Recently, I’ve been re-watching my childhood memories of “Pokemon”, but the more I watch it, the more I feel it’s very unclear, even though it’s only a cartoon and I’m also tuned to the highest quality “HD”.
Not only that, I also found that there are many other TV series that I used to watch now seem to be quite crude in terms of graphics.
How did not feel it before, what is going on? So I asked the department’s technical boss, Brother Steel, and listened to him and realized…
Because the previous filming equipment is not developed, the resolution of the film is not high, just adapted to the small screen with low resolution of the old TV, so the clarity looks okay.
But the same clarity of the program, we watch from today’s large screen 4K resolution TV, the effect is definitely more blurred. For example, these two pictures below.
Why is the cable TV signal still unclear now?
Most users at home with a wired signal, the clarity simply can not reach 4K, and even 1080p clarity can not reach.
4K TV can play 4K ultra-high-definition video, but also can play poorer definition of analog signals, low grade signal put out as unclear. For example, you buy a sports car, in the highway can be 300 km, in the country roads and a small bread running speed is almost the same thing.
That is, the TV screen please not clear, but also depends on the source of the content, if the source itself is low clarity, then the playback of the picture clarity is very low.
The average user’s home TV is an external set-top box, now live programs up to 1080p, even if you can see the 4K channel programs, your home set-top box is likely not to support 4K decoding, play out the picture clarity will not reach 4K. so that the picture is blurred is quite normal.
How can I see a clear film source?
There is nothing that can be done about the cable signal.
But the newly bought smart TV, the system is self-contained content, and many have joined the 4K area, although the 4K content is limited by factors such as network bandwidth, and did not really reach 4K resolution, but at least 1080P, there is indeed a considerable increase in clarity than cable TV.
If you want to pursue higher definition, you can download 4K sources to the local, no bandwidth limitations, the picture compared to the online video effect will certainly be better, but now the 4K movies are easily dozens of GB size, or need to have enough download speed and large enough storage space at home, while the home 4K TV codec capabilities also have certain requirements.
Local 4K looks great, but it is still troublesome to search and download resources online, so consider a combination of 4K Blu-ray player + 4K Blu-ray DVD, which will break the bank, but the experience is definitely the best.
Using a 4K Blu-ray player, in addition to experiencing true 4K, you can also experience cutting-edge picture quality technologies such as HDR, wide color gamut, and 10bit color depth, but this raises the requirements of the TV by another notch.
