I want to be sure that it is known that YouTube TV will not work with a Fire TV or Fire Tv Stick. The best device you can have it on is a Shield TV, which is what I use and it is pretty great. It also works on Apple TV and various other devices. Just not Amazon devices.Not sure I take your meaning. If you purchase YoutubeTV service you would download a YoutubeTV app on your Smart TV, Roku, Amazon Firestick, Google Chromecast, Apple TV, Playstation, or Xbox One and play your content from there. Likewise you can also access your account from your laptop or desktop computer.
The service is hosted online so all you need is internet to access it. That's why those devices I mentioned above that plug into your tv (Roku. Amazon Firestick etc etc) are essential.
Technically you could also tether your laptop to your tv via HDMI if you have the available ports. There are a number of ways to make it happen.
