    Default Dc Component mod

    Since my Dreamcast's S-video cable is knackered and my tv doesn't have hdmi, vga or rgb ports I'm thinking I need a component mod. Is rgb the same as component? They look the same. My DVD player has a cable with red, blue and green ports like composite. Is that rgb or component?
    And, does anyone have a guide for a Dreamcast component mod that is relatively easy to do and inexpensive?

    Got an idea! What would happen if I cut my composite cable, stripped the ends so I had the 3 cables, one for each plug, them did the same with the component leads and soldered the composite plug to the component leads? I would have to ground pin 6 or 7 and then I think it would work...?
    Also, does component/rgb output audio or foes it need a seperate jack? More feedback would be nice thx.

    RGB is not the same as the component plugs going into your TV.

    In your TV you have what's called YUV, which is Luma, Blue-Luma and Red-Luma whereas RGB is 3 pure signals of Red, Green and Blue. While the Dreamcast does output Luma (Y), it does not output U and V. You can plug Luma into the Green plug of your TV and play in black and white if you wish.

    Your idea of plugging composite to component won't work, they are different signals.

    Only way to use component with the Dreamcast is to get a transcoder/upscaler that takes VGA and turns it into YUV. You'd need a vga cable and a transcoder. In your situation, Id just buy a new sVideo cable. Or maybe a VGA cable and plug it into an old PC monitor.

    EDIT: YUV, RGB and VGA don't carry audio. You need a different plug.

    Pretty sure you will need to encode the RGB to component with some sort of video encoder IC and audio is separate. The is a thread about doing just this on this sub-forum:

    Ok, well it sounds like its easier to just get a new s-video cable. I guess I'll do just that.
