You can use your existing apps that you already have on your smartphone and have it &quot;cast&quot; to your TV.  &quot;Casting&quot; is simplying saying... take this video link, and play it full screen on my TV.  Or if you were using Spotify, &quot;play my music through the TV, instead of through my phone&quot;.  All the while, you&#x27;re able to keep controlling the experience (pause&#x2F;rewind&#x2F;etc).
