Creation of DAB+
As DAB is not forward compatible with DAB+, older DAB receivers cannot receive DAB+ broadcasts. However, DAB receivers that were capable of receiving the new DAB+ standard after a firmware upgrade were being sold as early as July 2007. Malta was the first country to launch DAB+ broadcasts in Europe in October 2008 and DAB+ broadcasts have since been trialled or launched in more countries. If DAB+ stations launch in established DAB countries, they can transmit alongside existing DAB stations that use the older MPEG-1 Audio Layer II audio format, and most existing DAB stations are expected to continue broadcasting until the vast majority of receivers support DAB+.
