so, now that google announced a Ultra-HD Chromecast; can we expect to see the "google cast" feature on AndroidTV to be UltraHD compatible? on NVidia-Shield, on Sony UHD, or even on MiBox? if Android TV have google cast embedded, it should receive a update to allow for UHD streaming as well
It's just sending a URL. If the device that's pulling down the stream can do 4K, then it should be able to do 4K.
