So I've been OCDing over this for the past month. So RGB to NTSC has good options still for a diy. What abut YPbPr (Component)? I've found a few circuits, one using a discontinued chip (The ROHM one). A circuit using two amps, but require -3.3v. Or using a bunch of transistors. Is there any good replacement for that rohm chip or an equivalent amp that just uses a standard 5v or 3.3v? I can probably find the ROHM encoder on ebay (I can), but would it be legit? Are there any ICs that do composite, svideo, and component? I've been wanting to mess around and make a DIY of that very spiffy JROK encoder, but I haven't figured out how he gets component.
