That is the point of the question. If it requires CPU usage, how does it save battery.

I was only guessing about the chrome tab mirroring feature. Are the other features limited to the Pixel?

It only requires CPU usage when it's streaming the contents of your screen. For Youtube/Netflix, all it does is tell the key the url of the stream and everything is done either on the key or the server.

  I don't believe that's correct -- from what I can tell, when it's streaming webpages, it is actually only synchronizing two copies of Chrome -- one on the stick, one on your PC. It is not encoding/transmitting a video, as with AirPlay or Miracast.

    From what do you discern that? Given that everything they showed about the the product was variations of it receiving and decoding a video stream, it would be quite a switch for it to also have a full platform running a web browser in synchronicity. It seems much more likely that it is a direct video send, making it enormously simpler to design.

        Very cool, though incredibly surprising (a browser is an intensive, complex thing, so will people have to constantly be patching their Chromestick?), especially given that once you add the cost of synchronizing all interactions, it seems so much easier to simply video grab the tab. If anyone has this device, what is CPU usage on the source like when tab-casting?

      Just to reply to myself, it seems that they do send encoded video- http://www.reddit.com/r/Android/comments/1j27ro/an_indepth_look_at_how_chromecast_uses_html5/ http://www.reddit.com/r/Android/comments/1j27ro/an_indepth_l...
