[i don't think Zidoo X9S have Android TV, for Android TV need lot of certification hardware and software.
I am pretty sure they are running Android Leanback, just go the Google Playstore with it and you will experience the difference yourself. The Realtek chipset + SDK is approved by Google and all platforms using RTD1295 will use Leanback for sure. My statement may be formulated slightly incorrect confusing Android Leanback with Android TV. Android Leanback is the underlying OS and Android TV includes an APP package on top of it.
Don't ask me when something may be called Android TV exactly, but there are 2 different Android OS versions one for smartphones and one for media players inclusive TV's. The later version is normally referred to as Android Leanback. Often the total result is referred to as "SmartTV powered by Android" by TV makers, never see "Android Leanback" mentioned there.
Google TV probably includes also specific APP's and licences not covered by Android Leanback? Google is not really open about all this.
