To maintain the purity of the signal, Sony places the analog video circuitry on a separate board, driven by its own power supply.
Because digital noise can corrupt the DC voltage, the power supply is another potential path of interference. That's why early on, Sony recognized the advantage of giving the analog circuit block its own series power supply. This ensures power that's both abundant and clean.

DVD players process analog audio, analog video and digital signals in close proximity, opening up the possibility of signal radiation and interference even between circuit boards. To prevent even slight traces of interference, the
To minimize signal interference, the
