Today digital television represents a major change from analog television technologies that we have been acquainted with ever since the launch of television broadcast services. An advantage to having digital television is that it is relatively easy to customize the bouquet of channels and special programs that you would want to get on your television. All this has been made possible because the digital television technology allows the picture and sound date to be compressed (with very little or practically no loss of detail) to a small size while being transmitted. Special converter boxes at our end magnify this data to give us the HD television viewing experience.
Apart from improvements to picture and the quality of sound, digital television provides a choice of more entertainment options as a greater number of channels can be made available on the existing network the digital television can be enjoyed in the coming months on large flat screen televisions that give us the surround sound effect that could be achieved previously only with high end audio equipment. A parallel development in free digital television is the adaptability of technology using computers to compress signals for transmission in order to make efficient use of the bandwidth available for each channel.
All this has been achieved without any compromise on widescreen television that has an aspect ratio of 16:9, what this means for us as consumers of HD television technology is that we will be able to view images that better fills our field of vision. The 16:9 aspect ratio is therefore the minimum standard for HD television as this aspect ratio gives up to a thousand times more resolution than conventional television images. This provides a much sharper and more detailed picture on your television set.
Now let us analyze the social implications of the digital television technology. One of the primary trends that have been entrenched with the coming of digital television and HD television broadcasts is that the ubiquitous television set has gained primary importance in the world of electronic media. The service delivery of add on features like the delivery of programs on demand and services such as e-mail, internet access etc. will be some of the future utilities that you may derive out of your television set enabled with a converter box (in case you want to hold on to your old analog television for some more time).
The commercial businesses are also enthused with the potential of digital technology in televisions. This is because they can have tie ups with providers of digital television services and can offer value added services for free to subscribers of digital television packages. For example, your local pizza joint could let you order a pizza by using the television set as an order interface. So you have the option to choose the mode by which you would like to access the service that is offered by local businesses if you are a user of digital television packages. Digital television is starting to gain in popularity and you can get yourself the benefits of hi-definition TV by opting for a professional installation from the providers of digital television services.
