Digital television Digital television (DTV) is the transmission of television signals using digital technology, as opposed to the traditional analog signals used in analog television. DTV offers several advantages over analog television, including improved picture and sound quality, more channels, and additional features such as electronic program guides and interactive content. It also allows for the transmission of high-definition (HD) television signals. DTV can be received through various means, including over-the-air broadcasting, cable and satellite television, and internet streaming. In many countries, analog television signals have been phased out or are in the process of being phased out in favor of digital television.
