Is this what we're talking about?


Washington - Dec 16, 2010 - <http://www.nabfastroad.org>NAB Fastroad 
released <http://www.nabfastroad.org/AMDigitalDataSSSRpt.pdf>a report 
on a new AM radio data service concept, with the potential to provide 
AM broadcasters the ability to transmit low-rate data similar to what 
FM broadcasters can provide using the Radio Data System (RDS) 
subcarrier. This work was undertaken by <http://ibiquity.com>iBiquity 
Digital and was co-funded by iBiquity and NAB Fastroad.

Called the AM Digital Data Service (ADDS), this new technology 
supports delivery of low data-rate text for analog AM radio stations, 
which currently have no method for transmitting data such as song 
title and artist. This technology could be easily integrated into 
future radio receivers.

One of the benefits of this service is that it would offer AM 
broadcasters a simpler and less-expensive way to provide a limited 
digital service compared to a full AM IBOC installation, which at 
present is the only option.
