Since a couple of years the term digital tv has been heard in the market but many of the users still do not have a clear idea about it. This is basically a technology which allows the user receive and send footage, which is synced by an appropriate sound. This sound possesses digital signals as compared to analogous which were used earlier. Today most of the countries have turned of their analogous signals because Digital TV has been proved better on the technical standards. In addition to that, it has been able to gain acceptance in the market easily.
Although it has a lot many characteristics which makes it have an edge over others but still its compatibility with various picture formats is highly appreciated. These formats are supported irrespective of their size, aspect ratio and much recently interlacing. Constant growth witnessed in terrestrial broadcasting in various countries has led to the introduction of two sub formats of this technology, which are known as HDTV and SDTV.
Compatibility of HDTV with various formats is well known and implementation of many applications along with aspect ratio is taken into account by SDTV. Digital TV is divided into sub channels and provides multiple feeds. Occurrence of current convention bandwidth is one of the major reason behind this particular fact.
There are many methods through which the user can avail the facility of a digital TV. Firstly the antenna because it is one of the easiest and cost effective way to get a digital signal. It is also known as Digital terrestrial network as well. Secondly, the digital satellite and cable can also be used for the same purpose. Other than these two methods some of the well known applications through which this technology can easily be accessed are DVBH, IPTV and DMB. Although this technology entitles the user to have an overview of the best applications but one thing should taken into consideration for the protection purpose. This one parameter would be that these signals should not interfere with others because it tends to hamper the footage being broadcast.
Along with all the unique features, Digital TV has some more advantages. Firstly it would be the pickup of a less bandwidth, secondly, the provision of more signals in the given space and finally some special services like electronic program guides, some additional languages and multiplexing. Every Technology has its boons and banes and Digital TV is also one of them. One of the biggest limitations of this technology is that it has a lot of picture defects and artifacts, which are compressed. Along with it algorithms have made the users encounter many problems. Other than these two, the presence of multi- path interference has led to a poor reception. If all these limitations are ignored than then technology could not be better than this.
