Outside broadcasting

[13] 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.

[14] 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.

[16] 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.

[20][21] 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.

Modern applications such as hardware and software IP codecs have allowed the use of public 3G/4G networks to broadcast video and audio.
