Clean feed (television)

Generation of both Program and Clean Feed. The *clean* signal has no graphics keyed over it.

In television technology, a clean feed is a video signal that does not have added graphics and text. This video signal is used in sport production to allow different

news broadcasting to produce two or more different streams, each one with the same picture but in different languages.^{[citation needed}

A clean feed is a signal which has not come from the main output of the

keyer

stage - the clean feed is identical to the main program output but without any captions keyed into it. Modern production equipment can actually put different keys on multiple outputs, allowing them to go to the clean feed or not. The most sophisticated vision mixers (or production switchers, according to the American nomenclature) can generate a clean feed output for any of their mix/effects (ME) buses.

The term clean feed is also used to refer to

lower-third graphics or superimposed chyron

text.
