Television standard definition SD is not a high-definition television. The SD is used aspect ratio format 4: 3. The improved standard HD aspect ratio (16: 9).

With a high-resolution standard TV, SD video signal uses a small bandwidth applied for broadcasting, and by a narrow stream of video data for digital transmission. The DVD is a video standard definition SD.

Standard video DVD

  • 720 × 480, 704 × 480, 352 × 480, 352 × 240 pixels (NTSC)
  • 720 × 576, 704 × 576, 352 × 576, 352 × 288 pixels (PAL)

High-Definition Television,  HDTVHD. Let’s just say that all video that is larger than 1280 × 720 is called high definition video. This format allows you to transfer a greater definition video signal with a resolution of:

  • 720p 1280 × 720p:
  • 1080i – 1920 × 1080i or 1440 × 1080i

To send such a signal, it is necessary to use a wider bandwidth but the picture quality compared to SD looks much nicer on TV. In this format, start broadcasting satellites, as well as broadcast terrestrial digital TV standard T2 (in part).

Full HD TV resolution


Full HD — the marketing name for the first time invented by Sony in 2007. It is used in the broadcast high-definition television (HDTV) and movies recorded on Blu-Ray and HD-DVD discs. It is customary to call an image or a Full HD screen if the resolution is 1920 × 1080.

4K UHDTV (2160p) resolution 3840 × 2160

8K TV resolution

8K UHDTV (4320p) resolution 7680 × 4320

In connection with the development of recording devices it has become possible to carry out shooting with such a resolution is planned that such panels will be mass produced in the years 2014-2016. Their advantage is the possibility of creating a giant TV with a diagonal of more than 5 meters and the possibility of high-quality video.

As a result, in 2016 Sharp released a 8K TV for mass sale. But only for Japan, Singapore and China.

Other TV manufacturers began selling 8K TVs only in 2019.

To record one hour of video in the 8K standard, without using codecs to compress files, you need 300GB of memory. Therefore, video format 8K is transmitted or stored in a compressed form, for this purpose various codecs are used.
