What is DPCM? As simple as possible.
In this video, I try to explain how DPCM or Delta PCM (or Delta Pulse Code Modulation) as implemented by the NES works. This is an overview of the compression method, and avoids diving deep into the technicalities of the implementation.
Correction: Kilohertz ("kHz") is more correctly written with a small "k", like kilogram ("kg")
