Digital tv in India has come a long way from occupying a niche market to becoming a popular feature in almost all homes and commercial complexes. Of course, the mind-boggling array of features that it comes with and the sharp, precise output that one gets to experience has contributed heavily to its growth. Other advantages of the same include easy portability and installation, good service, powerful signal and of course good after-sales service.
What is the digital TV
Strictly speaking, it is just an alternative method for the broadcasting of sounds and images as they appear on any television screen. The difference lies in the broadcasting wherein signals are sent in the form of discrete pieces of information rather than as continuous analogue ones. This enables it to do away with the problems of snowing and ghosting and improve the picture quality. This difference in picture quality and good quality of output can best be experienced in 32 inch tv and higher since transmission of the signals for digital TV is best done through satellite and radio-communications. Of course, it can also be transmitted through broadband or cable network but there is a distinct difference in quality.
Benefits of Digital TV
The transmission of digital TV is much more efficient and flexible than an analogue system. Thus viewers are treated to a wide range of services which are both new and different. Some common benefits and services offered by digital TV are:
- Reception is ghost-free with selected programs even allowing multiple cameras views with enhancements,
- Widescreen picture ratio of 16:9 for both standard and hi-definition television,
- Enhanced audio quality with surround sound,

There are other several types of services which can also be provided with the help of digital TV like interactive services and programs, internet services, computer games, home shopping etc. But in order to get the best experience out of the digital TV, it is always better to view the output in the latest HD TV.
Digital TV output in standard and hi-definition television
Each picture formed on the screen is made up of pixels or numerous small dots. It thus goes without saying that the higher the number of pixels, the better is the picture quality. In a standard definition TV, the output is characterised by a maximum horizontal resolution of 720 pixels and a maximum vertical resolution of 576 pixels. They can thus be considered to be the digitised version of broadcasting on a conventional analogue television.
Hd tv India, on the other hand, is characterised by a horizontal resolution of at least 1024 pixels and a vertical resolution of at least 720 pixels. The display is also on a wide screen with a ratio of 16:9. In addition to this, they also support features like a multiple channel sound system so as to enable HD TV viewers a cinema-like experience but in the comfort of their homes.
The led tv price is relatively more than that of a conventional television but for a cinema-like viewing experience, it is always better to opt for the LED TV which supports high definition broadcast. An LED TV also enables the viewer to get value for money when used with a digital TV.
