4k resolution - description of the standard

The Japanese concern NHK has developed the UHDTV standard for the telecommunications sector. It was adopted in 2012 during meetings of the International Telecommunication Union.

The maximum resolution was 3840x2160 pixels. It became known as Ultra HD. Television screens have been able to achieve widescreen aspect ratios. It became equal to the 16:9 position. Today, this standard is one of the most frequently encountered and purchased. In the film industry, it is called 4K due to the fact that the frame width of the frame has become 4000 pixels. It's interesting that television producers don't think of stopping at the achieved result.


Standard resolutions

To understand ultra-high definition video, you need to imagine a 15-meter screen. The picture on it will remain with the same clarity as on a standard television screen. The digital cinema projector only supports 2k resolution. Quadruple format support is available on IMAX. Translated from marketing English, this is the maximum type of image. The standard uses multiple projectors with quadruple resolution.

4k implies absolute clarity and detail of the image, transmitted brightly and richly. The density and realism of the image increases due to a decrease in pixel size and an increase in their number. As a result, objects become more detailed in outline and can be seen better.

Compared to 2k, 4k offers improved frame rates, color depth, and audio quality. UHD applies frame rate. Color has a depth of 12 bits, and color coverage is 75%. The screen reproduces about 69,000,000,000 shades of the color palette. For a better understanding, the top Full HD models change frames at a speed of 60 kiloseconds. Color is 8 bits and the color space covers 35% of the screen.

How to connect to these channels

To watch 4k, you will need to first acquire the following elements:

  1. TV . To fully enjoy this format, you need a TV equipped with a satellite tuner. Often these are models with a 48-inch UHD 4K Flat Smart TV HU8500 Series 8 screen. They are found in the LG and Samsung lines.
  2. Receiver. Standard receivers do not support this format. Of course, you can activate and configure it, but you won’t feel much change.
  3. Satellite dish and necessary elements for connection and installation.

You will also need the Conditional Access Module CI+ in combination with a smart card and the Unified package. It is this kit that will provide access to the necessary channels.

Which receivers support Ultra HD

At the moment, receivers supporting 4K Ultra HD are available in a limited range. The company offers its users the GS AC790 model. It supports the required format, although outwardly it is an unremarkable set-top box. However, if you carefully read the characteristics, the user receives a fairly functional device with a wide range of capabilities. At the same time, the GS AC790 is very inexpensive and very easy to set up.

You can get a similar model on favorable terms, with a decent discount. Tricolor TV, both in the past and now, is holding a campaign to exchange outdated receivers. Other models include Gigablue HD Ultra UE and VU+ Solo 4K. Also quite powerful consoles that support the desired format.

The difference between 4K and 2K resolution

High definition televisions have been a standard for decades. Today there are no television devices that do not display a resolution of 720p. “P” stands for progressive picture type. I is an alternative designated interlaced scanning. The odd and even lines are displayed alternately in each frame. This results in degraded image quality.

The term 4000 pixels is a display format that has a wide horizontal resolution. UHD is 4k. The difference is that it is more suitable for consumers and 2K television. As a result, DCI is considered a professional production standard, rated at 4096 x 2160 pixels. UHD is a standard with a resolution of 3840 x 2160 pixels. There is an 8k format at 7620 x 4320 pixels. It gives a flawless image.

Pros and cons of 4k resolution when used on TVs

4K resolution provides ultra-sharp picture detail due to increased pixel density per square millimeter of screen. The scanning frequency is 120 frames per second.

  3. TV can be watched at a short distance, this is due to the fourfold magnification of the screen image.

The advantage is that it is possible to place a TV in a small apartment with a modest room area.
