I was wondering what exactly are the differences between the Chromecast Ultra and the built in Chromecast Ultra of the Xiaomi Mi Box S. Obviously, the Mi Box doesnt have an ethernet port, but this can be added via USB.
Is the built-in Chromecast driven by a dedicated CPU or does it run together with the AndroidTV system on the Cortex A53? Is there any difference in the behaviour/performance/streaming quality compared to an original Chromecast Ultra?
When you "cast" something you're really just sending an URL and MiBox opens it up with a player or an app. No need for "dedicated" hardware to do that.
MiBox can easily play 4k HDR content so as long as the network connection is sufficient it will be just as good as Chromecast Ultra.
