What is the digital TV antenna?
Digital TV antenna is a TV antenna that allows you to receive digital air signals. It is a similar analog antenna because it interprets the signals it receives to give you TV entertainment and media. However, digital signals generally provide a clearer picture and the TV is no longer sent via analog signals.
The traditional analog antenna or "rabbit ears", as they were sometimes called, were used to pick up analog RF signals in the air. The antenna could get information and display TV programming. Digital antennas are essentially the same function, but the information they receive are transmitted digitally and not with analog RF signals.
The digital TV antenna can be connected directly to the TV. However, it must be able to pick up a digital signal, so the signal must be available from the satellite or from another source of digital programming, such as the local broadcast station. Digital TV antenna can be attached to the roof of the housewhere he has access to a digital signal.
To transfer TV programming to television, the TV must be able to decode the digital signals that receive from the digital TV antenna. All TVs produced and sold after February 2009 have the ability to decode built -in digital signals. TVs produced before 2009 may or may not be able to receive signals from the digital TV antenna, depending on whether TV has a digital converter or not.
To ensure that everyone has access to digital TV is available converters. These converters allow people with old analog TVs to still receive programming through the antenna, although all programming is not distributed in digital format. The boxes convert digital signals to analog signals that your old TV can understand.
Change to Digital TeLevis broadcasting, unlike traditional analog broadcasting, came into force in February 2009. The government wanted to change from digital to analogue television to release radio frequencies for other military and other use, since only a limited amount of data can travel along analog signals. Consumers were for digital television because digital TV provides a clearer picture and other features.
digital television should not be confused with high -resolution television. While most digital signals are broadcast in high definition, the digital television antenna itself is not enough to ensure access to high -resolution TV. TV must also be able to display high -resolution digital signals with high -resolution to give you a high -resolution television antenna.
