The Apple TV is a media streaming device that can be used to watch Live TV Streaming Services. They offer two versions: Apple TV 4K and Apple TV (4th Gen).
The Apple TV 4K is more powerful and can stream 4K at 60 fps. You can control both versions of the Apple TV with the included Siri Remote.
While both devices are more than powerful enough for Streaming Live TV, the $30 premium for the Apple TV 4K is worth the upgrade.
The devices come with access to Apple’s TV App which allows you to browse live and on demand content across 100+ different TV Apps.
