Image noise is interference in the video signal that shows up as grainy specks. It can be caused by low lighting situation, a nearby power interference, heat, or device algorithms DNR is a technique of removing image noise from a video signal by applying a digital comb filter. It makes images clearer and reduces video file size.

Term used to define the direction of data transmission between two parties. Half-duplex allows data transmission in both directions but not simultaneously. Full-duplex allows simultaneous data transmission.
