High definition television sets are the new types of televisions being manufactured and sold to the public. The term ‘high definition television’ refers to the clarity of the moving image you are watching. In a nutshell, the more detailed the moving picture is, the clearer it is, and as such, the moving picture is considered to be of a high definition.
To view a high def moving image however, you need to have a receiver which can output the moving image without compromising the quality of the picture, which is why high def television sets are very popular indeed, and in fact, growing in popularity.
The term ‘high definition’ originates from the late 1930s where a new set of televisions were manufactured to replace earlier systems that were basic technology that had very little resolution – as little as 30 lines.
As manufacturers created better technology for program makers to record moving images onto them, manufactures created better technology that would receive the better quality moving images without compromising the quality. As a result of this, we now have what is considered HDTV. As this term is not new at all (originating in the 1930s), you would be correct in assuming that the term HDTV refers to the technology of current times. In other words, the HDTV technology now will be different to the HDTV technology in the decades to come.
HD television sets are permanent, and has replaced analogue televisions indeed! Manufacturers have phased out the production of analogue televisions because they are obsolete. In fact, if you attempted to watch a television show on an analogue television set in certain areas in the UK, you would not receive a signal, unless you have had it adjusted for the ‘digital switchover’.
The digital switchover is when all televisions in the UK switches over to a digital signal, meaning the transmission of the broadcast will be in digital, and no longer analogue. This means an analogue television will not pick up the signal. If you have an analogue television at home and would prefer not to upgrade to a digital one, you will need to use a set-top box, which will then enable you to receive the digital broadcast signal. Unless purchasing a second-hand television, your new television will be digital! It being digital however, does not necessarily mean it is a high definition television. It simply means it is made to receive a digital broadcast.
HD television sets may seem expensive, compared to normal ones, but if you’ve ever seen a display of a high definition television you will be amazed at the clarity it offers.
The need for a HD television set is debatable. Some people like the grainy look of moving picture. However, if you are someone who preferred the look of a DVD movie to that of a VHS one, you should definitely considered getting yourself a HDTV for your home. For many people, there simply is no going back.
