    Not much to report on the OSSC Pro front right now, Markus is still hard at work on the firmware. Right now the device does basic line multiplication as well as adaptive line multiplication, which should make it compatible with almost all displays.

    One cool feature that was planned for the OSSC but never made it was downscaling. On OSSC Pro, you will be able to convert 480p to 240p. I tested this feature today with an original Xbox running at 480p and posted some results on my Flickr. If you have an old CRT in your gaming setup, prepare to breathe new life into it by playing all your favorite retro style indie and 2D titles on it again in glorious 240p πŸ™‚

    Is this a typo?

    No, that’s exactly what I’ve done here.

    I assume that it will support 480p to 480i and 240p, and 480i to 240p? I can think of a few use cases for all of those:

    – 480p to 480i: Connecting a PC to a BVM/PVM/CRT TV
    – 480p to 240p: PC/console/Pi/etc. retro games to 240p
    – 480i to 240p: 240p-as-480i games like the wiiware stuff where the games render at 240p but output 480i

    1) Unlikely in release firmware, but should be possible Markus just confirmed this over on Shmups.
    2) Confirmed above πŸ™‚
    3) Yes, confirmed!

    Since it’s going to be a proper scaler, as opposed to a simpler line multiplier (like the regular OSSC), it should be capable of both. My understanding is that it’s intended to have deinterlacing that will be game-focused (as opposed to most deinterlacing solutions, which are intended for video and film).

    Good deinterlacing isn’t trivial, the device will be capable of fantastic deinterlacing but what it will have when it is launched I don’t know.

    Exciting stuff, OSSC Pro is going to be the master of all trades!
    Can’t wait to get mine. πŸ™‚
