The AirTV Player will fuse over-the-air television channels with Sling TV And apps like Netflix. In theory, you'll be able to switch between your city's local weather report and binge-watching The OA without moving between devices. How well this works may be dependent on the type of OTA signal you get in your home, though its possible Sling has a solution that has yet to be announced.
The box is largely white with blue accents, and the remote control shares the same color scheme. There's also a large Google "G" logo on the remote, but the landing page has no details about it. Perhaps the AirTV will have access to the Google Play Store for more apps and services.
There are still a bunch of details we don't know: namely, price and release date, but it wouldn't be surprising to hear more about the AirTV Player at CES 2017 in Las Vegas in January.
