scaling or any other processing.

[djos]

I hate to throw fuel on the fire, but a thread on EAB. (http://eab.abime.net/showthread.php?t=76349) about the Framemeister (http://solarisjapan.com/products/xrgb-mini-framemeister-compact-up-scaler-unit) May do this.  Big Dogs with deep pockets ($300 USD) need only apply.

You can buy a DVDO Edge or VP30 for less than that.

[djos]

Those were not discussed in the thread.

You can read about almost every Video Processor ever made and it's retro performance here:

[djos]

I'm sorry but have you checked prices & availability (DVDO Edge is discontinued and only for sale on eBay beginning at $202 USD used or $500 new) and the DVDO VP30 is $2000 USD (or used on eBay for $185 X1 vs $230 USD).

I've seen them second hand on eBay for less then the $350 USD of the FM on a regular basis. Setting as they are a proper home theatre Video processor they are imo a much better value purchase.

[djos]

The seller agreed to send me another unit. It does seem unlikely that the converter box would fail though.

I am starting to question my RGB to SCART cable. Yes, it works fine with the SCART to HDMI box, but I am reading that not all RGB to SCART cables are the same. Perhaps this new box is a bit more sensitve.

@djos, did you say you got your cable at AmigaKit also?

Yep, both of my Amiga scart cables are from amigakit and both work fine with my RGB to YUV converter, however the converter only works with 2 of my 3 tv's. The tv which doesn't seem to like the sync or mode or something.

[djos]

Hmmm.....here is another possibility:

http://en.wikipedia.org/wiki/Component_video

Perhaps I am dealing with the difference between RGB and Luma Component. The Amiga RGB to SCART is sending out RGB and is presumably staying that way through the converter box, but my display devices are expecting Luma-based component.  Sigh. Since I will not be able to change the expectations of my display devices, this could go nowhere.

However, what if there are other versions of the SCART to Component converters? I don't think they distinguish between the two, however.

Correct, there are multiple RGB to YUV converters out there, I have 2 and only 1 of them works with Amiga Video due to the sync method used.

Here is the one I have that doesn't work, if you look at the board layout you can see that this one takes the sync from the composite signal of the scart connector.

So I wonder how I tell which one I need to get. Apparently, this one has trouble with the Amiga:

because that is the one I purchased.

That's the one I have too and it works perfectly on two of my three tv's.

[djos]

Ian Steadman's schematic has a 330 ohm resistor on the Csync with the RGB going straight thru

His latest version had 220uF caps on each of the RGB lines Iirc.

[djos]

Oh, you mean the schematic that says, "Provisional design for trial use only?"

yep.

[djos]

I love my new Framemeister!

And I love my Sony PVM14M4A Trinitron monitor.

[djos]

Good work, Im gonna buy one and try it on my TV that doesnt currently like converted Amiga-RGB to Component.

PS, I have their C64 video cables and they are great.
