The development and evolution of video streaming has had substantial impact on the sports broadcasting industry , which is directly correlated to the emergence of high-definition (HD) and ultra-high-definition (UHD) live streaming. Live streaming of video sporting events may be attractive for broadcasters because viewers may typically tune into a live event and then watch the streaming version of the event at a later time  to watch the entire event, follow the action in the event, or watch the game on a mobile device. The emergence of live streaming has had a substantial impact on the revenue of the National Football League (NFL), which saw a $2.89 billion increase in revenue from 2010 to 2012 . Qualified broadcasters and third-party vendors have the means of creating video compression techniques for live video broadcasting, and manufacturers of video-based display devices must decide whether to adopt a format that is ready for widespread streaming uses or continue to support a proprietary deployment of a selected video coding technique.
After the wide adoption of 3D televisions in the late 2000s, the need for 4D television technology arose in sports broadcasting. Both sports leagues and broadcasters began to work to incorporate 4D technology for broadcasts of live sporting events. d2c66b5586
