HD television has become increasingly popular in recent years as the technology has become more affordable and, crucially, more HDTV content has become available. HDTV users can now enjoy HD games, HD films on Blu-Ray discs, and Sky now have up to 60 dedicated HD television channels for viewers to choose from, including entertainment, films and sports.
So what is HDTV, and what is all the fuss about? HDTV stands for High Definition Television. It’s a new type of television, which displays images at a far superior resolution than traditional television sets. As a comparison, a regular UK TV broadcast is made up 768 vertical columns and 546 horizontal rows of pixels. Each pixel is a tiny coloured dot, which combined makes up your television picture. 768 vertical columns and 546 horizontal rows give a sum total of 419,328 pixels per frame. HD television broadcasts, on the other hand, provide a far higher resolution, typically ranging from 1280 x 720 – that’s 921,600 pixels – to 1920 x 1080 – which is 2,073,600 pixels. So you can see that the screen resolution is vastly improved.
