Some SmartTVs (e.g. of LG) offer two platforms in parallel: STA for Portal apps and HbbTV for broadcast-related apps. Both STA and HbbTV have defined their own user agent which can be requested by the app.
Question: Is the user agent the same for both platforms? If yes: How does it look like? And how can the app find out on which platform it is running?
Or are there two different user agent strings depending on which platform is used? (I.e. an STA app would get the one described in the STA specification, and an HbbTV app would get the one defined in the HbbTV specification.)
