They put the chroma subcarrier at around 1.5Mhz and mixed it in with the video luma, and the player upconverted it up to 3.58MHz after using IIRC a line comb filter. The luma resolution was about 3Mhz, better than VHS tape, but worse than laserdisc (4MHz).

So, it's not composite like LD. I wonder if an S-video output could be added?
