In television technology, clean feed is a video signal that has no graphics and additional text. These video signals are used in sports production to allow different television stations to add digital graphic images on their own display on common signals, or in newscasts to produce two or more different streams, each with the same image but in a language that different.
The net feed is a signal that does not come from the main output of the video switcher, such as the output of the vision mixer before the downstream keyer stage - the net feed is identical to the main program output but without the information entered into it. Modern production equipment can actually put different keys on multiple outputs, allowing them to go to the net bait or not. The most sophisticated vision mixers (or production switchers, according to American nomenclature) can produce net feed outputs for their bus mix/effects (ME).
The term "net feed" is also used to refer to a television programming feed backhaul sent by communications or other transportation (such as a national fiber optic network) transmitted from another TV station or a remote television production truck at a location, which is not subject to advertising television or bumper damage, or in some cases, lower third graphics or superimposed chron text.
