8K TV and 5G: Game changers in home entertainment

The 8K resolution television and 5G were the two main themes of the Consumer Electronics Show (CES) in Las Vegas last month.

The 8K resolution TV was first launched at CES in 2012, but lacked software and content back then.

Now, several TV makers are already mass-producing big screen TVs from 75 to 200 inches. I believe they will soon become more affordable.

In the next few years, we should also see more movie makers producing films using the 8K standard.

A broadband connection with a speed of 25 megabits per second is required for 4K streaming. On the other hand, an  8K TV may need a network speed of 80 to 100 mbps. That should not be a problem in the optic fiber network era.

In fact, Japanese TV networks have already launched 8K trial broadcasting.

At the Winter Olympics in Pyeongchang, South Korea last year, 5G live broadcasting made its worldwide debut, showing real-time, 360-degree video of athletes competing in the games.

It is reported Japan intends to use 5G technology for live broadcasts in the 8K format in the Tokyo 2020 Olympic and Paralympic Games.

Home entertainment is set to see some game changers in coming years.
