What are the waveforms supposed to look like for YPbPr? I can find heaps of information on google about composite video, VGA, and some about the Y component and understand what those waveforms are supposed to look like on-the-wire in an actual application, but PbPr information seems scarce as far as actual oscilloscope style displays go, even though I know Pb is 0.565(B-Y) and Pr is 0.713(R-Y). The top part (RGB->YPbPr) is pretty much verbatim from the application note, the only thing I have added was the bottom part for adding the sync information to Y. Here is the circuit: Exported circuit with annotations (Import & Simulate in ).

In my inexperienced attempt at scrapping this circuit together, I have used two LT6550 chips and Linear's application note. Now, the converter I am working on needs to take this VGA signal and convert it to YPbPr to display on a CRT TV. This creates valid 15khz VGA that works with my VGA capture card for high quality video capture. From the game consoles, the RGB signal is taken from before the composite encoder chip and the HV sync signals are generated by a TI LM1881 chip being fed with composite video from after the composite encoder chip. Purely for hobby, I am working on an RGBHV (VGA) to YPbPr (Component) converter circuit for old games consoles modified to output RGBHV on a VGA cable.
