Image and video.
Let's start with image quality.
- Pixels, number of dots on the screen, usually in width x height.
- 1080p, an image resolution of 1920x1080 pixels.
- 4K (Ultra HD), an image resolution of 3840x2160 pixels.
- FPS, frames per second / number of frames per seconds.
- 8 or 10 bit color, quantity of colors.
- compression, video made smaller as a video file.
Below is an overview of image formats and resolutions;
You see 4K UHD 4 times more pixels than 1080p.
However, what is noticeable value?
If you assumes that all TV channels are broadcast in DVD quality and the most HD channels in 720p or 1080p and 4k will be an improvement. You will notice the difference between 720p and 1080p on screens 32 inches and larger, however, 4k compared to 1080, in many cases not even be noticeable. This is due to the distance at which you are viewing it.
Below you can see a schedule;
The white area shows where the difference is not noticeable, and the blue as well. You have a 50 inch TV is the only noticeable difference from two meters closer to 2 meters, you have been very good eyes to see the difference. You understand where this is going; How far you sit from your TV and how big is your TV?
FPS is the number of images per second that a device can render, or play, that you can compare the number of hertz TV. Standard for 1080p 60FPS today. are you for 4k, depending on the HDMI protocol (technique). He can HDMI version 1.4b You get up to 4k @ 30FPS with 8 bit color. From HDMI 2.0 could reach up to 4K @ 60fps 10-bit color.
The number of colors will indicate at 4k in bit, the higher the more colors can be displayed.
The above is all very well in theory, but there are some snags sit at!
A rough 4k film of 1 hour at 4k @ 60FPS with 10 bit color at the highest quality does not agree on a recent large hard disk. We can compress codec (software) such as H.265 HEVC to allow to make it smaller. To make 4k negotiable there will be much in quality must be screwed back, otherwise it will not save or stream to decent. A more reasonable quality encoded with HEVC to allow H265 will 4K films of an hour 23.976fps with 8 bit color still are large around 30GB, here is already well on quality curtailed which makes a comparison with proper 1080p at high quality hardly more real is. Of course, 4k more pixels have only 1080P of the same size will be smoother, with more detail in scenes faster and more detail in dark scenes.
4K streaming will provisionally not be readily affected by quality. First, there is virtually no 4k content. Secondly, it will not be feasible for ISPs to provide a 4K stream through the large amount of bandwidth that is used many users.
Do you want to stream? Then 4K nothing but a sales pitch, as yet far from feasible.
You want to play from your hard drive or NAS? Then 4K is an option provided you have enough storage space, and do not go from a small file, you will get the quality you expect. (30GB per hour movie in H.265 HEVC to allow email@example.comFPS 8 bit because it begins). To do this you must ensure that HECV supported'm by your media player. Please note that many films have this great remastered and its meaning that the movie was original 1080p and is converted to 4k 4k making the total value has disappeared. Please note that 4k with decent quality is many times greater.
The compression method HEVC to allow approaches streams becoming more common, so our advice is to take this into account. (Including HD streams) .All models now have the support to decode this.
Hopefully the explanation is not too technical but you understand it 4k a nice added value is only really practical use for the time being not yet in. If you have a 50-inch 4K TV, you sit 3 meters distance than 4K has no value anymore. Word 4k with 15Mb / s streamed then you should see a quality 1080p HD stream.
8K also comes into play again. What is the real value? Let you do not go crazy with all terms read everywhere. 8K will be on a screen of 60 inches at 50cm viewing distance only be noticeable with respect to 4k. First, let's decent stream 1080p before we start talking about 4k. Most streams get 1080p HD disagree, Your HD TV channels are 99% 720P and 1080P no!
In kodi / MinixMC most streams firstname.lastname@example.org and this is called HD content.
In the future, 4K streaming to come once but it still takes jaren.Laten we first try 1080p Full HD on a good quality to get inside.
4K, a great story, great sales pitch, but totally impracticable.
In brief: (For use at home)
The newer box is the box faster with the most potential, and therefore recommended if you want the better. Would you just watch a movie than a budget box is a great alternative. A budget box as x6 will be slower in responding to menus and programs but will also play extremely well streams 1080p content since most 1080p or lower. Neo U1 is currently the fastest of the MINIX satellite speakers and also has the most features such as HDMI 2.0 4K @ 60fps 10-bit and 7.1HD audio formats.
