Xiao Bian had an opportunity to visit the electric city. After being pulled into the television area, the salesman blew up the TV 4K function. But users who don't understand, bought the TV home and said good 4K?
What is a 4K TV? A 4K TV refers to a TV with a resolution of 3840×2160 pixels. Its resolution is 4 times that of a 2K TV. At this resolution, viewers will be able to see every detail in the screen. A close-up, get an immersive look and feel experience. So the arrival of 4k gives people more visual experience. The first 4K TV on the market is a 55-inch product introduced by Toshiba at the end of 2011. Then Skyworth, Coolo, Changhong, Hisense and other companies launched 4K televisions.
From the perspective of resources, China's current cable digital set-top boxes are still economically backward in many places. Taking the three or four cities, the current resources of digital boxes are standard-definition and high-definition, and Xiao Bian has once handled HD set-top box services. Hearing people loudly show off their own homes, they use smart 4K TVs. But you have to know that the resolution of the HD set-top box is only 19201080, which is still a bit of a gap for 4K. No wonder someone said that the 4K effect is not as good as that of the old TV. The truth is that high-definition data is played on the 4K platform, and the HD image quality will be magnified, so you can imagine a 1920×1080 zoom to 3840×2160 pixels. So look closely and you can see that the picture quality will appear different.
To make 4K TV truly applicable, more still rely on the network platform to provide 4K resources, but the need is to improve the efficiency of broadband transmission, to achieve 4K picture quality, such as the transmission of 1 4K TV at least requires more than 50M of bandwidth, from the current China Most of the local networks are relatively backward, and more bandwidth is only 20M is slowly popularizing.
Therefore, it may take more time for 4K to fully spread throughout the country, such as the layout of the network, the production of resources, and investment in equipment.
