Digital TV has provided a host of important public benefits:
It has freed up parts of the broadcast spectrum for public safety communications (police/fire/rescue).
It has allowed some of the spectrum to be auctioned to companies that will be able to provide
consumers with more advanced wireless services (such as wireless broadband).
It has allowed stations to offer improved picture and surround sound (enhanced audio).
It has expanded programming choices for viewers. For example, a broadcaster can now offer multiple digital programs simultaneously (multicasting).
It has provided interactive video and data services that were not possible with analog technology
Difference Between Analog and DTV Broadcasting:
DTV is an advanced broadcasting technology that replaces analog over-the-air broadcasting. Digital broadcasting allows stations to offer improved picture and sound quality along with a host of other advantages over analog broadcasting.
For example, rather than being limited to providing one analog program, a broadcaster is able to offer a super sharp High Definition (HD) digital program or multiple Standard Definition (SD) digital programs simultaneously. Digital television offers many advantages over analog television for viewing broadcast TV
Need for DTV Picture Reception Over-The-Air:
need one of the following:
If you have a digital TV set, you will not need any additional equipment (with the exception of an antenna) to receive over-the-air digital broadcast programming. However if you have an analog TV set, a digital converter box must be connected between the antenna and the analog TV to receive and display over-the-air digital programming
