Audio Description and Apple TV

I rented a movie from iTunes to watch on Apple TV. The description said audio description was available. How do you select audio description? Does it depend on if your TV can accept audio? Mine cannot, as far as I know. Thanks.

#1 it shold be in th apple

Ou can find the option to enable audio description in the settings of your apple tv. I don't think it has anything to do with the tv itself
