DAB is Digital Audio Broadcasting - digital radio in other words. It is becoming well established in Europe (in the UK the BBC are starting to market the technology rather agressively to developers).

In the USA, an alternative DAB standard has been drawn up (quelle surprise). It sidebands onto existing AM and FM stations, making it cheaper to implement - but at the cost of a significantly reduced bitrate. I had a chat with the US DAB people who are still awaiting final approvals from the FCC, and anticipate the first consumer broadcasts in around 12 months. Widespread uptake is expected in within 24 months, which I think may prove to be optimistic.

If we implement a DAB module (and there is certainly some interest in our doing so) we will go for the European standard. There's no point supporting the US system for some considerable time to come.
