A legislature broadcaster is a broadcaster, a television channel or a radio station that mainly broadcasts sound or video from the legislature and other parliamentary chambers such as parliamentary commissions in a city, state or in a country.
They can be either owned by the legislature chamber itself such as Europe by Satellite owned by the European Commission, Sansad TV, or the Knesset Channel; the country's public broadcaster like BBC Parliament or ABC NewsRadio; or a private company like C-SPAN or CPAC.
When the chamber is down or on holiday, either the channel goes down or other public affairs programming is broadcast.
