Channel Change Gap

CIMM DEFINITION: During a channel change, the period of time between the display of one channel and the next. Depending upon the Set-Top Box either a black screen, grey screen, still image, flickering, or some combination may be displayed during this time, which may last from a small fraction of a second to many seconds. During this time, the viewer typically has no control of the Set-Top Box, and all inputs from the Remote Control are ignored, or queued for later execution. Appropriate editing rules must account for these gaps when providing second-by-second metrics. (Source: FourthWall Media)
