Apple TV Resolution in Full HD Is Apple TV Full HD?

I need to stream video to my TV wirelessly, but necessarly need to be Full HD to use all the TV resolution. 

I think Apple TV is not Full HD, but I don't know if it exist some hardware like it, with same features, but that supports Full HD. What your recommend?

I've researched if Apple is planning to release Apple TV that supports Full HD but I found nothing about.
The apple TV is full HD, this is why you can rent and view full HD films and video content.

However if you are streaming from an iPad, and the video on the iPad is not HD the the content streamed to the TV will not be HD.



Edit

This applies to the previous version of the Apple TV with a built in HD. not the current one. Here is a comparison of the two.
