The HD Revolution is Upon Us.

Technology is changing at a rapid rate. I remember the good old days where you would simply have your television, perhaps a VHS player (simply called an VCR in the day) and that was pretty much it… not mentioning the wireless…I mean stereo system. Now as technology has changed most homes have a multitude of applications that all do weird an fantastic things. The basis of these are your LCD television, your DVD player, your VHS Player (I still have many videos that I can’t stomach getting rid of!), your computer games console…and so on. With all of these appliances you have a mound of spaghetti that is the cables powering and connecting all these things together. If there is one cable in amongst the whole mound that you should have by now though it is the HDMI Cable!

Let’s all face it the high definition revolution is upon us now and we have to begin to embrace it. We are being bombarded with TV adverts, radio adverts, bill board adverts and even on the internet telling us to get a HD TV or sign up to Sky HD – there’s no way of escaping! But although it will be a few years until this HD revolution fully takes over it is still worth considering getting it now if you have the dosh.

HD really does look the business and if you need convincing then get yourself down to your nearest electronics store. But seen as you are reading this anyway I may as explain a bit why HD is so good and be warned I’m about to get a bit technical here…

In its most basic of explanations I shall compare a HD TV with that of a standard one. Standard TVs known as standard definition televisions have a almost square picture with a ratio of around 4:3. The pixels (which is the number of tiny dots that make up the picture) is roughly 704 x 480. The picture was interlaced which means that each piece of the moving images was really half a picture and the pictures changed so quickly that the brain did not register this. Also standard definition TVs relied on analogue signals.

HDTVs are digital and use information in the form of ones and zeros. The information travels through cables as electrical pulses and the aspect ratio is 16:9 – a lot higher than standard definition. The resolution is also much higher with 1920 x 1080 pixels and the picture is the whole thing rather than half an image unlike its predecessor.

Due to the wider screen and the more pixels and the fact that HDTVs can display more colour HDTVs need more data and need it fast compared with standard definition TVs and this is where the HDMI cable comes into play.

HDMI cables allows for a high bandwidth connections between digital devices and with the correct set up can make a huge difference to your home-theatre system. HDMI cables can cut down on the number of cables –ridding you of the spaghetti problem- and can also reduce the number of remote controls you need for all the appliances.

Before you run off and start buying your home theatre system you have to make sure that all the appliances are compatible with HDMI. Also when buying the cable make sure you buy the correct length as many people by shorter cables thinking they are saving money but then find out that they can’t connect their home theatre together.

I won’t continue but will rather let you check out what HD has to offer yourself. Of course standard definition does the job fine but I must say that there is nothing better than seeing England score a goal and feeling like you are there…then again this rarely happens!
