I just had a quick look and it seems it might do so as there is certainly options to generate artist and track titles or any other text based information from a text file. There is also the following code in the breakawayone-processing config file rds_tp_enable=0
I was wondering the same thing, and tested it the other day. Seems it follows the same syntax as Stereo Tool (not surprising, as I understand BaOne uses the same RDS encoder).
code :Now playing \+TiHeart To Heart\- by \+ArKenny Loggins\-
I've tested it by feeding BaOne's MPX output into the Breakaway Pipeline, which in turn feeds RDS Spy. Now, if only I could find a receiver that supports RT+ for some real-world testing!
Older Apple iPod Nano supports Radio Text Plus (RT+), I know for fact that 2009 and 2010 versions do, unsure about 2012. The new “iPhone look a like” iPod do not have any FM radio.
