Comment on RDS messaging and messaging on DAB+ and interactivity.
First, it is true that the scrolling text messaging systems on RDS (FM) and DAB+ is limited. The scrolling text is slow and difficult to monetize. The text are limited to displaying weather, traffic, news snippets, music track information and the radio station's talkback line.
It is true that DAB+ has the potential to display graphics such as a radio station's logo but one has not seen DAB+ receivers in the retail stores which display graphical information. That's unless you purchase a DAB+ development kit for engineers,

Displaying moving pictures and having interaction with the radio is quite a novel idea.
But as I said at https://radioinfo.com.au/news/can-the-hd-radio-experience-be-of-use-in-regional-australia-nabshow. I don't approve of interacting with the radio while driving. I've made my point at this page including the legislation to implement the prohibition of interactivity with the radio while driving in the same way that DVD and video from a USB stick with video files cannot operate while the driver is driving.
Have interaction with your radio at home or at work, but not while driving. Furthermore any smart radio should have an "OFF/ON" switch if one wants to or does not want to send back information via a WiFi and/or LAN (RJ45).
Thank you,
