I want to develop a TV solution that gives me control over some OS-related stuff (like controlling volume level, apps downloads, etc). Something similar to EMM but for TVs. This is to be used for hospitals where certain functionality can be allowed by users.
Is there a way to customize Android TV (even if it requires Google partnership or something)?
If not, are there any other TV operating systems that allow extending/manipulating the OS? Please note that I've explored some "hotel-mode" functionalities from Samsung and LG, and they're not sufficient for my use case.
Thanks in advance.
