Viewing television nowadays is certainly different from the humble experience it was in the early years under John Logie Baird to the vast array of images now viewable on the amazing Liquid Crystal Display (LCD TV) sets of today. It has now become almost impossible for most people to do without TV.
So having established where and when television arrived in our daily lives, just what exactly is TV and how does it achieve the things that it does do if that is not too technical a description (joke)? The word television is derived from a mixed usage of Greek and Latin roots meaning in literary terms �far sight� and being derived from the Greek term �tele� meaning �far� and the Latin �vision� meaning �sight� or �to view in the first person�.
As in most industries, along with technological development and innovation has arisen a large range of technical descriptions and phrases that if the truth be known confuses most people.
Perhaps it would be best now to move on to the latest developments within the industry and concentrate our coverage upon digital television, what it actually means; formats, bandwidth and an explanation of the technical jargon and terminology used.
How would we define exactly what Digital TV is? Digital television is a telecommunications system for broadcasting and receiving moving pictures and sound by means of digital signals in contrast to the more established analogue systems which is effectively the transmission of signals used by analogue (traditional) TV.
How does Digital TV differ from an analogue one? Using one of the newer LCD TV�s available will help us actually go through what all of this terminology actually means.
The LCD TV that we shall use for our illustrative purposes here is the Hitachi 32LD9700 LCD TV.
It is essential that we are familiar with the following key items of information.
The Screen resolution of the TV is possibly the most obvious place to start. Here we refer to the exact number of pixels that can be displayed in each dimension.
Whether the TV is Hi-Definition Ready would be the next thing to look at. By Hi Definition Ready we mean that is the TV is ready and suitable to take advantage of the latest Hi Definition TV pictures that more and more programmes are being broadcast in.
We would need to look next at what types of connectors are used to connect the various peripherals that go to make the entire Digital Package work.
We are referring here to the exact nature and number of the Scarts Sockets and Plugs in use. Here the definition of SCART refers to �Syndicat francais des Constructeurs d�Appareils Radio et Television (SCART).
Lastly on the technical side we would need to look at what types and what numbers of High-Definition Multimedia Interfaces (HDMI) are being used. Here High Definition Multimedia Interfaces (HDMI) refers to the audio/video connector interface that transmits the uncompressed digital streams of information between two or more digital components such as a HD DVD Disc player, a Blu-ray Disc player, a Personal Computer or Video Console.
The 32LD9700 is a 32in LCD TV and the prices for these are around 1000 pounds sterling or 2000 US dollars. The resolution of the screen is 1366 X 768 and with regards to being HD Ready the answer is yes. The Hitachi has 3 (2 RGB) scarts and the type and number of Multimedia interfaces the 32LD9700 uses is HDMI and 2. The type of Tuner for this TV is Analogue and Digital and the Hitachi is available from a wide variety of outlets.
All these points being taken into consideration, how would we view the Hitachi 32LD9700?
The most obvious place to start with as far as TV's are concerned would be the picture quality and our score here would be 10, and closely tied in to the picture quality is the sound quality and our score for this would be 10. Taking a look at the number of relevant connections and their availability, our score would be 8. As far as overall features are concerned we would give it 10 and for ease of use and overall value for money we would give it, 10 and 10 respectively.
The overall verdict would be WOW what can you say but that this is one of those TV's that excel in almost every thing it is supposed to do. Described as a "Superb All-rounder", there is not much that this TV does not achieve. If you can get your hands on one of these then go for it.
Please bear in mind the prices that are quoted in this article and take note that they are there purely for illustration and though valid at the time of the writing of the article may vary from time to time and also depending on the time of year when you make your purchase.
