    This is interesting: https://www.youtube.com/watch?v=lHKYvbVG5rI

    RetroTINK-2x. Composite, S-Video, Component to HDMI. Supports 240p/480i/288p/576i passthrough with 150 microseconds lag. Can be used with a HDMI to VGA converter to use it on the OSSC.

    Finally!
    Thanks for the heads up.

    This looks great, but, since it has line-doubling baked in, and it only has digital-out, what would be the point in using it with an OSSC? Wouldn’t it make more sense to use this instead of an OSSC for composite and S-Video devices?

    I’m also assuming there’s no chance (anytime soon, anyway) of a board like this that has analog in and analog out.

    Yea you could just connect the RetroTINK to the display but with the OSSC you are able to use lineX3/4/5, scanlines and mask features. Some monitors force everything to 16:9 so using lineX3 4:3 or lineX5 is also helpful for aspect ratio.

    Plus the OSSC has fully customizable timing parameters.
    The typical HDMI to VGA adapter use Lontium LT8511A which has quite good quality and is lag free.

    That looks like a super product, either standalone or as something to use with the OSSC. I’ll try to get in contact with him ASAP.

    That sounds like a good justification for adding an HDMI input to the OSSC.

    Looks like Mike Chi’s RetroTINK-2X uses a PIC controlled ADV7280 with ADV7513 HDMI transmitter.
    http://www.analog.com/media/en/technical-documentation/data-sheets/ADV7280.PDF

    The ADV7280 has a TON of options but Mikes PIC controlled design has only two buttons to disable “ANTIALIASING FILTERS” and switch (mux) inputs, all else at default.
    The chip itself can do Contrast, Brightness, Hue, Saturation, Test Patterns, C/Y Filtering, DNR, and a LOT more advanced parameters.
    The output is 8bit YCbCr 4:2:2 (ITU-R BT.656), but it’s well beyond good enough for Composite and S-Video.

    Hopefully his product will be reasonably priced (around 65$) like his other RetroTINK designs.

    Had a very productive conversation with Mike today on Skype and he’s willing to work with us towards bringing a batch of these to market. I’m now hoping to have a prototype of this device for testing soon so I’ll keep you all updated.

    Great to hear. Would save us europeans a lot of money if we can order it from the UK.

    Could you ask him about adding an adjustable Hue setting for NTSC sources? It would be nice to be able to tweak the NES colors like I can when I connect a NTSC NES through composite to my TV.

    Great news indeed!
    Man I really hope the price is right, considering it will be an “add-on” for people that already have the OSSC.

    What about this https://www.ebay.com/itm/Composite-RCA-S-Video-to-RGB-Component-Video-Converter/250431809472?hash=item3a4ee627c0:g:uAAAAMXQTT9RroAV
    ?

    I know it was reviewed here, but it was only tested with a PAL Commodore 64 (which people in the comments said isn’t the most compliant signal).

    Any further updates on the RetroTINK-2x

    I just solved this problem in my setup, with the DVDO VP30. NES and 3DO are the last consoles I haven’t converted to RGB output and probably won’t, although I did do the 240p mode on the 3DO.

    DVDO VP30 YPbPr out -> OSSC AV2 in

    Routing audio was a little tricky due to the VP30 not having a analog audio output. Digital audio is only active in conjuction with digital inputs, while analog audio input gets injected into the digital video output…but again, no available analog audio output. Just be forewarned, if pursuing this as a solution, you will have to solve for routing audio into the OSSC.

    Anyway, below are some screen grabs from both consoles. It’s not jaw-dropping like RGB directly into the OSSC, but it looks pretty good for what it is, and in the case of the 3DO, because it is progressive, it has very little lag. And you also get the benefit of being able to enable scanlines. In both cases, the DVDO VP30 is outputting 720x480p.

    This obviously doesn’t solve for RF, but maybe helps get a little closer to a solution.

    We’re expecting a prototype RetroTINK-2x in the post really soon.
