DVB-T is a technical standard for digital terrestrial television broadcasting that specifies framing, channel coding, and modulation. It is used in over 40 countries with nearly 200 million receivers sold, mostly in Europe. Benefits of DVB-T include better quality TV, improved population coverage, spectrum efficiency allowing more channels, and enabling HDTV and reception on mobile devices. Key issues in deploying DVB-T networks include establishing appropriate legal and regulatory frameworks, network planning, and content distribution infrastructure.
