Regardless of what your favourite programme is, or the purposes for which you watch television, a higher quality picture is always going to be welcome and sharper, clearer images make television viewing more enjoyable for everyone.High definition is one of the most recent technological offerings which has changed the quality at which television programmes are aired. Until fairly recently, television programmes were only available in standard definition (SD) but more and more programmes are now becoming available in HD, with satellite television providers dedicating whole channels to this new and improved broadcasting resolution.There are currently more than 100 HD television programmes to choose from, covering everything from news to education and sports to popular music. 2012 in the United Kingdom will see the switchover from analogue to digital take place therefore HD channels are likely to become even more widespread.HD television (HDTV) has been such a success because it offers a much higher quality of picture and sound when compared to analogue; colours are more vibrant, details are more intricate and the picture is crisper.This improved level of quality is made possible because HDTV uses more pixels to create the images that are seen on-screen. A standard resolution analogue television image in the United Kingdom is made up of 576 lines of pixels whereas a HDTV screen uses either 720 or 1080 lines, producing around five times more detail than its SD counterpart and thus resulting in higher quality images.HD broadcasts are particularly suited to flat screens, such as LCD and plasma televisions, so if you do not already have one then you could consider investing in a flat screen television in the future as your viewing experience should be greatly improved.Remember that by 2012 all television programming in the United Kingdom will be switched over from analogue to digital, meaning improved quality and increased choice for all television users and making it essential to have a digital television, if not necessarily a HD one.To enjoy the best of HDTV you need to have the correct programming, compatible connections and the right equipment which includes an HD ready television as well as a HD receiver. If you want to integrate high definition channels into your home using digital television or Sky+HD then you need to make sure your television set is HD compatible. The HD Ready logo appears on all television screens and projectors that are compatible with HDTV signals. HD Ready screens must also have a minimum of 720 vertical lines so look out for the latter figure when the resolution is written out, for example 1280 x 720.Once you are up and running on HD you should be able to see and hear the difference immediately and can continue to choose from an ever expanding selection of channels.
