Στις ΗΠΑ το FCC προσδιορισε το μέλλον των κενών τηλεοπτικών συχνοτήτων από το 2009 και μετά που υποχρεωτικά όλοι θα εκπέμπουν ψηφιακά.
"The FCC has given its blessing to wireless devices that can't go on sale until 2009, and that operate in vacant television channels; in 2009 all television broadcasters are required to switch to digital transmission.
From the article at Ars Technica: 'Here's how the scheme will work: consumer electronics devices will be allowed to operate in the portion of the TV spectrum being vacated by broadcasters as they switch to digital broadcasts in 2009, with some restrictions. Channel 37 is out — it's used by radio astronomers. Channels 52-69 are also out, since they have been allocated for public safety use. Finally, channels 14-20 might be out (the Commission has asked for more information) because 13 US cities currently use parts of that spectrum for public safety communications.'"

Στην Φιλανδία πρέπει να κλείσουν όλοι το διακόπτη ως τις 31 Αυγούστου 2007:
Analog television broadcasting is coming to an end in Finland. In a recent article, the Finnish News Agency STT reminded viewers that all of that nations television transmissions will switch to digital on August 31st of 2007.
The article noted that as of June of this year, about half the households in Finland with TV sets had acquired a digital adapter, set-top converter box or had purchased new receivers. The European Union recommended all member states complete their transition to all digital operation by 2011 at the latest. (TV Technology)
