AppleTV and Embed Code

AppleTV and Embed Code

I'm trying to create a presentation where the embed code shows a countdown timer from another website.  Will Zoho's Show App on the AppleTV do this?
I have a hunch that the AppleTV will force it into it's own sandbox and not allow for extraneous code... Unless it runs on Zoho's server side.  But even then it feels like a bit of a security hole you could drive a truck through.
That said...

It'd be nice to have a countdown timer on my Zoho Slides.
