Digital TV DTV has several advantages over analog TV, the most significant being that digital channels take up less bandwidth (and the bandwidth needs are continuously variable, at a corresponding reduction in image quality depending on the level of compression as well as the resolution of the transmitted image). This means that digital broadcasters can provide more digital channels in the same space, provide high-definition television service, or provide other non-television services such as multimedia or interactivity. DTV also permits special services such as multiplexing (more than one program on the same channel), electronic program guides and additional languages, spoken or subtitled. The sale of non-television services may provide an additional revenue source.
Digital signals react differently to interference than analog signals. For example, common problems with analog television include ghosting of images, noise from weak signals, and many other potential problems which degrade the quality of the image and sound, although the program material may still be watchable. Digitized signals are designed to resist ghosting or noise by using a redundant signal composed of numeric codes. Even if some of the information is missing or wrong, the decoder computer can reconstruct the complete signal. The only way it fails is when the decoder does not receive enough information from the antenna -- if there is too much interference in the signal for the decoder to read enough of the numbers and produce the picture. This can render a digital signal completely or partially unwatchable (picture pixelates or freezes) in situation where an analog signal would still be usable, in urban (ghosting due to multi-path) and rural (weak signal) areas.
Get Ready For Digital TV
In the United States, where most full-power television stations are already broadcasting both an analog and a digital signal, the FCC has set June 12, 2009 as the date on which all analog transmissions will cease and over-the-air broadcasts will be solely digital. By special dispensation, some analog TV signals ceased, as previously scheduled, on February 17, 2009 and earlier in Hawaii. However, US President Barack Obama delayed the introduction of digital TV in most areas as part of an economic stimulus package so that the switch occurred on June 12, 2009.
There are a number of different ways to receive digital tv (digital television). One of the oldest means of receiving Digital TV (and TV in general) is using an antenna (known as an aerial in some countries). This way is known as Digital Terrestrial Television (DTT). With DTT, viewers are limited to whatever channels the antenna picks up. Signal quality will also vary.
