Editing Digital television (section)

=== Reception ===
There are several different ways to receive digital television. One of the oldest means of receiving DTV (and TV in general) is from terrestrial transmitters using an [[Television antenna|antenna]] (known as an ''aerial'' in some countries). This delivery method is known as [[digital terrestrial television]] (DTT). With DTT, viewers are limited to channels that have a terrestrial transmitter within range of their antenna.

Other delivery methods include [[digital cable]] and [[digital satellite]]. In some countries where transmissions of TV signals are normally achieved by [[microwaves]], digital [[multichannel multipoint distribution service]] is used. Other standards, such as [[digital multimedia broadcasting]] (DMB) and [[digital video broadcasting - handheld]] (DVB-H), have been devised to allow handheld devices such as [[mobile phones]] to receive TV signals. Another way is [[Internet Protocol television]] (IPTV), which is the delivery of TV over a computer network. Finally, an alternative way is to receive digital TV signals via the open Internet ([[Internet television]]), whether from a central streaming service or a P2P (peer-to-peer) system.

Some signals are protected by [[encryption]] and backed up with the force of law under the [[WIPO Copyright Treaty]] and national legislation implementing it, such as the US [[Digital Millennium Copyright Act]]. Access to encrypted channels can be controlled by a removable card, for example via the [[Common Interface]] or [[CableCard]].
