Concept
Outside broadcasting
Summary
Outside broadcasting (OB) is the electronic field production (EFP) of television or radio programmes (typically to cover television news and sports television events) from a mobile remote broadcast television studio. Professional video camera and microphone signals come into the production truck for processing, recording and possibly transmission.
Some outside broadcasts use a mobile production control room (PCR) inside a production truck.
Outside radio broadcasts have been taking place since the early 1920s and television ones since the late 1920s. The first large-scale outside broadcast was the televising of the Coronation of George VI and Elizabeth in May 1937, done by the BBC's first Outside Broadcast truck, MCR 1 (short for Mobile Control Room).
After the Second World War, the first notable outside broadcast was of the 1948 Summer Olympics. The Coronation of Elizabeth II followed in 1953, with 21 cameras being used to cover the event.
In December 1963 instant replays were used for the first time. Director Tony Verna used the technique on the Army-Navy game which aired on CBS Sports on December 7, 1963.
The 1968 Summer Olympics was the first with competitions televised in colour. The 1972 Olympic Games were the first where all competitions were captured by outside broadcast cameras.
During the 1970s, ITV franchise holder Southern Television was unique in having an outside broadcast boat, named Southener.
The wedding of Prince Charles and Lady Diana Spencer in July 1981 was the biggest outside broadcast at the time, with an estimated 750 million viewers.
In 2008, the first 3D outside broadcast took place with the transmission of a Calcutta Cup rugby match, but only to an audience of industry professionals who had been invited by BBC Sport.
In March 2010, the first public 3D outside broadcast took place with an NHL game between the New York Rangers and New York Islanders.
The first commercial ultra-high definition outside broadcast was a Premier League game between Stoke City v West Ham, televised by Sky Sports in August 2013.
