This will keep radio ahead of the competitive curve in cars: Xperi at #RDE23
28 March 2023 · Conference · News
Xperi has launched a new service that can deliver high quality rich content to listeners’ dashboards and give new insights for programmers into how people are using radio in cars.
Speaking at Rad...

IP-delivered radio is ideal for instaneous delivery of intelligence on users' location via GPS while consuming stations.
I would put caution as to how much information is to be displayed on the dashboard whilst driving. Too much information to display is a distraction from concentrating on the road.
Furthermore in earlier articles on this site about the DTS system interactivity with the motorist, the risk of an accident is increased.
Pro active legislators should limit the use of interactive activity that is non-essential to driving.
For if this interactive dashboard is introduced to cars, more collisions will occur.
Thank you,
Anthony, we need to be pro-active rather than reactive legislation, Belfield, in the land of the Wangal and Darug peoples of the Eora Nation.
DTS Autostage is produced by Xperi who owns the unpopular Hybrid Digital Radio which is only capable of a low data rate which virtually all of it is used for the sound signal(s). As a result, the HDRadio for the sound signal. With the exception of a station logo all other data including images is carried by wireless broadband.
So, the listener must have a phone account for their vehicle, so they can get some pictures, which will probably be mostly advertising? This means that the telco knows which account is being accessed and which phone base station is being used hence gives an approximate location. Will the ratings companies get access to this information in real time? Does the DTS Autostage get the exact vehicle location from the navigation computer in the infotainment system and send it back to the broadcaster along with the number of people in the vehicle and their movements?
Fortunately, in Australia we use DAB+ digital radio, where we divide the channel into 7 commercial and 2 community broadcast 128 kbit/s streams. However, broadcasters can buy part of another broadcaster's allocation. It is up to individual broadcasters to decide how much of the available data is used for multiple sound programs and how much for data. This mix can be changed at will.
By comparison HDRadio has a single 96 kbit/s stream per broadcaster's transmitter. We can use some of the data to transmit slideshow images eg for advertising. All DAB+ vehicle receivers use the infotainment screen.
Digital Radio Mondiale which would be ideal in country areas, which have no digital radio now, can transmit 186 kbit/s in the 47 - 68, and 87.5 - 108 MHz bands.
How useful will the statistics be for broadcasters, when the listener has to buy a phone account for their car, how much will the data cost, the privacy/hacking possibilities and the fact that only 19 % of the Australian landmass is covered by mobile signals. Potentially this means that every listener will need access to a mobile phone base station which has to have a transmit/receiver for each simultaneous listener in addition to normal traffic now. Depending on how often the information is transmitted this will require a massive and expensive increase in base station capacity and spectrum which will need to be paid for. I suppose they expect this from high speed 5G which requires micro base stations 900 metres apart.
