Bumped:)

Got pics of the component vid from the geni?

[turbokon]

Just installed it on my geni today

[xcrement5x]

So, is is possible to run it on a Genny using the output from the rear AV connector? 

Basically, this is what I was thinking:
Tap the pinout, add the 1k resistors after that(are they on the RGB lines or the sync, or both?), then wire them to the board.  Finally tap the board out for the component and run to your TV.

Does that sounds like it would work or is it madness?

[turbokon]

Yep, you can do that. Thesteve just tapped it from the back connector of the genni. You only need to add the 1kohm res to the RGB signals only, no need to add to the sync. You can get +5v and ground from the connector pinout also.

[BlueBMW]

So like an external component encoder that isnt rediculously expensive?

[thesteve]

yep

[xcrement5x]

So like an external component encoder that isnt rediculously expensive?

Exactly what I was thinking

I was thinking it would be cool to make more of a black box type thing that I could plug input from off a console, then it does the component conversion.  If I could find a Nintendo AV plug with the correct pinouts then maybe people could finally get GameCube component cables that don't cost a bajillion dollars too.

[turbokon]

Maybe that's something Shapeways can make with 3D printing. Someone else will have to take this on and work with Shapeways.

[darkgunsou86]

can someone try it on Nintendo 64? SNES too if possible. these consoles have nice games that I want to play using component output.

[BlueBMW]

I'm sure it would work on the N64 and SNES, we just need to figure out the right way to modify their RGB signals.

[turbokon]

I'll try it on a SNES this weekend.

[turbokon]

Thesteve and I confirmed it works with the Snes:) More systems testing to come.

So overall what is the end result of this component mod/board vs RGB?

I'm going to test my Bravia for 240P happiness. I don't think that my Denon receiver will pass the signal properly, so may have to send video to the TV directly and sound to the receiver. Only downside is more remotes/button presses to deal with I suppose.

[sirhcman]

man I wish one of my tvs accepted a 240p signal the quality looks amazing!

edit: time to go dust off the old lcd down stairs to see if it accepts the signal.. dammit only 480i and 480p

I never done a rgb mod before so I can't tell you how they compare with the component video mod. From what I've read, raw rgb is almost unusable without some sort of amplification circuit.

Did you try pluging the composite RCA to the "Y" of the component input? If it support 240p, you should see black & white pictures.

no, just checked the specs online for all my televisions. will try it on a couple tho to see what happens

Yeah I like the board you've created and it seems easy enough for me to tap the expansion port (I'd put this in my CD Dock). I'm just wondering if RGB is significantly better picture wise than component. Like if composite is worst, then Svideo, then Component and then RGB. Unfortunately pictures on the internet usually don't do what everyone is seeing on screen in person justice.

I know that you can't answer the question personally not having done an RGB mod, but would be interesting to get someone's take that have seen both.

[thesteve]

i have done both
in my case my plasma misidentifies the component as 480I (which works)
but it properly id's RGB as 240P making it look better
component has the same colorspace as composite, whereas RGB is full spectrum color

[turbokon]

I read some where that component signals are less susceptible to colour errors (instability and phase) than the RGB.

[Marll]

So for component are you getting the same colors as composite, just clearer, which RGB provides more color and clarity?

[stockspyder]

I know it's a dumb question, but I didn't see it on the PDF. I've never done a component mod before or wired component before, but looking at the pics it's difficult to tell. Are you just wiring each color to each component output, or are they all attached to the ground wire as well?

Thanks for your help

[turbokon]

The outputs will need to be grounded as well.

[xcrement5x]

Just bought one of these chips and can't wait for it to get here to try making a Genesis component cable.  I'll need 3, 1k resistors right, is is possible to give you a bit of extra cash to get them shipped with the board?

[turbokon]

Oh man, I just shipped out the boards to you. I still need my web guy to add a drop down option for the genni & SNES.

[xcrement5x]

Lol, no problem.  You're just too customer oriented and ship stuff out fast! 

I'm sure I can get them elsewhere, I meant to ask sooner but got sidetracked. 

[turbokon]

My web guy have added a drop down selection for the different systems this board currently works with. More systems to be tested and added later.

[cloudd]

I was trying to purchase one of these Component boards from your website but there is no option to ship to Canada. Do you ship to Canada?

[turbokon]

Sure, shipping to Canada shouldn't be that much more.

As far as I can tell, this (like many questions) is a very subjective answer.  However, the most common answer I've seen is "YPbPr and RGB are basically interchangeable for most people's perceptions", meaning that while RGB may in theory be a touch better, the average human eye won't be able to tell the difference.  I know I can't tell a difference with any pictures I've seen (which you seem to intimate is the same with you -- I also don't have any RGB or scart connections to test), and I know I CAN tell a difference going from S-Video to Component on my various systems (some more so than others depending on how good the S-Video was).

Take that for what you will, but I for one am happy getting things into YPbPr rather than monkeying with converters that are bound to add lag in an effort to turn RGB into HDMI (since there's no real other way to use pure RGB without finding a PVM or something).

That reminds me, I really need to send turbokon my Jaguar so he can test that one out

well put
any TV using HDMI is using component encoded video anyway
if the tv supports tint/hue/brightness/contrast adjustments its transcoding to component anyway
so rarely except on PVM's do you ever get pure RGB video paths anyway

[turbokon]

I had to add a disclaimer to the front of this thread.

[turbokon]

Bump:)

[c0ldb33r]

I wanted to give some feedback in this thread. I had turbokon do some work to my PCE Duo.

In particular he did the following:

• Install component video output - using built-in component jacks
• Install region mod with rocker switch
• Install power LED
• Do complete cap replacement

The work turned out wonderfully. My duo had terrible audio issues, and had to warm up before I would get any CD audio. Now it works 100%. The region mod works perfectly too.

The video output is amazing. It simply can't compare to stock composite. The video is just as clear as using an emulator!

The picture quality below isn't perfect since I took the pictures with my phone. The third picture (NEC/Hudson) really shows how incredibly clear the picture quality is. The middle photo shows the component jacks (in the back) and the power LED.

[turbokon]

Is there anyone out there who would like to create an install guide for the Genesis & SNES for me in exchange for free component video boards?

I'm working on building a cable with mine off the AV port in the back so that I don't actually have to drill holes in my Genesis, not sure if that qualifies but I'll try and snap pictures as I go through it all.

[turbokon]

Yeah, that could be an option for peeps who don't want to drill into their systems.

Just wanted to chime in about this.  Component Video (YPbPr) and RGB are both lossless formats.  They're exactly the same quality. 

The difference between the two is that YPbPr uses algebra to calculate the color signal to save on bandwidth, while RGB just carries the signal in 3 channels.  Component video takes luma for black and white, and takes Red - Luma and Blue - Luma to calculate the green. 

So there's no difference in quality.  There may be slight color differentiation going on however, this is due to the mixing when converting RGB -> Component, but the video quality and clarity are exactly the same.

[turbokon]

Thank you for chiming in Conhuevos

[Platinumfungi]

Just wanted to say awesome work  I haven't been here on the forum in ages, so it's great to see everyone is still rocking the scene and developing newer and better gear.

Keep it up!

[turbokon]

Thanks Red. The result was a collaboration between several of us. Wouldn't have been possible without all the valuable resources we have here. Btw, welcome back

[technozombie]

I wouldn't mind doing this but I would need a guide to show me how to do it so I could make a guide...........

[turbokon]

You can tap RGB, sync and 5V directly from the genesis and SNES a/v port.

Genesis:


SNES:


Or you can tap from the encoder chip, don't know the part number for them at the moment.

[technozombie]

I'm going to order one of these from you on Friday,I've already spent my mad money for this pay period lol.

[technozombie]

Ok order placed, I'm a newb at this but I'm going to try to make a guide. I choose the Snes/Gen option, does that mean it will come with the 1k resistors?

[turbokon]

Yep, it does. It will soldered onto the board for you. I will send you two so that you can do it for the genesis and SNES. Do you need parts? Like wires, RCA jacks?

[technozombie]

I don't have any wires, I was going to try to scavenge some or hit up radio shack. I placed an order last night on digikey for some RCA jacks and some oscillators to over clock the genesis later


Wow, thanks for sending 2, I hope the guide turns out well I'm going to try to take a ton of pictures and make my wife help me.

[turbokon]

Techno, the boards went out to you yesterday.
