If I am watching a football game that I am streaming on my macbook pro, can I send that live stream to my apple tv?

What I am asking is this -

Let's say I am on a website that has a live stream but is not on regular tv, as long as it is playing on my Macbook, can I send that feed to the Apple TV and watch it on my Big screen tv?


I am new to this so please respond in simple terminology.
