yes, for 15khz RGBs you use the white sync input on the right of the component inputs and for 31khz RGBHV you use the black sync inputs on the left of the component inputs.by this do you mean they connect to a different input on the Edge?
DVDO EDGE - How it performs
Re: DVDO EDGE - How it performs
Re: DVDO EDGE - How it performs
Right I understand you now. Just to be doubly sure the Edge wasn't using the composite sync from the Amiga I disconnected the RGBC connector, 100% definitely works using the CD32's RGBHV 15khz signal and picture is definitely sharper. Shame about the tiny bit of wobble though. I really think this warrants further investigation, I'll get some pictures posted too when I have more time (have to get this darned ebook project finished).

Re: DVDO EDGE - How it performs
You're right!
There is a marked improvement between RGBs and RGBHV.
The EDGE recognises HV sync through the Sync Strike, but strangely enough you get no picture with the HSYNC switch activated on the Sync Strike. The HV sync recognition is with the CSYNC switch on the Sync Strike.
I have tried this with a PS2 480i and 240p video.

Re: DVDO EDGE - How it performs
I assume RGBs has the same quality as a component connection, while H/V sync gives a slight improvement over both ?
Re: DVDO EDGE - How it performs
I have never fed the EDGE with a true sync signal and I wonder if this is what makes the difference... between normally sending it a composite video for sync.
Nice find mate!

Re: DVDO EDGE - How it performs
Any instability/wobble on the picture when you used the sync strike with the Edge?
Really this difference should not be happening, this suggests to me that there is some additional processing being done to the 240p/480i signal when fed in through RGBC that's artificially softening the picture? Could this be fixed in a firmware update perhaps?

Re: DVDO EDGE - How it performs
Just a quick note, I fed a PAL60 240p signal from the Amiga CD32 through to the DVDO Edge and got "Unsupported Signal" with RGBHV, but worked as normal with RGBC and of course perfectly fine going Amiga->XRGB3->DVDO Edge......weird huh? Switching back to interlace everything worked again of course.

Re: DVDO EDGE - How it performs
Yes... massive amount on 480i (unusable in reality), but only very very slightly (hardly noticeable) under 240p from the PS2.BuckoA51 wrote:Any instability/wobble on the picture when you used the sync strike with the Edge?
Re: DVDO EDGE - How it performs
Ah right I see, strangely on the Amiga CD32 I get no sync wobble at all with interlace picture via RGBHV. Seems like we're certainly in undocumented territory with this. Considering the limitations we've both found it's interesting but not really practical in most instances. Now if we could just convince DVDO to make the RGBC look like the RGBHV picture does, at least when game mode is on.

Re: DVDO EDGE - How it performs
The plot thickens....
Just tried my Syncblaster cable:
480i unstable sync
240p 100% stable sync
EDGE see's the SYNC as RGB-CSYNC (as expected with the Syncblaster). Sync Strike shows as HV sync.
Picture quality is the same with both sync devices..... i.e. improved over RGBs input.

Re: DVDO EDGE - How it performs
Not sure I follow... The Syncblaster outputs RGBHV doesn't it? Are you saying you put your Syncblaster into the RGBHV inputs in the edge and fed them an RGBC signal and it worked?

Re: DVDO EDGE - How it performs
And the next test.....
PS2 --> Sync Strike --> EDGE (HVSYNC) --> HDFURY3 --> SLG3000 --> DELL 1080p
240p game
Image is far superior to that of the RGBs input (back to back). I would go as far to say that with scanlines, there is virtually (minute amount of ringing) no difference between this and the XRGB-2+! It's pretty astonishing the difference between RGBs and RGBHV quality, even with the SLG3000 in toe.
The image is sharper, less bleed and the colours are more vivid.
Weird!
Certainly the way to connect for 240p video at least, when using the EDGE.

Re: DVDO EDGE - How it performs
I was never sure whether the Syncblaster output HV sync.... this test would certainly suggest it doesn't as the EDGE showed the input as C-SYNC.BuckoA51 wrote:Not sure I follow...

I fed the SCART RGB to the Syncblaster. Syncblaster to DSUB15 to phono breakout. Breakout to RGBHV input on EDGE. It would only register the HSYNC phono input on EDGE. VSYNC phono made no difference whether connected or not.
Re: DVDO EDGE - How it performs
I see, so just by using one of the two black sync connectors instead of the white sync connector (that is designed for composite sync) the picture improved dramatically? fascinating! This surely means that the Edge can potentially work very nicely with 240p material just ABT/DVDO screwed up the firmware somewhere along the lines.
Any chance you could try something like this?
Sega Genesis/Super Famicom/Other NTSC console->Sync Strike->Edge (RGBHV)->Display
Just want to know if that works, since my CD32 sadly gave "unsupported signal" when I fed a 240p/60hz signal into RGBHV (yet 288p/50hz worked fine, very odd I know).

Re: DVDO EDGE - How it performs
JAP SNES
Sync Strike gives unsupported signal (whether CSYNC or HSYNC on sync strike or H/V Sync combination on EDGE connection).
Syncblaster gives picture with just the HSYNC input connected on EDGE. Registered as RGB C-SYNC. Connect both phono sync's and you get no picture.
Again picture is improved over RGBs input on EDGE.

Re: DVDO EDGE - How it performs
So the Edge accepts 15khz 60hz RGBC via its RGBHV inputs but not 15khz 60hz RGBHV...Talk about weird. I might have to write to whoever owns ABT about this, they would probably just ignore me though

Re: DVDO EDGE - How it performs
Hi just wondering if on my dvdo duo (the edges big brother with cms) would I use the vga input? The duo only has a vga input for rgbhv not rca inputs for the rgbhv like the edge.
Re: DVDO EDGE - How it performs
For 15khz you mean? You'd have to try it with something like the Syncblaster/Sync Strike, though Fudoh said he tested this and it did not work.

Re: DVDO EDGE - How it performs
I have tested the vga input with 15khz on my duo from a arcadevga pc card and it did show a pic. However I had a scrolling line from top to bottom repeating over and over. I did have both the h and v connected through on the vga maybe I will build a new cable without the v connected. I tested this a while ago. Also the duo can only accept a maximum of svga. I tried 1080i in form my sat receiver but the pic was way soft and squigly lines in some places. Not always just sometimes.
Re: DVDO EDGE - How it performs
Comparison shot time, sorry I only have a digicam to point at the screen, I'd much rather do this with a capture card but, even taking into account the fact I didn't get the framing the same each shot you can see a difference, first off, here's the Amiga going into the Edge via a SCART cable, playing a 288p game:-
Hmm, it's ok I guess, the Edge seems to smooth everything, maybe that's ok for video but not so much for graphics. Now, here's the Edge again but with the input fed in via RGBHV, still 15khz, nothing else in the chain except my Extron (which isn't really doing anything)
Ringing still quite pronounced but image much sharper! If only all 240p material was handled like this the Edge would be much better. Now for reference here's with the XRGB3 in the chain, so we are going CD32 15khz RGBC->XRGB3->EDGE->Display
Still the nicest picture and of course scanlines can be added, but the difference between 2 and 3 is not as big as 1 and 3. Bigger versions of these pics are on my flickr for reference (http://www.flickr.com/photos/32165624@N04/).

Re: DVDO EDGE - How it performs
If I get time later I will do a similar comparison on the PS2 with screen captures. EDGE RGBs vs RGBHV, vs XRGB-2+, vs scanlines on all options. Should be interesting.
Re: DVDO EDGE - How it performs
I wonder if transcoding PS2 component to VGA is worthwhile considering the results we have seen here? I wonder if any transcoders can actually support transcoding 240p or 480i component to 15khz VGA?

Re: DVDO EDGE - How it performs
Thanks for the screenshots so far ! I actually think shot 1 and 2 are pretty similar, just with different EE/DE offsets. Have you tried to mimic the 2nd result by adjusting those (only works with disabled gamemode) ?
I don't see the point. Do you expect a plus over going 15khz RGBs to 15khz RGBHV ?I wonder if transcoding PS2 component to VGA is worthwhile considering the results we have seen here?
the XSelect does so, most other transcoders probably as well even if it's not officially supported.I wonder if any transcoders can actually support transcoding 240p or 480i component to 15khz VGA?

Re: DVDO EDGE - How it performs
sorry, you misunderstood maybe. I probably wasn't clear after all.As you can see above (all shots in gamer mode) there is a big difference in quality.
What I don't understand is why you want to go from 480i COMPONENT to 15khz RGBHV (which requires a transcoder) when you can go from 480i RGBs to 15khz RGBHV by just using a sync splitter ?
Talking about source signals, the 15khz RGBs signal from the PS2 is *slightly* superior to the 15khz component signal, so that's another reason for not using a transcoder. You can even use 31khz VGA from the PS2 by using an extron interface which transform the sync on green 31khz signal to RGBHV.
Re: DVDO EDGE - How it performs
Well, it was just a thought, remember I have PS2/Wii/Xbox1 and Gamecube all hooked up via component. I don't see how I can easily go from Component (including 240p/480i/480p) to RGBHV on those systems without transcoding.
Maybe, but the RGBs signal won't output progressive scan for those games that support it, and I can't be bothered to cable swap.Talking about source signals, the 15khz RGBs signal from the PS2 is *slightly* superior to the 15khz component signal
