How to use Google Home to stream video to your TV and music to your speakers

Google Home's built-in speaker is merely passable, and the smart-home device doesn't have a display at all. But you can use voice commands to stream music to better speakers and to stream video to your TV. The keys are Google's Google Cast and Android TV technologies. Google Cast is a media-streaming protocol that can be found in Google's own Chromecast (audio and video), Chromecast Audio (audio only), and numerous third-party products. Android TV is a smart TV platform present in various media-streaming boxes and TVs, including models from Nvidia, Xiaomi, Sony, Sharp, and Philips.
