What are the "4K" and "8K" TVs you often hear these days?
Hello.
Last time, we introduced recommended Christmas gifts, but did you use it all?
Christmas is over, and it has only been a few days this year. How do you spend the year -end and New Year holidays? This year, it's a corona, so many people spend time watching TV slowly at home? So, this time, I would like to study about "4K" and "8K" TVs that I often hear recently. Recently, you often hear the term "4K" and "8K" TV. But what are "4K" and "8K"? Can you explain it properly?
What is "K" of "4K" and "8K" in the first place?
"K" is a term that represents 1,000, which refers to "4,000" and "8,000". If you compare it by weight, think of it as the same relationship as "4000G" = "4kg". In the case of TV, "4,000" and "8,000" are the number of pixels in the horizontal (horizontal) direction, and the standard of around 4000 x 2000 is called "4K" and the standard of around 8000 x 4000 is "8K". increase.
On the other hand, the current terrestrial digital broadcasting, satellite broadcasting, and TV receivers are called "full HD" of 1920 x 1080 with horizontal x vertical pixels. This is often called "2K" since "4K" and "8K" appeared.
The difference between "2K", "4K", and "8K" is the difference in the number of pixels that make up the screen. 2K is 1920 x 1080 = 2 million pixels, 4K is 3840 x 2160 = about 8 million pixels, 8K is 7680 x 4320 = about 33 million pixels. In other words, if the same screen size is 4K, the pixels are 4 times higher density than 2k, and for 8k, the 16x video of 2k is precise.
Full Hi -Vision (2K), 4K, and 8K have the following differences when approaching the TV screen.
By the way, terrestrial digital4KBroadcasting, when did you start?
From December 1, 2018, 4K8K broadcasting started on satellite broadcasting using BS/110 degree CS.
However, it is 4K broadcast of the essential terrestrial digital digital, but this is the same as the current situation. The same full high -definition (2K) broadcast will continue.
Why don't you broadcast the ground digital 4K?
The terrestrial digital broadcasting is the center of television broadcasting, and most of them can be easily viewed by anyone without a lot of money. It has a role to deliver not only weather forecasts and news, but also disaster information such as earthquakes and tsunamis, important notices from the government. If terrestrial digital broadcasting is changed to 4K or 8K broadcasting, it is necessary to buy a new TV in all homes as at the end of the analog terrestrial broadcasting in 2011, which causes a major confusion. For this reason, terrestrial digital broadcasting will remain the current full high -definition broadcast (2K). Please be assured that there will be no sudden disappearance of terrestrial digital broadcasting one day.
summary
With the spread of 4K TVs is being promoted, it is thankful that TV broadcasting will be 4K so that you can enjoy higher -quality programs. The 2021 Tokyo Olympics are also included in 4K and 8K cameras, so you can enjoy sports festivals with more realistic images (although it is a story if it is held). If you already have a 4K8K TV, please take a look at the new 4K8K satellite broadcasting. There is no doubt that the difference in the cleanliness of the screen will be surprised!
Unfortunately, terrestrial digital broadcasting has no plans to convert to 4K at the moment, but conversely, there is no such thing as being forced to replace the TV, so it seems that it does not hurt (laughs).
If you want to enjoy the New Year's program on a small TV that you are watching now, you should buy a new one at this opportunity!
