As some of you may know, the original xbox is really lacking in video output modes for the modern era. It is only capable of analog video out, and doesn't even support VGA through that.
Early versions of the xbox use a CX25871 as the video encoder, which can take a variety of digital inputs and in turn outputs analog video.

My suspicion is that the xbox uses the highest quality of these potential inputs, RGB24. If that turns out to be the case, I should be able to use the Texas Instruments TFP410 to turn these signals into DVI

End goal is to have a board with a BOM of under $20 that I can then install in my absurd stack of xboxen.
The catch: This is my first circuit design project and my first PCB design project, so I'm starting out way over my head. Wish me luck, I guess.
