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 [1] and television ones since the late 1920s. [2] 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). [3]

After the Second World War, the first notable outside broadcast was of the 1948 Summer Olympics. [4] [5] The Coronation of Elizabeth II followed in 1953, with 21 cameras being used to cover the event. [6] [7]

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. [8]

The 1968 Summer Olympics was the first with competitions televised in colour. [9] The 1972 Olympic Games were the first where all competitions were captured by outside broadcast cameras. [10] [11]

During the 1970s, ITV franchise holder Southern Television was unique in having an outside broadcast boat, named Southener. [12]

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. [13]

New technology

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. [14]

In March 2010, the first public 3D outside broadcast took place with an NHL game between the New York Rangers and New York Islanders. [15]

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. [16]

Tests in 8K resolution outside broadcasts began to take place during the 2010s, including tests by NHK [17] and BT Sport. [18] The first public 8K outside broadcast in the UK took place in February 2020. [19] [20]

Modern applications

Modern outside broadcasts now use specially designed OB vehicles, many of which are now built based around IP technology rather than relying on coaxial cable. [21]

There has been an increasing rise in the use of flyaway or flypack Portable Production Units, which allow for an increased level of customisation and can be rigged in a larger variety of venues. [22]

In the past many outside broadcasting applications have relied on using satellite uplinks to broadcast live audio and video back to the studio. While this has its advantages such as the ability to set up anywhere covered by the respective geostationary satellite, satellite uplinking is relatively expensive and the round trip latency is in the range of 240 to 280 milliseconds. [23]

As more venues install fiber optic cable, this is increasingly used. [24] For news gathering, contribution over public internet is also now used. Modern applications such as hardware and software IP codecs have allowed the use of public 3G/4G networks to broadcast video and audio. The latency of 3G is around 100–500 ms, while 4G is less than 100 ms. [25]

<span class="mw-page-title-main">Electronic field production</span> Video production which takes place outside a television studio

Electronic field production (EFP) is a television industry term referring to a video production which takes place in the field, outside of a formal television studio, in a practical location, special venue or fitting environment. Zettl defines EFP as using "both ENG and studio techniques. From ENG it borrows its mobility and flexibility; from the studio it borrows its production care and quality control. EFP takes place on location and has to adapt to the location conditions... Good lighting and audio are always difficult to achieve in EFP, regardless of whether you are outdoors or indoors. Compared to ENG, in which you simply respond to a situation, EFP needs careful planning."

1080p is a set of HDTV high-definition video modes characterized by 1,920 pixels displayed across the screen horizontally and 1,080 pixels down the screen vertically; the p stands for progressive scan, i.e. non-interlaced. The term usually assumes a widescreen aspect ratio of 16:9, implying a resolution of 2.1 megapixels. It is often marketed as Full HD or FHD, to contrast 1080p with 720p resolution screens. Although 1080p is sometimes informally referred to as 2K, these terms reflect two distinct technical standards, with differences including resolution and aspect ratio.

A television production truck or OB van is a small mobile production control room to allow filming of events and video production at locations outside a regular television studio. They are used for remote broadcasts, outside broadcasting (OB), and electronic field production (EFP). Some require a crew of as many as 30 people, with additional trucks for additional equipment as well as a satellite truck, which transmits video back to the studio by sending it up through a communications satellite using a satellite dish, which then transmits it back down to the studio. Alternatively, some production trucks include a satellite transmitter and satellite dish for this purpose in a single truck body to save space, time and cost.
