Digital broadcasting is the practice of using digital signals rather than analogue signals for broadcasting over radio frequency bands. Digital television broadcasting (especially satellite television) is widespread. Digital audio broadcasting is being adopted more slowly for radio broadcasting where it is mainly used in Satellite radio. 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.

| - デジタル放送（デジタルほうそう、digital broadcasting）とは放送局により行われるデジタル方式の放送のことである。通常のアナログ放送と同様の電波帯域を使い、アナログデータの代わりにデジタルデータを伝送する放送である。 日本においては、狭義には「デジタル方式の無線局により行われる放送」を言う（電波法施行規則第二条第一項第二十八の十六号）。広義には、デジタル方式により行われる放送全般、すなわち1990年代以降の、アナログ放送と同様に音声・映像などのマルチメディアデータを一定の規格に基づき放送するサービスを意味する。 最広義にはIPを利用したインターネット放送（インターネットテレビ、インターネットラジオ、IP放送）まで含まれうるが、本項では除外する。 (ja)

Digital audio broadcasting is being adopted more slowly for radio broadcasting where it is mainly used in Satellite radio. 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. 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. Some countries have completed a Digital television transition. (en)
