{{Further|Countries using DAB/DMB}}
[[Digital Audio Broadcasting]] (DAB), also known as Eureka 147, has been adopted by around 20 countries worldwide. It is based on the [[MPEG-1 Audio Layer II]] [[audio coding format]] and this has been co-ordinated by the [[World DAB Forum|WorldDMB]].

WorldDMB announced in November 2006 that DAB would be adopting the [[HE-AAC]]v2 audio coding format, also known as [[eAAC+]]. Also being adopted are the [[MPEG Surround]] format, and stronger [[error correction coding]] called [[Reed–Solomon error correction|Reed–Solomon]] coding.<ref name="autogenerated1">{{cite web |url=http://www.worlddab.org/upload/uploaddocs/WorldDMBPress%20Release_November.pdf |title=New High Efficiency Audio Option Added for DAB Digital Radio |access-date=2016-02-06 |archive-url=https://web.archive.org/web/20080308204329/http://www.worlddab.org/upload/uploaddocs/WorldDMBPress%20Release_November.pdf |archive-date=2008-03-08 }}</ref> The update has been named [[DAB+]]. Receivers that support the new DAB standard began being released during 2007 with firmware updated available for some older receivers.

DAB and DAB+ cannot be used for mobile TV because they do not include any video codecs. DAB related standards [[Digital Multimedia Broadcasting]] (DMB) and [[DAB-IP]] are suitable for mobile radio and TV both because they have [[MPEG 4 AVC]] and [[WMV9]] respectively as [[video coding format]]s. However a DMB video sub-channel can easily be added to any DAB transmission - as DMB was designed from the outset to be carried on a DAB subchannel. DMB broadcasts in Korea carry conventional MPEG 1 Layer II DAB audio services alongside their DMB video services.
