A flicker or fluctuation in a transmission signal or display image. The term is used in several ways, but it mostly refers to a loss of bits in a network transmission, which causes a momentary blip in a voice/video call or video stream.
In video streaming, jitter is more noticeable on a large screen than a small one, thus higher frame rates in the TV are more beneficial on a 75" screen than a 43" screen. See
frame rate.
To Jitter on Purpose
