When using Home Sharing from my MacMinni OS 10.6.8 to my Apple TV model A1469 an album from iPhoto projects on my TV great, but will not show the photo captions. Anyway to fix that?

I like to view the photo albums in iPhoto on my Mac minnie, on my TV. On most of the photos in these albums, I have inserted captions on each photo. These display just fine on my computer screen, but when I use home sharing through my Apple TV to my TV the captions are absent. Is there a way to have the captions appear on each photo when viewing them on the TV? My computer uses OS 10.6.8 and my Apple TV model is A1469.
