A set-top box called a TV converter box can convert free digital TV broadcasts into analogue formats for TV sets with analogue inputs. The device converts HD and SD digital broadcasts into analogue signals. The converter box may have an “analogue pass-through” function, allowing viewers to switch between analogue and digital broadcasts. Approximately 7,000 low-power TV stations in the US were exempted from the digital switchover requirement in 2009 and use the converter box to transmit broadcasts. Cable companies offer a similar set-top box for basic cable services.
