Jargon Explained #1
Every industry has its own 'buzzwords' and jargon. Here we thought we would explain a couple of them, the differences, where appropriate, and their benefits and uses.
A High Definition (1080p) picture has more pixels per square inch than a Standard Definition (SD) picture, with 1920 x 1080 pixels, meaning that the picture is better.
4K (which is also known as Ultra High Definition - or UHD) has a higher resolution than 1080p High Definition. 4K resolution is exactly 3840 x 2160 pixels. The name 4K is derived from the close to 4000 horizontal pixels.
So the more pixels, the clearer the picture.
Whilst 4K is not currently being broadcast on terrestrial channels, Netflix and Amazon video can stream films in 4K but a fast broadband speed is required. Sky also has some programmes available in 4K but require a subscription. 4K DVD players are available to play 4K DVDs and they can play all your existing DVDs as well.
