Digital Tv What You Need To Know

Digital Tv What You Need To Know



Digital TV – What You Need To Know.
Digital TV is​ on it’s way .​
Do you know what you need to​ do? Are you prepared? Find your answers here.
Your traditional television is​ known as​ an​ analog (analogue) television .​
It works by encoding the​ picture and​ sound information as​ an​ analog signal .​
The picture on an​ analog television is​ drawn on the​ screen one entire frame at​ a​ time .​
The analog signals are transmitted continuously even if​ there is​ no new information to​ send.
A digital television receives information as​ a​ digital signal .​
This is​ an​ entirely new technology and​ will eventually replace the​ analog television system.
The digital signals are transmitted using computer code, which consist entirely of​ ones and​ zeroes .​
This is​ a​ difficult concept to​ perceive but it​ works .​
Digital signals are much more efficient, result in​ less interference and​ therefore it​ provides a​ better quality picture and​ sound than analog.
Another significant feature of​ digital television is​ that is​ uses a​ significantly smaller channel bandwidth .​
This means there is​ more ‘space’ for​ other digital channels which will allow other non-television services such as​ pay-multimedia services, multicasting (more than one program on the​ same channel), electronic program guides and​ interactivity to​ be used at​ the​ same time.
Whilst digital television often has superior audio quality, image, and​ reception than analog, it​ is​ still in​ the​ early stages of​ development and​ there are still many advances needed.
As with most things in​ today’s modern society Digital Television comes in​ a​ couple of​ quality levels:-
Standard Definition TV (SDTV) – This is​ the​ basic level of​ digital television transmission .​
It has a​ quality similar to​ today's analog TV;
Enhanced Definition TV (EDTV) – This gives a​ better level of​ quality and​ includes Dolby digital surround sound;
High Definition TV (HDTV) – This as​ the​ name suggests gives the​ best quality digital picture and​ Dolby digital surround sound.
Currently, most TV stations in​ America are broadcasting digital and​ analog .​
This means that you can view your favourite TV shows no matter what type of​ TV you have .​
However, after the​ 17th February 2018 the​ full-power TV stations will no longer be able to​ broadcast in​ analog.
And if​ you have an​ analog TV you will not be able to​ view the​ shows unless you obtain a​ separate digital-to-analog converter box or​ a​ new digital TV.
The National Telecommunications and​ Information Administration (NTIA) will sometime at​ the​ start of​ 2018, issue qualifying households with $40 coupons towards the​ purchase of​ a​ converter box .​
For more information on how to​ qualify go to​ www.ntia.doc.gov.
Bear in​ mind though, that an​ analog TV connected to​ a​ digital converter box will display the​ digital broadcasts but not in​ full digital quality.
Digital TV will be (and is​ now) available over the​ air using a​ standard antenna or​ via digital cable or​ satellite .​
No matter how you receive your TV signal (satellite, cable or​ over-the-air), you will need the​ digital converter or​ digital TV to​ watch the​ programming.
