Digital broadcasting is the practice of using digital signals rather than analogue signals for broadcasting over radio frequency bands (radio broadcasting). Digital television broadcasting (especially satellite television) is widespread.[citation needed] Digital audio broadcasting is being adopted more slowly for radio broadcasting where it is mainly used in Satellite radio.[citation needed]
Digital links, thanks to the use of data compression, generally have greater spectral efficiency than analog links. Content providers can provide more services or a higher-quality signal than was previously available.[citation needed]
It is estimated that the share of digital broadcasting increased from 7% of the total amount of broadcast information in 2000, to 25% in 2007.[1][2] Some countries have completed a Digital television transition.[citation needed]
