This year, the TV station moved one step further and utilized 5G to transfer 4K video between the four venues.
The 2019 chunwan is performed in four different cities, namely Beijing, Shenzhen, Changchun and Jinggangshan. Each venue is located hundreds of kilometers away from the others, making it hard to transfer video between them in real time.
According to data from Beijing Business Daily, more than half the families in China have 4K TV sets, meaning more people can enjoy chunwan in 4K while people are still watching the Super Bowl in 1080p.
Other new video technologies like 10-bit color depth and high dynamic range (HDR) were also introduced to chunwan last year with the aim of displaying colors more accurately.
Though most smartphones cannot display 4K video, mobile users can still benefit from these new technologies.
CCTV streamed the 2019 chunwan online with a 50fps channel, which contains twice as many frames per second as a standard PAL format video. For an example of this, check the slam dunk gif at the top of the page.
