Digital switchover is the name given to the process in which analogue broadcast television in an area is converted to digital television. A name ( Etymology: from OE nama akin to OHG namo, Latin Nomen, and Greek όνομα ( Digital television (DTV is the sending and receiving of moving images and sound by discrete ( digital) signals in contrast to the analog signals used by It is also sometimes referred to as analogue switchoff. The motivation behind the switch is the improved quality of digital broadcasts over analogue ones and the freeing up of valuable spectrum space for other services (and bidders).

The scale of digital switchover can vary: at one extreme, a small, low-power transmitter can be converted to digital. This is what happened at Ferryside and Llansteffan in the UK, and is normally conducted as a trial, although it can be a permanent change. Ferryside ( Glan y Fferi) is a seaside village in Carmarthenshire, Wales. Llansteffan ( English: church of Stephen) is a village in Carmarthenshire, Wales. At the other extreme, a whole country can be converted from analogue to digital television.

In many countries, a simulcast service is operated where a broadcast is made available to viewers in both analog and digital at the same time. Simulcast is a Portmanteau of " simul taneous broad' cast' " and refers to programs or events broadcast across more than one As digital becomes more popular it is likely that the existing analogue services will be removed. In some cases this has already happened where a broadcaster has offered incentives to viewers to encourage them to switch to digital or simply switched their service regardless of whether they want to switch. In other cases government policies have been introduced to encourage the switch-over process, especially with regard to terrestrial broadcasts.

Government intervention usually involves providing some funding for broadcasters and, in some cases, monetary relief to viewers, to enable a switch-over to happen by a given deadline.

The facility with which digital switchover can be achieved depends not only on the size of the area and number of transmitters to be converted, but also on the number of viewers who rely on the analogue signal as their primary or only means of TV reception. In Berlin, for example, most residents were using cable television, so only a small number of households needed the new equipment necessary for digital reception. On the other hand, around 60% of UK households had access to multi-channel television as of Summer 2005 [1]. This left around 10 million households who would be forced to convert to another means of receiving television by the time digital switchover reaches their area.
