Im britischen XF-Forum hatte ich die Frage nach der Nachruestbarkeit von DAB_
auf einen DAB+ Receiver gestellt.
Innerhalb zweier Tage gab es 87 Sichtungen meines Postings, aber es gab
keiner eine Antwort.
Erklaerbar mag das mit folgender Faktenlage sein:
This may be an explanation of the continental DAB_ and DAB+ situation,

`DAB+
An upgraded version of the system was released in February 2007, which is called DAB+. DAB is not forward compatible with DAB+, which means that DAB-only receivers will not be able to receive DAB+ broadcasts.[7] DAB+ is approximately twice as efficient as DAB due to the adoption of the AAC+ audio codec, and DAB+ can provide high quality audio with as low as 64 kbit/s.[8] Reception quality will also be more robust on DAB+ than on DAB due to the addition of Reed-Solomon error correction coding.
In spectrum management, the bands that are allocated for public DAB services, are abbreviated with T-DAB, where the "T" stands for terrestrial.
More than 20 countries provide DAB transmissions, and several countries, such as Australia, Italy, Malta, Switzerland and Germany,[9] have started transmitting DAB+ stations. See Countries using DAB/DMB. However, DAB radio has still not replaced the old FM system in popularity.
DAB+ United Kingdom
The United Kingdom Government has ruled out any transition from DAB to DAB+ for the foreseeable future, a decision backed by the radio industry and radio industry experts the Department of Media, Culture and Sport consulted with.[48] The chief executive of the DRDB, Tony Moretta, mirrored the calls by the radio industry and experts to not adopt DAB+ in the UK. In an interview with the TechRadar website in 2009, he stated that DAB+ was a "red herring" and may not be introduced in the UK for the foreseeable future due to the growing number of digital radio sets currently being sold and used in the future which cannot decode HE-AAC and therefore access DAB+ stations. Moretta also cited greater expense for broadcasters and overall satisfaction with the current audio quality of DAB stations[49] of which a move to DAB+ would only benefit a small number of audiophiles as other reasons.[50][51] Independent radio analyst Grant Goddard also stated that there was an economic decision not to adopt DAB+ for both the industry and consumers.[48]
The 4Digital Group, led by Channel 4, who were originally awarded the licence to operate the new national DAB multiplex, had planned to launch a podcast service using the DAB+ format.`

Ohne das da oben jetzt uebersetzen zu wollen, ist der logische Inhalt ungefaehr folgender:
Grossbritannien hat sich dazu entschieden in absehbarer Zeit kein DAB+ einzufuehren,
weil die Allgemeinkosten fuer Sender wie fuer den Endverbraucher zu hoch seien,
da z.B. sonst auch fuer den Einzelnen der Zwang zum Neukauf von Rundfunkgeraeten
ins Haus stuende, was bei der hohen, allgemeinen Verbreitung von DAB unzumutbar sei.
