It should cover scan doubling VGA adapters like the Super Espectro and the Roy Justus VGA adapter, RGB to S-Video, RGB to Component video, and RGB to SCART. It should talk about timing, and how the signal get buffered when the scan lines are doubled, different types of video sync signals and how to convert between them, and the significance of the back porch and front porch pulse plateaus. It should also discuss NTSC vs PAL composite video signals and NTSC artifact colors and how having a black and white NTSC signal that transitions more than 160 times in a full scan line is interpreted as a color signal.
