So, I was thinking about building a setup for both original Xbox and Wii. These two consoles have a quirk: they only allow 480p signal if plugged via component cable.
The problem is that I have a huge SCART switch but I haven’t a YPbPr one (I would not like to buy one either for just two consoles). So I was thinking about buying two of these:
Since SCART can handle YPbPr signal, I was wondering if it could be used in an OSSC setup.
That would save me a LOT of money…April 4, 2017 at 9:11 AM #12195
Yes, I believe so. As long as the wiring is standardized, which I can’t confirm cos I never used one.April 4, 2017 at 11:00 AM #12200
So there should not be any problem at all if I use a Wii with YPbPr out, connect it to a passive YPbPr-to-SCART converter, then to my SCART switch and finally to the OSSC. Am I right? Can anyone confirm this?
Thank you!April 4, 2017 at 7:32 PM #12207
It should be fine if your scart switch is ‘dumb’, i.e. does not need status voltage or dedicated sync line to switch on target input.April 4, 2017 at 11:32 PM #12219
So, things like Gscartsw or W-Hydra (×16 SCART ports) should work fine with this, shouldn’t they?April 6, 2017 at 3:51 PM #12253
GScart won’t work as it uses the composite video/composite sync line to detect inputs. I’m not sure what Hydra uses (waiting for Lotharek to get back to me).
I feed in component video to mine using an Extron Crosspoint, works great. I don’t use the component video inputs at all.April 6, 2017 at 4:03 PM #12254
The GSCARTSW will default to port 8 if it can’t detect sync… So you “could” have one of those plugged into the GSCARTSW and it’d work fine (it’s what I do for the PS2’s RGsB/sync on green).
The Hydra has the benefit of a manual switch.
Just wondering though, where did you find the SCART adaptor with the R/L audio channels? eBay/Amazon (UK) aren’t throwing up anything for me.April 9, 2017 at 6:57 PM #12306
@buckoa51: Hm, I’ve talked to Superg, the creator of Gscartsw, but maybe I should contact him again on that topic.
Component cable is a must for both Wii and Xbox, I am afraid. Other cables would output 480i only, while YPbPr cables output 480p (and 720p in some Xbox games). That’s why I want it to run through a SCART cable and be compatible with Gscartsw (or other devices).
@vmagix: I would love to know if there is another workaround with this option.
There is not a YPbPr + Stereo audio to SCART adaptor. It doesn’t exist. Why not? Don’t know, but it’s true. However, Europe has millions of composite+audio to SCART adaptors. So what I want to do is some sort of custom adaptor. A custom PCB with a custom 3D printed case would be the thing. If you are interested, please ask (or suggest, as I’m confused about the use of it along with Gscartsw).April 9, 2017 at 9:30 PM #12308April 9, 2017 at 11:32 PM #12311
Oh, thanks a lot, @marqs!
Now you mention, some people at Shmups are saying that the proper way in order to make this work is:
Y — Pins 17 and 20 (those used for composite video)
Pb — Pins 5 and 7 (those used for blue in a RGB signal)
Pr — Pins 13 and 15 (those used for red in a RGB signal)
Audio — Pins 2 (R), 6 (L) and 4 (ground)
Y is being routed to composite video pins instead of green ones because of Gscartsw. It detects the source at pin 20, so if there’s nothing there, it won’t detect it as a valid source and will ignore it (unless it’s in port 8).
The thing is, would the OSSC be able to handle a YPbPr signal using that setup? In other words, Y signal through pin 20 would be accepted by OSSC?April 9, 2017 at 11:54 PM #12313
No, only sync is processed from pin 20, not luma.April 10, 2017 at 12:01 AM #12314
Hm, so the only way would be finding a SCART switch that allows manual selection, am I right?
